Compression and Transfer Molding is accomplished by placing a pre-weighed amount of rubber in a matched metal mold and closing the mold. The heat and pressure cause the rubber to liquefy and flow into the voids in the tool where it chemically reacts and hardens into the final shape. Very large shapes can be molded in compression presses.

Process Characteristics
Part Cost - low to moderate Tooling Cost - high Production Rate -high Tolerances are held tightly using injection molding No trimming is required Wide variety of rubber compounds give varying costs and material properties.
