Screw Configuration

It 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.

Screw elements are convenient interchangeability by agile combination, which can fulfill efficient self-cleaning, transmission, compounding, pressure-forming, etc. They are made of high tool speed W6Mo5Cr4V2, or anti-corrosion steel 38CrMoAlA by special treatment.

Assembled together, they will become twin screw which are essential and key part of extruders for material to transmission, shearing and plasticization.
