Injection Compression Molding (ICM) involves injecting plastic melt while the mold is slightly open and then quickly applying clamp tonnage to complete the filling of the cavity.
Injecting plastic into a partially closed mold
This technology is especially attractive for molding parts such as thin wall lids, large diameter overcaps, and shallow draw containers. StackTeck partners with global leading molding machine suppliers to offer integrated approaches to new applications.
ICM features and benefits:
  • Typical part weight reduction of approximately 20%

  • Technology allows for molding parts with lower MFI resins

  • Dramatically lower filling pressure

  • Sustainability option suitable for high volume lid applications

  • Lower energy usage - reduced melt temperatures and lower injection pressures

  • Mold precision and alignment is critical

  • Machine requires integrated control of injection and clamp timing
