Rubber Moulding

Compression Moulding is one of the simplest and least expensive ways to produce moulded rubber parts. While it is not typically recommended for complex parts requiring tight tolerances or flawless finishes, it is very cost effective method for manufacturing lower volume items.

Transfer Moulding is very similar to compression moulding except that the material is pushed or "transferred" into the cavity by a piston instead of being directly placed into the mould as it is in compression moulding. The added control in this process allows it to produce more complex parts with tighter tolerances and more consistent surface appearance. On the downside, the tooling is typically more expensive and it tends to operate at slower speeds than compression or injection moulding.

Injection Moulding rubber is very similar to injection moulded plastic. The process is the best choice for complex high volume products that require tight tolerances. The piece prices for injection moulded rubber parts are often very competitive if the volume justifies the more expensive tooling and set up charges.

Commonly moulded materials include Silicone, EPDM, Nitrile (NBR), Neoprene®, Hypalon®, SBR, Viton®, and Natural Rubber. Please refer to our materials chart or consult your StockCap sales engineer for determining the best material to use in your application.
