Dia•Com- Fabric-Reinforced and Homogeneous Elastomeric Diaphragms

Corporate Headquarters

Dia•Com's International Corporate Headquarters was specifically designed and constructed for state-of-the-art molded elastomeric diaphragm design and manufacturing. The 30,000 square foot facility, completed during the spring of 1994, had detailed planning and consideration given to material flow, HVAC and electrical systems as well as future expansion.

Microprocessor-Controlled Production Presses

Microprocessor-Controlled Production Presses were designed specifically for the production of fabric-reinforced and homogeneous elastomeric diaphragms. Our new production presses are built with high strength components. The microprocessors closely control the vulcanization process, thus assuring precise, repeatable control of the molding process. The result is high quality, low cost diaphragm production. Dia•Com utilizes unique compression and transfer molding processes to maximize efficiencies and insure the dimensional integrity of each part.
