Rubber Compression Molding is the process of taking rubber compounds or mixed raw material and making “pre-forms'' in the shape of the end product and loading them, typically by hand, into an open mold. The mold is closed, the rubber cured, and then demolded—typically by hand. Compression molding is different from transfer molding because the rubber is put directly into the cavities, then compressed rather than being compressed in the pot then transferred into the cavities.
