Exothermic Molding’s Mission is to provide the highest value Reaction Injection Molding services available.

Exothermic Molding achieves ongoing organizational excellence through certified adherence to the ISO Management System providing more and better services while improving jobs and business performance.

Exothermic Molding strives to produce quality parts, on time, combined with a consistent level of service that meets or exceeds our customer’s expectations.  We accomplish this using documented manufacturing procedures and a dedication towards improving our process.

ISO 9001:2015 sets out the criteria for a quality management system. It can be used by an organization, large or small, regardless of its field of activity.

This standard is based on a number of quality management principles including a strong customer focus, the motivation and implication of top management, the process approach and continual improvement. These principles help ensure that customers get consistent, good quality products and services.

Exothermic, one of the pioneers in the RIM Molding industry, was founded circa 1972 with a business plan to provide Reaction Injection Molded (RIM) parts to the medical, electronic, and lab instrument market. Since then Exothermic has expanded into many other applications and markets but remains committed to the RIM Molding process.
The company has grown from a garage based operation to the modern, eight-press, 10,500 square foot facility of today. Over the years many technological improvements have been made to the equipment and process.

Exothermic Molding is considered a state-of-the-art facility with modern computerized Programmable Logic Controlled machinery. This includes urethane metering units, an environment controlled, positive pressure spray booth with air make up and bake and cure capability, and modern CNC machining centers.

From the very beginning the Exothermic philosophy was to provide as much customer value as possible. As a result the company has always had painting and silk screening capability, which allows finished parts to go directly to the customer’s assembly lines. In addition, Exothermic often sources and sub-assembles other matching components to further reduce the customer’s cost.

RIM’s future is bright. Industrial Designers and Mechanical Engineers are discovering its great design flexibility and outstanding value.  As the benefits of RIM become more apparent, it is being recognized as a preferred manufacturing process.  Exothermic is at the forefront of RIM manufacturing, and no matter where the technology leads, the company will be there as it heads into its fifth decade.

RIM Injection Molding Company

For RIM molding, Exothermic Molding is the best I've worked with. They are very knowledgeable in their industry and this specific field. If you have a RIM product, I would recommend this company. They've always had excellent suggestions to improve machining capabilities and lower mold cost.
