                                  MAY 12, 2005

To Our Stockholders:
 
     Core Molding Technologies, Inc. ("Core Molding Technologies") is furnishing
this Proxy Statement in connection with the solicitation by its Board of
Directors of proxies to be used and voted at its annual meeting of stockholders,
and at any adjournment of the annual meeting. Core Molding Technologies will
hold its annual meeting on May 12, 2005, at its corporate headquarters, 800
Manor Park Drive, Columbus, Ohio 43228 at 9:00 a.m. Eastern Standard Time. Core
Molding Technologies is holding the annual meeting for the purposes set forth in
the accompanying Notice of Annual Meeting of Stockholders.
 
     Core Molding Technologies is first sending this Proxy Statement, the
accompanying proxy card and the Notice of Annual Meeting of Stockholders on or
about April 15, 2005.
 
                              GENERAL INFORMATION
 
SOLICITATION
 
     The Board of Directors of Core Molding Technologies is soliciting the
enclosed proxy. In addition to the use of the mail, directors and officers of
Core Molding Technologies may solicit proxies, personally or by telephone or
telegraph. Core Molding Technologies will not pay its directors and officers any
additional compensation for the solicitation.
 
     In addition, the stock transfer agent of Core Molding Technologies,
American Stock Transfer & Trust Co., New York, New York will conduct proxy
solicitations on behalf of Core Molding Technologies. Core Molding Technologies
will reimburse American Stock Transfer & Trust Co. for reasonable expenses
incurred by it in the solicitation. Core Molding Technologies also will make
arrangements with brokerage firms and other custodians, nominees and fiduciaries
for the forwarding of proxy solicitation material to beneficial owners of the
common stock of Core Molding Technologies. Core Molding Technologies will
reimburse those brokerage firms, custodians, nominees and fiduciaries for their
reasonable expenses.
 
     Core Molding Technologies will pay all expenses of the proxy solicitation.
Except as otherwise provided, Core Molding Technologies will not use specially
engaged employees or other paid solicitors to conduct any proxy solicitation.
 
VOTING RIGHTS AND VOTES REQUIRED
 
     Holders of shares of the common stock of Core Molding Technologies at the
close of business on March 30, 2005, the record date for the annual meeting, are
entitled to notice of, and to vote at, the annual meeting. On the record date,
Core Molding Technologies had 9,780,680 shares of common stock outstanding.
 
     Each outstanding share of common stock on the record date is entitled to
one vote on all matters presented at the annual meeting. The presence, in person
or by proxy, of stockholders entitled to cast a majority of all the votes
entitled to be cast will constitute a quorum for the transaction of business at
the annual meeting. No business, other than adjournment, can be conducted at the
annual meeting unless a quorum is present in person or by proxy.
 
                                        1

 
     Abstentions will count as shares present in determining the presence of a
quorum for a particular matter. Abstentions, however, will not count as votes
cast in determining the approval of any matter by the stockholders. If a broker
or other record holder or nominee indicates on a proxy that it does not have
authority to vote certain shares on a particular matter or if a broker or other
record holder or nominee does not return proxies for any shares, those shares
will not count as either present for purposes of determining a quorum or as
votes cast in determining the approval of any matter by the stockholders.
 
     In the election of directors, each of the seven directors will be elected
by a plurality of votes cast by stockholders of record on the record date and
present at the annual meeting, in person or by proxy. Cumulative voting in the
election of directors will not be permitted. Core Molding Technologies is
seeking stockholder ratification of the appointment of independent auditors of
Core Molding Technologies, but ratification is not required by law.
 
VOTING OF PROXIES
 
     Shares of common stock represented by all properly executed proxies
received prior to the annual meeting will be voted in accordance with the
choices specified in the proxy. Unless contrary instructions are indicated on
the proxy, the shares will be voted:
 
     - FOR the election as directors of the nominees named in this Proxy
       Statement;
 
     - FOR the ratification of the appointment of Deloitte & Touche LLP
       ("Deloitte & Touche"), as the independent registered public accounting
       firm for Core Molding Technologies for the year ending December 31, 2005.
 
     Management of Core Molding Technologies and the Board of Directors of Core
Molding Technologies know of no matters to be brought before the annual meeting
other than as set forth in this Proxy Statement. If, however, any other matter
is properly presented to the stockholders for action, it is the intention of the
holders of the proxies to vote at their discretion on all matters on which the
shares of common stock represented by proxies are entitled to vote.
 
REVOCABILITY OF PROXY
 
     A stockholder who signs and returns a proxy in the accompanying form may
revoke it at any time before the authority granted by the proxy is exercised. A
stockholder may revoke a proxy by delivering a written statement to the
Secretary of Core Molding Technologies that the proxy is revoked.
 
ANNUAL REPORT
 
     The Annual Report on Form 10-K for the fiscal year ended December 31, 2004,
of Core Molding Technologies, which includes financial statements and
information concerning the operations of Core Molding Technologies, accompanies
this Proxy Statement. The Annual Report is not to be regarded as proxy
solicitation materials.
 
STOCKHOLDER PROPOSALS
 
     Any stockholder who desires to present a proposal for consideration at the
2006 annual meeting of stockholders must submit the proposal in writing to Core
Molding Technologies. If the proposal is received by Core Molding Technologies
prior to the close of business on December 15, 2005, and otherwise meets the

include the proposal in the proxy statement and form of proxy relating to the
2006 annual meeting of stockholders. Core Molding Technologies may confer on the

vote on any proposal, if Core Molding Technologies does not receive notice of

                                        8

 
  COMPENSATION COMMITTEE
 
     Core Molding Technologies did not have a Compensation Committee during the
fiscal year ended December 31, 2004. The entire Board of Directors performed the
functions of a Compensation Committee during that period, including recommending
the form and amount of compensation to be paid to the executive officers and
directors of Core Molding Technologies.
 
  AUDIT COMMITTEE
 
     Core Molding Technologies has an Audit Committee, which currently consists
of Messrs. Crowley, Hellmold, and Wright, each of whom is "independent" as that
term is defined under AMEX listing standards. The Board has determined that Mr.
Crowley qualifies as an "audit committee financial expert" as defined by
Securities and Exchange Commission rules. The principal function of the Audit
Committee is to review and approve the scope of the annual audit undertaken by
the independent registered public accounting firm of Core Molding Technologies
and to meet with them to review and inquire as to audit functions and other
financial matters and to review the year-end audited financial statements. For a
more detailed description of the role of the Audit Committee, see "Report of the
Audit Committee" below and the Audit Committee Charter, which is attached to
this Proxy Statement as Exhibit A. The Audit Committee met seven times during
the fiscal year ended December 31, 2004. In addition, the Committee chair, as
representative of the Committee, discussed the interim financial information
contained in quarterly earnings announcements with both management and the
independent auditors prior to the public release of quarterly information.
 
  NOMINATING COMMITTEE AND STOCKHOLDER NOMINATIONS
 
     Core Molding Technologies has a Nominating Committee consisting of all
members of the Board of Directors, with a majority of directors who are
independent under AMEX listing standards required to effect a decision. The
principal function of the Nominating Committee is to recommend candidates for
membership on the Board of Directors. For a more detailed description of the
role of the Nominating Committee, see the Nominating Committee Charter, which is
attached to this Proxy Statement as Exhibit B.
 
     In identifying and evaluating nominees for director, the Nominating
Committee seeks to ensure that the Board possesses, in the aggregate, the
strategic, managerial and financial skills and experience necessary to fulfill
its duties and to achieve its objectives, and seeks to ensure that the Board is
comprised of directors who possess knowledge in areas that are of importance to
Core Molding Technologies. In addition, the Nominating Committee believes it is
important that at least one director have the requisite experience and expertise
to be designated as an "audit committee financial expert." The Nominating
Committee looks at each nominee on a case-by-case basis regardless of who
recommended the nominee.
 
     The Nominating Committee will consider persons recommended by stockholders
to become nominees for election as directors. Recommendations for consideration
by the Nominating Committee should be sent to the Secretary of Core Molding
Technologies in writing together with appropriate biographical information
concerning each proposed nominee.
 
     The bylaws of Core Molding Technologies set forth procedural requirements
pursuant to which stockholders may make nominations to the Board of Directors.
The Board of Directors or the Nominating Committee may not accept
recommendations for nominations to the Board of Directors in contravention of
these procedural requirements.
 
     In order for a stockholder to nominate a person for election to the Board
of Directors, the stockholder must give written notice of the stockholder's
intent to make the nomination either by personal delivery or by United States
mail, postage prepaid, to the Secretary of Core Molding Technologies not less
than fifty nor more than seventy-five days prior to the meeting at which
directors will be elected. In the event that less than sixty days prior notice
or prior public disclosure of the date of the meeting is given or made to
stockholders, Core Molding Technologies must receive notice not later than the
close of business on the tenth day following the day on which notice of the date
of the meeting was mailed or public disclosure was made, whichever occurred
first.
 
                                        9

 
     The notice must set forth:
 
     - the name and address of record of the stockholder who intends to make the
       nomination;
 
     - a representation that the stockholder is a holder of record of shares of
       the capital stock of Core Molding Technologies entitled to vote at the
       meeting and intends to appear in person or by proxy at the meeting to
       nominate the person or persons specified in the notice;
 
     - the name, age, business and residence addresses and principal occupation
       or employment of each proposed nominee;
 
     - a description of all arrangements or understandings between the
       stockholder and each proposed nominee and any other person or persons,
       naming such person or persons, pursuant to which the nomination or
       nominations are to be made by the stockholder;
 
     - other information regarding each proposed nominee as would be required to
       be included in a proxy statement filed pursuant to the proxy rules of the
       Securities and Exchange Commission; and
 
     - the written consent of each proposed nominee to serve as a director of
       Core Molding Technologies if elected.
 
     Core Molding Technologies may require any proposed nominee to furnish other
information as it may reasonably require to determine the eligibility of the
proposed nominee to serve as a director. The presiding officer of the meeting of
stockholders may, if the facts warrant, determine that a stockholder did not
make a nomination in accordance with the foregoing procedure. If the presiding
officer makes such a determination, the officer shall declare such determination
at the meeting and the defective nomination will be disregarded.
 
     BOARD POLICIES REGARDING COMMUNICATION WITH THE BOARD OF DIRECTORS AND
                         ATTENDANCE AT ANNUAL MEETINGS
 
     Stockholders may communicate with the full Board, non-management directors
as a group, or individual directors, including the Chairman of the Board, by
submitting such communications in writing to the Core Molding Technologies
Secretary, c/o the Board of Directors (or, at the stockholder's option, c/o a
specific director or directors), 800 Manor Park Drive, Columbus, Ohio 43228.
Such communications will be delivered directly to the Board.
 
     Core Molding Technologies does not have a policy regarding Board member
attendance at the annual meeting of stockholders. All Core Molding Technologies
directors attended the 2004 annual meeting of stockholders.

    Technologies on December 31, 2004 ($2.77) less the exercise price of in-the
    money options/SARs at the end of the fiscal year ended December 31, 2004.
 
(2) Securities acquired on exercise for Messrs. Simonton, Klestinec and Dick
    include shares purchased pursuant to the Core Molding Technologies Employee
    Stock Purchase Plan. Value realized represents the difference between the
    market price of the shares on the applicable purchase dates and the purchase
    prices paid by such officers.
 
PHANTOM STOCK AGREEMENT
 
     On January 15, 2000, Core Molding Technologies granted Mr. Simonton, in
connection with his initial employment, 150,000 phantom stock units pursuant to
a Phantom Stock Agreement dated as of January 15, 2000.
 
                                        12

 
Pursuant to such agreement, Mr. Simonton is entitled to receive within 30 days
after exercise of each such unit a cash payment in an amount equal to the excess
of the fair market value of a share of Core Molding Technologies' common stock
on the date of exercise over $2.75. Mr. Simonton may exercise his vested units
at any time prior to their termination. All of the units vest on December 31,
2004, and no units granted under the agreement will vest prior to such date. All
of the units will expire on the earlier of (i) December 31, 2005, (ii) 30 days
after termination of Mr. Simonton's employment (other than for cause) or if Mr.
Simonton shall die during such 30-day period, one year after Mr. Simonton's
death or (iii) the termination of Mr. Simonton's employment by Core Molding
Technologies for cause. Within 30 days after the termination of Mr. Simonton's
employment due to death or disability, Core Molding Technologies is required
under the agreement to pay Mr. Simonton the full amount that would have been
payable to Mr. Simonton had he exercised all of the unexercised vested units
held by him as of the date of his termination of employment. The units were not
granted to Mr. Simonton under the Core Molding Technologies, Inc. Long-Term
Equity Incentive Plan. The units do not represent issued shares of Core Molding
Technologies' common stock and do not confer any stockholder rights on Mr.
Simonton.
 
           REPORT OF THE BOARD OF DIRECTORS ON EXECUTIVE COMPENSATION
 
     The purpose of the compensation program of Core Molding Technologies is to
attract and retain qualified executive officers by providing a total
compensation package, which is competitive with comparable corporations, and to
also provide incentives to create short-term and long-term improvements in the
performance of Core Molding Technologies.
 
     The compensation philosophy of Core Molding Technologies is based on the
belief that:
 
     - Core Molding Technologies must attract and retain qualified individuals
       and motivate and reward those individuals for performance;
 
     - a substantial portion of an executive's compensation should depend upon
       the performance of Core Molding Technologies; and
 
     - incentives should exist which align the interests of the executives with
       those of the stockholders of Core Molding Technologies and which create
       long-term stockholder value.
 
     Following this philosophy, Core Molding Technologies has developed a
compensation program for its executives which includes the following components:
 
BASE SALARY
 
     Core Molding Technologies has established base salaries for its executive
officers based upon the experience and capabilities of the executives, as
determined in the subjective judgment of the Board of Directors, and the
salaries of comparable companies.
 
BONUS/PROFIT SHARING
 
     The Board of Directors has established a bonus/profit-sharing program for
all nonrepresented and salaried employees, including its executive officers, of
Core Molding Technologies. This program is designed to align the interests of
such individuals with those of the stockholders of Core Molding Technologies by
directly tying profit sharing payments to the performance of Core Molding
Technologies. This program creates a profit sharing pool for all nonrepresented
and salaried employees, including its executive officers, based upon percentages
of the earnings before taxes of Core Molding Technologies that exceed
pre-established thresholds. The thresholds are established by the Board of
Directors and are intended to begin creating a profit sharing pool only after
earnings before taxes exceeds a reasonable level. A total of $1,284,000 was paid
out to all nonrepresented and salaried employees, including its executive
officers, under this bonus/profit-sharing plan in 2005 for the performance
achieved in 2004.
 
                                        13

 
STOCK OPTIONS AND EMPLOYEE STOCK PURCHASE PLAN
 
     The Board of Directors grants stock options under the Core Molding
Technologies, Inc. Long-Term Equity Incentive Plan to executives and salaried
employees, which are intended to align the long-term interests of these
individuals with the interests of the stockholders of Core Molding Technologies.
The Board of Directors determines the options awarded to the executive officers
based upon the subjective judgment and experience of the directors in
compensating executive officers. Options for the executive officers are
generally granted at or above fair market value and are subject to a ten-year
vesting schedule.
 
     In addition to the Long-Term Equity Incentive Plan, the stockholders of
Core Molding Technologies approved in 2002 an Employee Stock Purchase Plan (the
"Stock Purchase Plan"). Once effective, all eligible employees, including
executive officers, may purchase shares pursuant to the Stock Purchase Plan
through payroll deductions at a price equal to 85% of the fair market value of
Core Molding Technologies' common stock.
 
BASIS FOR CHIEF EXECUTIVE OFFICER'S COMPENSATION
 
     The Board of Directors established compensation for Mr. Simonton for 2004
in accordance with the information discussed above.
 
                                          Submitted by the Board of Directors,

          COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     Core Molding Technologies did not have a Compensation Committee during the

     Finally, Mr. Prine was granted a stock option to purchase 70,000 shares of
Core Molding Technologies' stock on February 4, 1998, as consideration for his
services. The option vests in increments of 20% over a five-year period and
expires on February 4, 2008. The option was granted at an exercise price of
$3.97 per share, representing the fair market value on the date of grant. In
July 2003, Mr. Prine elected to have these options canceled as a part of Core
Molding Technologies' option repricing tender offer. Mr. Prine was reissued
66,500 options on February 9, 2004 at an exercise price of $3.21. The options
are fully vested and expire on February 9, 2014.
 
RELATIONSHIP WITH MR. SIMONTON
 
     On January 15, 2000, Mr. Simonton was elected President and Chief Executive
Officer of Core Molding Technologies. Mr. Simonton has served as a director at

2004. International is also a 44% stockholder in Core Molding Technologies. As a
director, Mr. Simonton participates in deliberations of Core Molding
Technologies' Board of Directors concerning executive officer compensation.
However, Mr. Simonton has and intends to continue to abstain from participating
in any actions of the Board of Directors affecting his compensation.

                         REPORT OF THE AUDIT COMMITTEE
 
     The Audit Committee of the Board of Directors ("Committee") is composed of
three directors, none of whom is an employee of Core Molding Technologies. The
Committee is governed by a charter as approved by the Board of Directors
("Board") on March 27, 2000, and reviewed and thereafter ratified by the Board
at the Board's May 13, 2004 meeting. A copy of the charter is attached as
Exhibit A. In accordance with its written charter, the Committee assists the
Board in fulfilling its responsibility for oversight of the quality and
integrity of the accounting, auditing and financial reporting practices of Core
Molding Technologies.
 
     During the year ended December 31, 2004, the Committee met seven times and

     In discharging its oversight responsibility as to the audit process, the
Committee obtained from Deloitte & Touche a formal written statement describing

Standard No. 1 "Independence Discussions with Audit Committees," discussed with
Deloitte & Touche, any relationships that may impact their objectivity and

communications required by auditing standards generally accepted in the United
States of America, including those described in Statement on Auditing Standards
No. 61, as amended "Communication with Audit Committees" and, with and without

examination of the financial statements.
 
     The Committee reviewed the audited consolidated financial statements of
Core Molding Technologies as of and for the year ended December 31, 2004, with

preparation of the Company's financial statements and Deloitte & Touche has the
responsibility for the examination of those statements.

Deloitte & Touche, the Committee recommended to the Board that audited
consolidated financial statements be included in its Annual Report on Form 10-K
for the fiscal year ended December 31, 2004, for filing with the Securities and
Exchange Commission.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
RELATIONSHIP WITH INTERNATIONAL TRUCK AND ENGINE CORPORATION (INTERNATIONAL)
 
     On October 8, 1996, RYMAC Mortgage Investment Corporation, a Maryland
corporation, formed Core Molding Technologies as a wholly owned subsidiary under
the laws of the State of Delaware. RYMAC incorporated Core Molding Technologies
in order to acquire substantially all of the assets of the Columbus Plastics
operating unit of International Truck and Engine Corp.
 
     Pursuant to the terms of the asset purchase agreement with International,
Core Molding Technologies acquired substantially all of the assets and
liabilities of Columbus Plastics on December 31, 1996. As consideration,
International received a secured note in the principal amount of $25,504,000.
International also received 4,264,000 shares of newly issued common stock of
Core Molding Technologies, representing approximately 45% of the total number of
shares of common stock issued and outstanding at the time of the acquisition.
The principal amount of the secured note and the number of shares of common
stock received by International were subject to adjustment pursuant to the terms
of the asset purchase agreement.
 
     International's acquisition of common stock of Core Molding Technologies
made it the largest stockholder of Core Molding Technologies. The certificate of
incorporation of Core Molding Technologies protects this position by limiting
the possibility of a change in ownership or control. For instance, the
certificate of incorporation requires a super-majority vote to remove directors
or to approve certain extraordinary corporate transactions, including mergers
and acquisitions. The certificate of incorporation also restricts transfers of
securities, which could result in a change of ownership of a specified
percentage in Core Molding Technologies. This restrictive transfer provision is
discussed below under the heading "Limitation on Ownership."
 
     International's status as the largest stockholder of Core Molding
Technologies has allowed International in the past, and will allow International
at the annual meeting, to influence the composition of the Board of Directors.
Core Molding Technologies anticipates that the stockholders will elect Mr. Hough
and Mr. Cellitti, currently officers of International, as directors of Core
Molding Technologies at the annual meeting.
 
     In addition to being the largest stockholder of Core Molding Technologies,
International is also a significant customer of Core Molding Technologies with
sales to International representing approximately 54% of total revenues of Core
Molding Technologies during the fiscal year ended December 31, 2004. Core
Molding Technologies and International entered into a registration rights
agreement at the time of the merger and acquisition under which Core Molding
Technologies granted to International demand and piggy-back rights with respect
to the registration for sale under the Securities Act of 1933 of the shares of
common stock received pursuant to the asset purchase agreement.
 
OTHER MATERIAL RELATIONSHIPS
 
     Core Molding Technologies has entered into material arrangements with
members of its Board of Directors which arrangements are discussed above under
the heading "Compensation Committee Interlocks and Insider Participation."
 
                            LIMITATION ON OWNERSHIP
 
     The certificate of incorporation of Core Molding Technologies contains a
prohibited transfer provision, which was designed at the time of the merger and
acquisition to help assure the continued availability of Core Molding
Technologies' substantial net operating losses by seeking to prevent an
ownership change in Core Molding Technologies.
 
     The prohibited transfer provision prohibits a transfer of stock of Core
Molding Technologies if the transfer will cause the transferee to hold a
prohibited ownership percentage or if the transferee's ownership percentage
already exceeds the prohibited ownership percentage. The prohibited transfer
provision defines "stock" as including all classes of stock, options to purchase
stock or any other interest in Core Molding Technologies that could be treated
as stock. A prohibited ownership percentage generally means direct and indirect
ownership of
 
                                        19

 
4.5% or more of the stock or any other percentage that would cause a transferee
to be considered a five percent stockholder under the federal income tax rules
referenced in the certificate of incorporation.
 
     The prohibited transfer provision did not apply to the issuance of stock to
International pursuant to the asset purchase agreement and will not restrict
certain transfers that are made in compliance with exceptions set forth in the
prohibited transfer provision.
 
     In addition, Core Molding Technologies' Certificate of Incorporation and
By-laws contain certain provisions designed to discourage specific types of
transactions involving an actual or threatened change of control of Core Molding
Technologies. These provisions, which are designed to make it more difficult to
change majority control of the Board of Directors without its consent, include
the following:
 
          Removal of Directors -- This provision provides that a director of
     Core Molding Technologies may be removed with or without cause only upon
     the vote of the holders of at least 80% of the voting power of the
     outstanding shares of capital stock entitled to vote generally in the
     election of directors.
 
          Supermajority Approval -- This provision requires that a merger and
     certain other transactions (as outlined in the Certificate of
     Incorporation) be approved by the affirmative vote of the holders of at
     least 66 2/3% of the then outstanding shares of Core Molding Technologies'
     common stock. Such affirmative vote is required not withstanding the fact
     that no vote may be required, or that a lesser percentage may be specified
     by law.
 
          Amendments -- This provision requires that any amendment to the
     provisions relating to the removal of directors be approved by the holders
     of at least 80% of the then outstanding shares of voting stock, and any
     amendment to provisions requiring the approval of the holders of at least
     66 2/3% of the then outstanding shares of voting stock be approved by the
     holders of at least 66 2/3% of the then outstanding shares of voting stock.
 
                                 PROPOSAL NO. 1
                             ELECTION OF DIRECTORS
 
COMPOSITION OF THE BOARD OF DIRECTORS
 
     The Board of Directors currently consists of seven members. At the annual
meeting, the stockholders will elect seven directors to hold office until the
election and qualification of their successors at the next annual meeting of
stockholders or until their earlier resignation, death, disqualification or
removal from office.
 
     The intention of the proxies is to vote the shares of common stock they
represent for the election of Thomas R. Cellitti, James F. Crowley, Ralph O.
Hellmold, Thomas M. Hough, Malcolm M. Prine, James L. Simonton and John P.
Wright unless the proxy is marked to indicate that such authorization is
expressly withheld. Each of the nominees is currently a member of the Board of
Directors. All of the nominees have stated their willingness to serve and Core
Molding Technologies is not aware of any reason that would cause any of the
nominees to be unavailable to serve as a director should they be elected at the
annual meeting. If any of the nominees should become unavailable for election,
the proxies may exercise discretionary authority to vote for a substitute
nominee proposed by the Board of Directors. Information with respect to the
background and experience of each of the seven nominees is set forth above under
the heading "Directors and Executive Officers of Core Molding Technologies."
 
     Under Delaware law and the bylaws of Core Molding Technologies, the
stockholders will elect as directors the seven nominees receiving the greatest
number of votes. Core Molding Technologies will count shares of common stock as
to which voting authority is withheld for quorum purposes but will not count
those shares toward the election of directors or toward the election of
individual nominees specified in the form of proxy.
 
     YOUR BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE ELECTION OF MESSRS.
CELLITTI, CROWLEY, HELLMOLD, HOUGH, PRINE, SIMONTON AND WRIGHT.

                                   PROPOSAL 2
                   RATIFICATION OF APPOINTMENT OF INDEPENDENT
                       REGISTERED PUBLIC ACCOUNTING FIRM
 
     The Audit Committee of the Board of Directors has appointed the firm of
Deloitte & Touche to audit the financial statements of Core Molding Technologies
for the fiscal year ending December 31, 2005. Core Molding Technologies expects
a representative of Deloitte & Touche to attend the annual meeting. Core Molding
Technologies will provide the representative with an opportunity to make a
statement if he or she desires to do so. Core Molding Technologies expects that
the representative will be available to respond to appropriate questions.
 
     Core Molding Technologies is presenting the appointment of Deloitte &
Touche as independent registered public accounting firm to the stockholders for
ratification at the annual meeting. While ratification by stockholders of this
appointment is not required by law or the certificate of incorporation or bylaws
of Core Molding Technologies, management believes that such ratification is
desirable. In the event this appointment is not ratified by a majority vote of
stockholders, the Audit Committee will consider that fact when it appoints an
independent registered public accounting firm for the next fiscal year. The
Board has adopted policies requiring the Audit Committee to pre-approve all
audit and non-audit services provided by Core Molding Technologies' independent
registered public accounting firm. All auditing services and non-audit services
provided by Deloitte & Touche for the year ended December 31, 2004 have been
approved by the Audit Committee.
 
     YOUR BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE PROPOSAL TO RATIFY THE
APPOINTMENT OF DELOITTE & TOUCHE LLP.
 
                                 OTHER MATTERS
 
     The management of Core Molding Technologies and the Board of Directors of
Core Molding Technologies know of no matters to be brought before the annual
meeting other than as set forth above. If, however, any other matters are
properly presented to the stockholders for action, it is the intention of the
persons named in the proxy to vote at their discretion on all matters on which
the shares of common stock represented by such proxies are entitled to vote.
 
                                          BY ORDER OF THE BOARD OF DIRECTORS

                        CORE MOLDING TECHNOLOGIES, INC.
 
                            AUDIT COMMITTEE CHARTER
 
     The Audit Committee is appointed by the Board of Directors of Core Molding
Technologies, Inc. (the "Corporation") to assist the Board in fulfilling its
responsibility for oversight of the quality and integrity of the accounting,
auditing and reporting practices of the corporation and other such duties as
directed by the Board.
 
     The membership of the committee shall consist of at least three independent
directors who are generally knowledgeable in financial and auditing matters,
including at least one member with accounting or related financial management
expertise. Once a year, there will be a written affirmation of compliance to The
American Stock Exchange on the financial literacy of all Audit Committee members
and the financial management expertise of one member. Each member shall be free
of any relationship that, in the opinion of the board, would interfere with his
or her individual exercise of independent judgment, and shall meet the
composition requirements as set forth in the Audit Committee standards of The
American Stock Exchange and as both may be amended over time. One of the Audit
Committee members shall be appointed by the Board to chair the Audit Committee.
He or she shall be responsible for leadership of the committee, including
reviewing the agenda, presiding over the meetings, making committee assignments
and reporting to the board of directors. The chairperson will also maintain
regular liaison with the management of the corporation, and the lead independent
audit partner.
 
     The committee is empowered to investigate any matter brought to its
attention, with full power to retain outside counsel or other experts for this
purpose. In carrying out these responsibilities, the Committee shall have full
access to the independent public accountants, the general counsel, any of the
Corporation's non-employee attorneys and advisors, and executive and financial
management in scheduled joint sessions or private meetings. Similarly, the
Corporation's independent public accountants, general counsel, and executive and
financial management will have full access to the Committee and to the Board of
Directors and each is responsible for bringing before this Committee or its
Chair in a timely manner any matter he/she feels appropriate to the discharge of
the Committee's responsibility.
 
     The Audit Committee will reassess the Charter annually and present it to
the Board for their formal review and approval. There will be an annual written
affirmation of compliance addressed to The American Stock Exchange that the
Board has approved the Charter. The Audit Committee will publish an annual
statement in the proxy statement, which sets forth the composition of the Audit
Committee along with a discussion of the actions taken during the year. In
addition, the Audit Committee Charter will be published in the annual report or
proxy statement every year.
 
     The function of the Audit Committee shall be to advise Management and to
exercise the following powers and duties with respect to the following matters
involving the Corporation and, unless otherwise specified, any of its direct or
indirect subsidiaries ("Corporation"):
 
     1. Review Corporation's annual financial statements, annual reports,
        registration statements, and material amendments to any of them, as
        filed with the U.S. Securities and Exchange Commission; and recommend to
        the Board the inclusion of the company's audited financial statements in
        the company's annual report on Form 10-K. The review shall include
        consideration of the quality of the Corporation's accounting principles
        as applied in its financial reporting.
 
     2. Review with management and the independent auditor the quarterly
        financial information prior to the Corporation's filing of the Form
        10-Q. This review may be performed by the committee or its chairperson.
 
     3. Review the Corporation's programs for compliance with the financial
        disclosure requirements of applicable law.
 
     4. Review the auditing of the Corporation's accounts with the independent
        public accountant, including the plan, and the results of their auditing
        engagements.
 
                                       A-1

 
     5. Select and retain the independent public accountant to audit the
        financial statements of the Corporation. In so doing, the committee will
        request from the public accountant a written affirmation that the public
        accountant is in fact independent, discuss with the public accountant
        any relationships that may impact the auditor's independence, and
        recommend to the Board any actions necessary to oversee the public
        accountant's independence. The independent public accountant is
        ultimately accountable to the Board of Directors and the Audit
        Committee.
 
     6. Review the Corporation's processes to maintain an adequate system of
        internal controls.
 
     7. Discuss with management the status of pending litigation, taxation
        matters and other areas of oversight to the legal and compliance area as
        may be appropriate.
 
     8. Present to the Board any proposal received from any shareholder
        concerning any of the foregoing matters, which the shareholder proposes
        to present for action by the Corporation's shareholders.
 
     9. Perform such other duties and responsibilities as may be assigned to the
        Audit Committee by the Board.

                                                                       EXHIBIT B
 
                        CORE MOLDING TECHNOLOGIES, INC.
 
         Charter of the Nominating Committee of the Board of Directors
 
I.  Structure of Committee
 
     This Charter governs the structure and operation of the Nominating
Committee (the "Committee"). The Committee's role, as more specifically
described below, is to identify and evaluate persons qualified for presentation
as Director nominees, to present to the Board of Directors (the "Board")
qualified slates of nominees for election to the Board by the Company's
shareholders, to recommend candidates to fill vacancies occurring between annual
shareholder meetings and to carry out all obligations imposed upon a nominating
committee pursuant to the rules and regulations of the Securities and Exchange
Commission ("SEC") and of the American Stock Exchange ("AMEX") as the same may
be applicable from time to time.
 
     The Committee shall be comprised of all members of the Board of Directors
with a majority of independent Directors (under AMEX rules) required to effect a
decision. Each member shall serve for a term expiring at the next annual meeting
of Directors and may be removed by the Board at any time.
 
II.  Meetings
 
     The Committee shall meet as often as deemed necessary. Electronic
participation in meetings is acceptable if effected in compliance with the
Company's Bylaws. The Committee shall have authority, in its areas of
responsibility, to retain at Company expense independent advisors and to approve
and require payment of fees charged by such advisors. In the performance of its
duties, the Committee and its Members shall have unrestricted access to
management.
 
     The Committee shall cause appropriate minutes to be prepared and preserved
with respect to its proceedings and shall report its actions to the next
following meeting of the Board.
 
III.  Duties and Responsibilities
 
     In discharging its duties, the Committee shall perform the following
activities as well as such additional activities as it deems appropriate in
light of then applicable rules and regulations of the SEC and AMEX:
 
          A. To identify and review, in consultation with the Company's Chief
     Executive Officer, candidates for the Board of Directors and to recommend
     to the Board candidates for election to the Board. Such recommendation
     shall disclose the source from which the recommendation of such candidate
     came.
 
          B. To evaluate and measure those skills and accomplishments which
     should be possessed by a prospective member of the Board given the then
     membership of the Board, including such factors as the ethical values,
     personal integrity and business reputation of the candidate, his or her
     financial acumen, reputation for effective exercise of sound business
     judgment, strategic planning capability, indicated interest in providing
     attention to the duties of a member of the Board, contribution of a diverse
     frame of reference, personal skills in marketing, manufacturing processes,
     technology or in other areas where such person's talents may contribute to
     the effective performance by the Board of its responsibilities.
 
          C. To review the Committee Charter from time to time for adequacy in
     light of current conditions and to recommend any appropriate changes to the
     Board, including, without limitation, those changes which may be required
     by the SEC with respect to the process of receipt and review of
     recommendations from shareholders regarding possible Board candidates.
 
          D. To consider and review the qualifications of those Director
     candidates recommended by shareholders in a fair and unbiased manner and by
     application of the same tests and standards which are considered in
     connection with candidates independently identified by the Committee or
     otherwise brought to its attention including, without limitation, those
     factors described in III. B., above. In order to allow the Committee
     sufficient time to evaluate candidates relative to the standards set forth
     in this Charter, recommendations from shareholders regarding candidates
     must be delivered to the Company's Secretary at least 90 days prior
 
                                       B-1

 
     to the Company's annual meeting, provided that recommendations received
     after such deadline may still be considered if the Committee determines
     that their review process will not be compromised by such delinquent
     notice. Such recommendations must be in writing and must include a
     biographical description of the prior relevant activities of the proposed
     candidate and the views of the recommending shareholder regarding his or
     her qualifications. Such recommendations must be accompanied a written
     statement from the proposed candidate agreeing to be identified in the
     proxy statement as a nominee and, if elected, to serve as a Director.
 
          E. To report to the Board regarding the number and identity of
     Directors who were present and who were absent at the most recent annual
     shareholders meeting and to encourage attendance by Board Members at all
     shareholder annual meetings.
 
          F. To develop and, following approval thereof by the Board, to
     implement a process for the receipt of communications from shareholders to
     Directors.
 
                                       B-2
