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.

GSmach can provide extruder for hot melt extrusion (HME).

Basic Formula

  • EVA base material: EVA, rosin, wax, stabiliser and additives
  • TPU base material: TPU (main) + other polymers (ABS/GPPS/EVA) + additives

Process

  • Depending on the viscosity of the melting material, two processes are available:
    1) If the viscosity of the material is less than 4000 CPS, it is best to use a drop distiller system. The same system can be used for any additive material with a melting temperature below 100 degrees, e.g. waxes, additives.

  • Distributor -> belt cooling system -> bucket elevator -> packaging system

Hot Melt Extrusion Process
  • If the viscosity of the raw material exceeds 4000 CPS, an underwater pelletizing system is preferable.

  • Feed -> Feed -> Twin Screw Mixing -> Melt Filter -> Melt Pump -> Underwater Pelletizer -> Dewatering -> Classifier -> Conveying and Storage
