Custom Molded Rubber

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.

Liquid Injection Molding

A high-volume molding method where liquid silicone rubber is kept cool until it is forced into a heated cavity and vulcanized.

A custom molded rubber product or part is not a generic product or standard  off-the-shelf part. CSS, Inc offers many different elastomers  that have different results.
A lot of custom molded rubber products  may look the same, but poor quality or the wrong process or elastomer may  have results with an entirely different outcome. The product may fail over time due to temperature, fading, tearing, abrasions, chemicals or other factors.
