Extruding - Continuous Cure - Autoclave Cure

Autoclave Cure. Autoclaving rubber permits us to make large or custom formed parts. The rubber is extruded onto round pans or long trays. It is then placed into the autoclave, a large pressurized and steam-heated vessel, where it will be cured. If a customer wants it with a bend - we ship it with a bend.
