What is silicone compression molding?

Compression molding is the process of placing un-vulcanized LSR material into the cavity of each half of the mold. The mold is then assembled, placed into a heated compression molding press, and cycled. Silicone is vulcanized through this process and a part is formed. While this molding process itself is somewhat slower than injection molding, it does yield quick turns on prototype or R&D phase parts as well as less costly tooling upfront.

• Runs to create a variety of parts, including gaskets, seals, and intricate medical components.
• Shortened lead times
• Less expensive tooling
