Rubber Molding Processes

Molding Processes

Injection Molding

Injection molding is a manufacturing process accomplished by taking raw, uncured rubber made of strips and forcing it into an injection chamber using a rotating screw. The material is then forced from the chamber into the mold and cured with time under heat and pressure.

Compression Molding

Compression molding is accomplished by taking a pre-measured amount of raw rubber material that is placed into a heated open lower mold cavity. The lower mold cavity is then forced to close against the upper mold cavity, 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 a chamber. A plunger is used to force the pre-measured material into the mold and cured with time under heat and pressure.
