Multi-component injection molding

Starlim North America is specialized in the mass production of silicone parts. We also make multi-component injection molding products (also called 2K, which stands for 2 components). One of the components however must be silicone. starlim//sterner connects the other component using a safe and reliable process.

We can combine these components:

  • Silicon-Thermoplastic material
  • Silicon-Metal
  • Silicon-Glass
  • Silicon-Silicon, e.g. having differing Shore A hardness or colors.


Both materials are combined with one another by chemical or mechanical methods.
First, component 1 is injected (thermoplastic material, metal, glass, silicone) or placed in the mold. Next, the item is overmolded with silicone. This is the method of producing compound parts.

Popular multi-component products are items such as steering wheel switches for cars, jet-formers for shower heads, door-bell key or the hydraulic brake systems for kitchen drawers, doors and flaps.
