What Twin Screw Extruder Machine You Need ?

GS mach which is a manufacturing vendor, specializing in the twin screw extruder pelletizing line and spare parts, with high quality machine and competitive price.

WPC Wood Plastic Composites

Basic Formula

  • PP/PE/PVC compounding with wood fiber up to 65%, color masterbatch and additives


  • PP/HDPE melting temperature is more than 170℃, so it is necessary to feed wood fiber from the side feeder.

  • Wood fiber premix additives then feed into side force feeder. GSmach supply screw design to avoid over shearing but still good mixing without reducing the length of fiber.

  • For PVC window profile, no need to make compounding material into pellets, just cool down and crush it into powder.
