SCREW TYPES

BASIC 3-ZONE SCREW

Universal screw geometry, allowing processing of a wide range of polymers.

Application:

  • Suitable for processing a wide range of materials
  • Easy to change colour and material
  • Suitable for processing the material filled by long glass fibre
  • Suitable for processing material with abrasive and corrosive fillers

BARRIER SCREW

Special design of the barrier screw allows for higher efficiency in melting and homogenization of the material.

Application:

  • Reduces plasticization time by up to 40%
  • More efficient temperature control
  • Possibility to use lower back pressure
  • Ability to process a wide range of polymers with different viscosities
  • The design is not suitable for processing materials that are inclinable to overheating (e.g. POM, PVC, PMMA, PC)

BARRIER SCREW WITH MIXING ZONE

The special design of the barrier screw enables higher efficiency in melting and homogenization of the material and thanks to the added mixing zone higher efficiency of mixing the material with the dye.

Určení:

  • Much better colouring of the material
  • Easy change of material and dye
  • Reduces plasticization time by up to 40%
  • More efficient temperature control
  • Possibility to use lower back pressure
  • Ability to process a wide range of polymers with different viscosities
  • The design is not suitable for processing materials that are inclinable to overheating (e.g. POM, PVC, PMMA, PC)
  • Not suitable for processing long glass fibre material
