Automotive Liquid Silicone Rubber

In Sigma International’s Liquid Silicone Rubber Molding process, materials are precisely blended to mold end parts. This process requires special equipment that relies on a metered pumping device and an injection molding machine with a mixing device attached.

Liquid Silicone Rubber Molding starts with the two silicone components – A and B. These two components are mixed precisely at a 50/50 mixture. After they are combined, the mixture is pumped to the injection molding machines and the molding machine extruder rotates to build a shot. When the shot is built, the injection unit injects the shot into the mold where it sets.

Liquid Silicone Rubber Molding is best suited for small parts in the medical, automotive and industrial industries. Contact us to determine if your part is a right fit for this process.

Liquid Silicone Rubber can be used to make the following molded parts:

  • Pumps
  • Caps and stoppers
  • Membrane pumps
  • Spark plug boots
  • Electrical insulation
  • Bellows
  • Suction cups
  • Soft touch parts
  • Gaskets
  • Light pipes
  • Check valves
  • O rings
