Red Star specializes in overmolding for Orthopaedic instruments

Overmolding is a process wherein plastic resin is molded around a part made of another resin without removing the part from the molding press. This may be accomplished either by use of a robot, or a rotary platen within the molding press.


Typically, 2 different resins with different physical or chemical properties are used to create an assembly complete from the molding press in a single process.

Some common examples are:

  • Finished plastic parts with multiple colors

  • Instrument handles or controls with a soft-grip surface molded over a rigid base

  • Mechatronic assemblies using resins with different shrink rates to create movable multi-part assemblies

  • Valves and seals requiring a low durometer sealing surface on a rigid structural base
