Single-screw plastic extrusion machine „Standard Line“ with Co-extrusion

We count on the single-screw extrusion technology for our plastic extrusion lines. With our long-developed and unique feed zone, up to 100% recycled plastic (e.g. PET-flakes or rHDPE) can be processed. The specially designed screws of our plastics extrusion machines, which are calculated down to the smallest detail, guarantee fast and, above all, gentle melting of the material.

This guarantees a high quality of the melt.

We also have many years of experience in the manufacturing of wide nozzle dies. Each die is calculated and designed in-house. Therefore, we are very flexible and can adapt them to any customer requirement.

In our portfolio we have:

  • internal / external deckled dies
  • with / without automatic die
  • with / without restrictor bar

Single-screw plastic extrusion machines with direct drive and high-performance energy control means significant energy-saving options.Proven single-screw extrusion solutions also mean:

  • Small number of rotating parts
  • Low friction, abrasion and wear
  • Low shearing stress on parts and materials
  • Gentle material melting process
  • High IV retention
  • Low energy consumption
Plastics extruder machine by diamat for forming PET-sheets from up to 100 % regrind.

Extrudable plastics

Our plastic extruder machines can mix components to the gram and melt them at exactly the right temperature.

Therefore our plastic extruders are able to extrude a large variety of plastics including:

  • polypropylene (PP)
  • polyethylene (PE, also known as polyethene or polymethylene)
  • high-density polyethylene (PE-HD)
  • polyurethane (PU or PUR)
  • thermoplastic polyurethane (TUR)
  • polystyrene (PS)
  • acrylonitrile butadiene styrene (ABS)
  • ethylene vinyl alcohol (EVOH)

and various polyesters like polyethylene terephthalate (PET – including recycled flakes) or amorphous PET (A-PET).
