CORE MATERIALS ANNOUNCES NAME AND STOCK SYMBOL CHANGES

COLUMBUS, Ohio - September 3, 2002 - Core Materials Corporation announced today
that it has officially changed its name and trading symbol. The company's new
name is Core Molding Technologies, Inc., and its new trading symbol, effective
September 3, 2002, is "CMT." Shareholders approved the name change August 28,
2002. The stock will continue to trade on American Stock Exchange. The company
also introduced a new logo as part of the change.

          "The company has evolved since its formation in 1996, especially with
the addition of our Mexico facility. The new name better reflects who we are
today and, more importantly, where we are headed," said James L. Simonton,
president and chief executive officer. "We took the opportunity to change our
name to correspond to an offer from another company to acquire the rights to use
the CME stock symbol. The timing of the offer worked well for us."

         Prior to last year, Core Materials was primarily a compression molder
of fiberglass reinforced plastic products. In October 2001, three additional
molding processes were added to the portfolio as well as a third strategically
located manufacturing site in Mexico.

         "The name Core Molding Technologies defines us as a provider of molding
solutions," explained Simonton. "I think it gives our customers and the
financial markets a better idea of what we do while also allowing for the
potential expansion into other complementary molding processes and technologies.
The old name may have implied that we were a supplier of materials when we are
primarily a manufacturer of molded products."

         Simonton said the company plans to leverage the new name and symbol
through a promotional campaign and investor targeting initiative. "I hope the
name change and the related promotional campaign convey our strong optimism
about the future," said Simonton. "This is a different company today. We've
added a third plant in Matamoros, Mexico. We continue to pursue operational
excellence using a combination of Lean Manufacturing and Six Sigma approaches.
We've added new customers in auto aftermarket and truck. We've expanded



                                       iv



beyond compression molding to include spray up, hand lay up and vacuum assisted
resin infusion molding processes."

         He added, "We've also delivered two quarters of positive financial
results despite the current economic weakness, and we are well positioned for
the upturn when it comes."

         Core Molding Technologies, Inc. is a compounder of sheet molding
composites (SMC) and molder of fiberglass reinforced plastics. The Company's
processing capabilities include the compression molding of SMC, vacuum assisted
resin infusion molding, spray up and lay up processes. The Company produces high
quality fiberglass reinforced, molded products and SMC materials for varied
markets, including medium- and heavy-duty trucks, automobiles, personal
watercraft and other commercial products. Core Molding Technologies, with its
headquarters in Columbus, Ohio, operates plants in Columbus, in Gaffney, South
Carolina, and in Matamoros, Mexico.
