Liquid Silicone Rubber Injection Molding Process

The liquid silicone rubber injection molding process delivers two-part liquid silicone directly into a mixer, which is then injected into the mold cavities through a runner and gate system. The silicone is held under pressure and heated until it is cured. Silicone rubber is the optimal material for liquid injection molding, which is able to produce precision parts as well as complex over-molded assemblies. The process is also suitable for adding pigment to produce colored components.

Flexan engineers consult with each of our clients to recommend the optimal molding process for the application at hand.
