Custom Rubber Molding

Molded Rubber Parts Custom Designed And Supplied To Your Specific Needs

If you can imagine it, we can mold it. When it comes to molded rubber parts, Genesis Rubber can supply high quality parts with tight tolerances, custom designed to fit your application. We can also work with your existing molded part, and supply you with a reverse engineered part. No part is too complex and we can color match your part to pantone and RAL numbers based on your requirements.


Our molding capabilities include: Compression molding, transfer molding, and injection molding, as well as rapid prototyping.

Molded Silicone

Compression Molding

An uncured elastomer preform is placed into a heated mold. The rubber is compressed between top and bottom plates (generally 2 plates but may contain 3 or more depending on part complexity and configuration) and the rubber part is vulcanized (cured) with heat and pressure (from compression).


Transfer Molding

An uncured elastomer is placed in a “transfer pot” located above the mold and the cavity. A piston transfers the uncured rubber into a pre-heated mold through a sprue, runner and gate system. The rubber part is vulcanized through heat and pressure.


Injection Molding

The preheated mold is closed by a press which applies pressure to keep the mold closed during the injection and curing cycles. An uncured elastomer is injected into a heated mold by a large ram or screw. The elastomer is forced into the mold and its cavities through a runner, sprue and gate system.
