Molded Silicone Foam and Sponges

Offering rubber compression and injection molding services, Cascade Gasket specializes in Boeing Aerospace Certified Rubber Compression molding. We mold pieces from small parts to large components, enabling us to compress mold parts up to 144” long and 48” wide at 100 psi. Additionally, we can use compression molds with up to 100 cavities to manufacture our custom gaskets and other parts. Besides organic rubber (from 15 to 80 durometer), we also work with silicone compounds as well as polypropylene, polystyrene, and polyurethane. Cascade Gasket is ISO 9001:2008, AS-9100, and AS-9102 certified.

Our injection molding capacity runs from one to thirty cavities, with molds up to 17.25” between bars by 11” and a 1000 cc shot size. Tolerance for all molding processes is to +/- 0.005”. Our facility also offers product development and mold making services. Lead times are quoted on a job by job basis, with emergency and rush service available. We are pleased to serve, in addition to aerospace companies, the train, bus, maritime and communication industries.
