Customer Reviews
Reasonable Price, Good Service and Good People. we are very satisfied with their product. The performance of it is much better than we have expected

—— Mr.Danny Kwon

excellent service. The technicians are all very friendly and responsible. I would definitely recommend this seller to anyone who wants to buy machine.

—— Mr. ShiRong

I cooperated with Friend Company 5 years already, now i'm 72 years old, hope when i'm 82 years old, still purchase machine from them!!!

Application

  • Concerning our Extruders and Extrusion Lines you can rely on an unobstructed production. Our machine conception with direct drive and barrier screw providesextremely energy-saving Extruders of low maintenance requirements.
  • esde Single Screw Extruders are distinguished by their high output achievements on a low temperature level thus preventing the macro molecules from degradation and cross-linking processes. For melting the plastic material our Extruders receive the necessary heat almost exclusively from the motor. This heat is used in such an efficient way that the heating/cooling system on the barrel hardly requires operating.

Features

  • For plastic processing, extrusion has been used from the start. First to convey PVC and polyethylene, later also for engineering plastics.
  • The length of a screw is expressed as the ratio between diameter and length.
  • Since the emergence of crystalline engineering plastics, the length of the screws had to be increased.
  • The feed section is the part of the screw where the unmolten polymer enters into the barrel. The rotating screw moves the material along the heated barrel where it starts to melt.
  • In the compression zone, gases like air and volatiles like moisture, are being removed. In the compression zone, the flight depth decreases and gases are pushed back into the direction of the hopper.
  • Finally, the material enters the metering section. In this section, pressure is generatedwhich enables the material to be conveyed into the shaping area, like feed block or film die.
  • The compression ratio of the screw is the ratio between the flight depth of the feed section and the ratio of the metering section.
  • Most screws have a flight helix that is equal to the diameter of the screw.
  • Compression
  • Until the granules are molten, with every screw rotation, the material will be conveyed 1 speed. What has been conveyed is a mixture of roughly 50 % solids and 50 % air.
  • Without compression section, the molten material behaves like a foam. In the compression section, the volatiles are pushed back into the direction of the hopper.
  • The length of the compression section depends on the polymer to be extruded. The extreme example of PVC, the compression section comprised the full length of the screw. For crystalline polymers a very short compression section is recommended.
  • Mixing
  • All single screw extruders show some mixing effect, although very limited. For the proper dispersion of additives like stabilizers, antiblock agents, etc., mixing elements are being used.
  • There are various types of mixing sections, like Maddock, pineapple or pintype mixing elements.
