PCR HOT RUNNER MOLDS
Molding plastic products with recycled resin is a growing, acceptable market solution to support meeting sustainability targets.
Optimally balanced hot runner manifolds for even part to part filling conditions

Molding plastic products with recycled resin is a growing, acceptable market solution to support meeting sustainability targets.  However, using PCR poses challenges in the molding process which must be addressed.  StackTeck’s team of engineers and process technicians support customer PCR molding initiatives with PCR targeted mold technologies and process controls.

Challenges include:

  • Melt Flow Index (MFI) variability resulting in narrow molding windows

  • Foreign contaminates contained within PCR regrind, high maintenance needs

  • Physical part qualities and variable shrinkage rates of PCR plastic parts

  • Process control and scrap management practices


StackTeck Hot Runner Mold Solutions:

  • Optimally balanced hot runner systems using innovative diffusion bonded technology

  • Reduced maintenance through in-the-press serviceability of mold components

  •  

  • Wear prevention using protective coatings and abrasion resistant materials

  • Prototyping services for part and shrinkage evaluation

  • Pressure monitoring systems through engineered cavity sensor technology
