Compression Molding

Rubber compression molding forms uncured rubber into a desired shape. First, the elastomer is pre- heated until pliable and then put into an open mold cavity. Closing the mold forces the rubber to fill the cavity, where the elastomer is keep under heat and pressure until cured.

The advantages of compression molding include:

  • Lower tooling costs
  • Small production runs
  • Suitable for larger, heavier parts

Injection Molding

Injection molding feeds uncured plastic from a hopper into heated barrel. The material is then pushed by a screw-type plunger into a heated chamber. This material flows through a gate and runner system into mold cavity. The mold remains at the proper temperature until the plastic is cured.

The advantages of rubber injection molding include:

  •  Quicker cycle times
  • Custom shapes with little flash
  • Support for wide range of durometers

Rubber-to-Metal Bonding

Rubber to metal bonding is a means by which rubber is mechanically bonded to a metal insert during the molding process. Rubber to metal bonding is typically used for the isolation of noise and vibration in automotive and engineering applications. Rubber to metal bonded parts can be used in valve assemblies, rollers and shafts. Other applications that employ rubber to metal bonded products include mounts for motors, general rubber to metal bonded parts for the rail and transport industries and locomotive suspension parts.

The advantages of rubber-to-metal bonding include:

  •  Combines of the flexibility of rubber and the stability of a metal
  • Finished parts are exceptionally strong and durable
  • Reduce the number of parts in an assembly
