Silicone Moulding

Reliable, Cost Effective, Versatile

Silicone Injection Moulding Process

Thormac has HSR silicone rubber injection moulding capability. We do this using DESMA vertical injection moulding machines.

The Process

  • Mill Softening and Catalyzation
  • Preparation of a Preform
  • Extrusion
  • Moulding
  • Vulcanization
  • Finishing

The heated, uncured silicone is injected into the mould using a large ram. This silicone is forced into the mould cavity the injection nozzle. As the silicone cools, it separates from the walls of the mould, while retaining the details and shape of the design. The press opens and the silicone part is released. It is then placed in an oven to cure.
