Molded Rubber Parts Processes
Injection Molding
Injection molding is a manufacturing process accomplished by taking raw, uncured rubber and forcing it into a heated mold using a reciprocating screw. The material is formed and cured under heat and pressure, then removed to cool as a custom shape.
Compression Molding
Compression molding is defined by taking a pre-measured amount of raw rubber material that is placed into a heated open lower mold cavity. The top cavity is then forced closed, causing the raw material to flow through the shape of the mold. After curing, the mold cavity is opened and the shapes can be removed.
Transfer Molding
Transfer molding is a form of rubber production in which the raw material is measured, heated and then forced into chamber. A plunger is used to force the material into the mold using a system of runners and channels to thoroughly fill the closed mold. The mold is heated to cure the raw material. The mold is then opened and the molded parts can be removed.
