Single-screw extruders

Single-screw extrusion is one of our core competencies

  • Our extrusion systems are based on the sophisticated, well-known Oerlikon Barmag constructions. There are more than 15,000 extruders currently in operation.
  • Our product range includes small feed extruders with 30-mm screw diameters, large extruders with 360-mm screw diameters and large cascade extrusion systems.
  • The portfolio of processable polymers ranges from PE/PP polyolefins, polyamides and polyester all the way through to special polymers such as PEEK and EVOH.
  • Among other things, our machines are used in film extrusion systems (main and co-extruders for BO-PET, BO-PP, BO-PA, PP and PET cast films), spinning systems for POY, FDY and IDY made from PET, PP and PA and for various special applications.

 

Single-screw extruders for processing PET, PA, PP etc., with screw diameters of 30 - 200 mm, cylinder lengths 24, 30 and 33 L/D, i.e. for fiber spinning lines, film lines etc.
