Here we’d like briefly introduce 11 Important Principles of Plastic Extrusion as follows:

1. Mechanical Principles

2. Thermal principle

3. deceleration principle

4.The feed serves as a coolant

5. In the feed zone, stick to the barrel slide screw

6. The maximum cost of materials

7. The energy costs are relatively unimportant

8. The pressure is very important end of the screw

9. Output = final displacement +/- pressure stream and leak threads

10. The shear rate viscosity plays a major role in the

11. Motor and cylinder opposition, the opposition and the motor cylinder
