Screw Wear of PC '2079851475616104452 Machine
Problem Phenomenon
When processing glass fiber reinforced PC, the screw and barrel wear severely.
Cause Analysis
Glass fiber has high hardness and is strongly abrasive to the screw, and the screw material is not wear-resistant.
Solution
Use bimetallic or tungsten carbide coated screws; reduce the glass fiber content.
Key Takeaway
PC reinforced materials are a test of equipment wear.
