         CORE MOLDING TECHNOLOGIES REPORTS SECOND QUARTER 2004 RESULTS

COLUMBUS, Ohio - August 17, 2004 - Core Molding Technologies, Inc. (AMEX: CMT)
today announced results for the second quarter and six months ended June 30,
2004.

         The Company recorded net income for the second quarter of 2004 of
$1,310,000, or $.13 per basic and diluted share, compared with $969,000, or $.10
per basic and diluted share, in the second quarter of 2003. Total net sales for
the second quarter were $26,607,000 compared with $21,140,000 in the same
quarter of 2003. Product sales for the three months ended June 30, 2004
increased 25 percent to $26,288,000 from $20,975,000 for the similar period in
2003. Tooling sales totaled $319,000 for the second quarter 2004 versus $165,000
for the similar time period in 2003. Revenue from tooling projects is sporadic
in nature and does not represent a recurring trend.

         For the first six months of 2004, net income was $1,855,000, or $.19
per basic and diluted share, compared with $1,485,000, or $.15 per basic and
diluted share, in the similar period of 2003. Total net sales for the first six
months of 2004 were $50,848,000 compared with $50,684,000 in the first half of
2003. Product sales for the first six months of 2004 increased 26 percent to
$50,395,000 from $40,038,000 for the similar period in 2003. Tooling sales
totaled $453,000 for the first six months of 2004 versus $10,646,000 for the
similar period in 2003.

         "We are pleased with the recovery in many of the markets we serve,
particularly in the trucking industry, which has helped the company better
absorb its fixed cost," said James L. Simonton, president and chief executive
officer. "We have made significant process improvements at our Gaffney facility
and continue to aggressively pursue process improvements that should enable the
plant to return to normal operating levels by the end of the third quarter
2004," Simonton said.

         "Even with the continued across-the-board demand increases from the
markets we serve, we anticipate experiencing the normal third quarter seasonal
softness and its downward effect on third quarter earnings resulting from our
customers' planned vacation shutdowns," said Simonton.

         As previously announced, Core recently reached a labor agreement with
the International Association of Machinists and Aerospace Workers (IAM) at its
Columbus, Ohio manufacturing


                                       v




facility. The agreement, which extends until 2007, enabled the Columbus plant to
return to normal operations on August 16, 2004.
