Die Cut Gaskets

Stockwell Elastomerics offers custom die cut gaskets, using steel rule die cutting on silicone rubber and other elastomers, for fast, efficient and economical gasket production.

Kiss cut progression strips on liner Kiss Cut Gaskets

Kiss cut gaskets are supplied on a roll where the gasket can easily be removed from the paper backing. Kiss cutting is a process where the gasket material is cut but the adhesive backing (paper liner) remains intact. The surrounding material is removed leaving just the kiss cut gaskets on the paper liner.

Molded Gaskets

Stockwell Elastomerics liquid injection molds silicone rubber from 10 to 70 durometer and compression molds specialty parts such as EMI gaskets. Silicone injection molding is a custom gasket manufacturing process that offers relatively low cost molds as compared to plastics. Short cycle times and in-house cryogenic deflashing make molded parts feasible in modest volumes.
