Par 4 Plastics specializes in multi-shot injection molding as well as 2-shot plastic injection molding. 2-shot plastic injection molding is an efficient and cost effective method for molding custom plastic parts with two or more plastic resins or colors in one operation.

In multi-shot and 2-shot custom plastic injection molding, plastic polymers from two or more injection units are applied through independent nozzles on one plastic injection molding machine to produce custom plastic parts such as soft-grip handle inserts, multi-colored parts, dashboard or instrumentation, or parts with molded seals, flexible hinges, or movable components.

The multi-shot and 2-shot plastic injection molding technology enables:

  • Multi-color, multi-material and multi-component parts
  • New and wider range of designs
  • More complex parts and reduced cost
  • Production, handing and assembly efficiencies and savings
  • Reduction of multiple and secondary operations
  • Lower part cost
  • Enhanced product features and appeal, including tactile, ergonomic and aesthetics
  • Improved part and end use product integrity and quality
  • Elimination of secondary process for logos, graphics and text

With multi-shot and 2-shot plastic injection molding, you get the integrated functionality, multiple colors and materials, molded graphics and soft touch layers over rigid components you want, while reducing productions steps, time and cost!
