Plastic Component Capabilities


KOK applies the following manufacturing technologies in support of component performance, repeatability, and OEM production requirements:

Multi-Material (3-Component) Molding

KOK integrates multiple materials, such as plastics and elastomers, within a single molded component to meet complex functional requirements including sealing, vibration damping, and structural support.

Typical Applications

  • Recreational vehicle components, including snowmobile support (idler) wheels
  • OEM assemblies requiring integrated flexibility and rigidity
Plastic Injection & Compression Molding

KOK designs and manufactures injection and compression molded plastic components with controlled tolerances and material properties, supporting applications that demand heat resistance, mechanical strength, and long-term dimensional stability.

Typical Applications

  • Automotive systems
  • Recreational and mobility platforms
