Perfluoroelastomers and frp chemical resistance

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.

Dia.Com Has Been Certified to ISO/ TS 16949

Dia.Com's Quality Systems are certified to the ISO/ TS 16949:2002 Quality Management System, an International standard developed to supersede the QS-9000 Quality System. ISO/ TS 16949:2002 uses a process approach when developing, implementing, and improving the effectiveness of a quality management system, to enhance customer satisfaction by meeting customer requirements.

History

Dia•Com is a leading international provider of innovative, cost-effective molded diaphragm solutions critical to the operation of essential systems and equipment in industrial, automotive, aerospace, medical instrumentation, and food and water processing applications. The company's reputation for excellence is based on superior quality in the design, manufacture and application of its high-performance, state-of-the-art, fabric-reinforced and homogeneous elastomeric diaphragm seals.

The company was founded in 1983 as a supplier of custom and standard diaphragm seals known for reliability and dependability. Today, Dia•Com, with worldwide corporate headquarters in Amherst, New Hampshire, focuses on forming strategic customer partnerships critical to the development of unique, technologically superior design solutions linked to its customers' success. As an extension of its customers’ design teams, Dia•Com offers a broad range of custom diaphragm solutions that are “designed for manufacturing,” and as a result, are more comprehensive, robust and cost-effective than competitive products.
