Rubber Molding

Western Rubber and Supply custom molded rubber products and custom molded rubber parts.

Why compromise by trying to make a standard part fit your custom application? Our custom molding services, including both rubber and silicone molding, put you in the driver’s seat by allowing you to create the product that best suits your design. We can custom mold products from a variety of polymers, including Silicone, Neoprene, EPDM, Fluoroelastomer, SBR, Nitrile, Fluorosilicone, Natural Rubber, Viton® and thermoplastic vulcanizates. We can deliver the following:

  • Large format
  • Micro-molding
  • Molded sponge
  • Rubber to metal bonding
  • Prototypes to large production
  • Quick turn capabilities
  • High precision, high tolerance parts
  • Physical and chemical testing available

Contact one of our professionals or send us a drawing. We can custom mold rubber to your exact requirements using one of the processes described below:

Compression Molding

This molding method involves applying pressure and heat to a material inside a mold cavity until it has cured. It is generally more economical than other molding processes and is suited for producing curved or intricate parts.

Injection Molding

This process is more complex than either compression or transfer molding, and it involves forcing molten material into a mold cavity with a ram or screw-type plunger. In this method, the mold halves are clamped before the material is injected.

Transfer Molding

This is a process similar to compression molding where material is forced into a mold cavity until it cools and takes on the shape of the cavity. One major difference is that a plunger forces the material into the cavity through a funnel, or sprue.

Liquid Injection Molding

This is a high-volume process that uses liquid silicone rubber. In this method, the material is kept cool until it is forced into a heated cavity and vulcanized.
