Here are some of the ways we assist our customers:
PROPRIETARY SEAL DESIGN SOFTWARE
With the aid of our sophisticated proprietary seal design software and 3D modeling software, we can design virtually any seal very quickly, thus reducing design and development cost. From design to prototype takes only a few days.
KNOWLEDGE OF MATERIALS
Selecting the right material for the application is the first and most critical step in designing a custom seal.
COS engineers understand advanced sealing materials. We have an ongoing commitment to use the highest grade of materials to give our customers maximum seal durability. We partner with leading edge raw material developers to make new and advanced materials available to our customers in the seals we make for them.
Our Custom Engineered Seals are available in a wide range of sizes and materials. Our materials include: Polyurethane; Nitrile; Viton®; H-Nbr; water resistant (hydrolysis resistant) Polyurethane; high-performance Polyurethane; Silicone; FDA materials; Aflas®; Kalrez®; EPDM; Hytrel®; UMWPE; Tefzel®; Peek and a range of proprietary filled Teflon® (PTFE). Many specialist Duralast™ and Permachem™ elastomers as well as Duraloy™ Engineering Plastics were developed to match real world applications, and on many occasions we have developed a special grade to solve a customer’s current application difficulty.
