When the material moves forward along the screw, it experiences changes in temperature, pressure, viscosity, etc. This change is not the same throughout the entire length of the screw. According to the changing characteristics of the material, the screw can be divided into a feeding section, a compression section and a homoge0nization section.

How to solve the wear problem of the compression section or the melting section without pulling out the screw frequently?

1. What is the screw L/D ratio? 2. The advantage of increasing the L/D ratio 3. How to choose the L/D ratio?
