Rubber Transfer Molding Process

Transfer molding begins with pre-formed uncured rubber that is placed into the transfer pot of a closed molding system. The ram/plunger then distributes the rubber into the cavities to be shaped into the part, which is then cured by the application of pressure and heat for a specified time period. Transfer molding can be used for highly complex part geometries and precision applications, as well as over-molding. The process is suitable for molding parts with traditional organic black rubber as well as pigmented materials.

Flexan engineers consult with each of our clients to recommend the optimal molding process for the application at hand.
