How do you choose the right parallel twin screw barrel for a specific plastic extrusion application

Choosing the right parallel twin screw barrel for plastic extruder machine application involves considering several factors. Here are some key steps to help you make the right choice:

1.Understand the properties of the plastic material you will be extruding, such as its viscosity, melting point, and flow rate. This will help you determine the appropriate screw geometry, pitch, and length required for the application.
2.Determine the desired output rate for your extrusion process. This will influence the screw diameter and length needed to achieve the desired throughput.
3.Consider the desired quality and consistency of the extruded product. This will impact the selection of the screw configuration, as well as the barrel heating and cooling requirements.
4.Take into account the expected operating conditions, such as the temperature, pressure, and shear rate during the extrusion process. This will help determine the required material properties for the screw and barrel, such as hardness and wear resistance.
5.Evaluate the overall cost and durability of the screw and barrel. This will depend on factors such as the material used, the manufacturing process, and the expected maintenance and replacement costs.
6.Consult with experts in the field or manufacturers of twin screw extruders to get advice on the most suitable screw and barrel design for your specific application.

By considering these factors, you can choose the right parallel twin screw barrel for your plastic extrusion application and ensure optimal performance and efficiency.

Twin screw and barrel type: CINCINNATI, BATTENFELD, KRAUSSMAFFEI, BAUSANO, MAPLAN and AMUT model spares.
The screw of the series consists mainly of two parallel cylindrical screws, which rotate to the opposite direction. Parallel double screw rotational speed is low, less heat, shear stability of the materials in the barrel, uniform, screw of material conveying ability is strong, have good exhaust effect at the same time, is conducive to the stability of product quality.
The main applications: Includes PVC pipe & profile extrude, PP/PE sheet product.
