1 . Description


Screw element type for each function: Feeding, Melting, Mixing, Venting, Pressurization
Screw Configuration
means a structure composed of different combinations to achieve the desired performance,such as disperse, shear effect, solving the requirements of mixed materials as well as the production stability.
Depending on the nature of work being carried out,there are Intake Zone,Conveying Zone,Melting Zone, Natural Venting Zone,Mixing Zone,Vacuum Venting Zone and Metering Zone.
Different screw elements own different features in different extrusion process,we should choose and design the right screw elements based on different extrusion status in order to optimize the overall comprehensive performance in the extrusion process.

3 . Comparsion of the output (LDPE)

Pressure is generated if resin passes over the barrier, forcing any air in the melted resin back to the feed side and effectively preventing the intrusion of air bubbles on the sub flight side. This is highly effective with resins that generate bubbles such as PS, PA, PET and EVOH.

4 . Parallel twin screw and barrel application




Intake &Conveying Zone

For feeding and conveying the raw materials to the extruder

Melting Zone

For heating the material to make some or all materials melt

Natural Venting Zone

For removing the volatile matter and moisture

Mixing Zone

For mixing the materials fully

Vacuum Venting Zone

For completely ruling out the volatiles and water to reach the desired state

Metering Zone

Metering Zone

Bimetallic Treatment of Screw

The bimetallic screw for extruder twin screw is a kind of screw spray welding a 2~3mm-thick alloy coat on the screw flight of output area for the screw . The Bimetallic treatment has excellent corrosion resistance, abrasion resistance and high working temperature. And its useful service life is greatly improved contrast to the common nitrided screw.
