Excessively fast screw wear of PET '2079851475616104452 machine
ظاهرة المشكلة
When processing glass fiber containing PET, the screw and barrel of the '2079851475616104452 machine wear severely, and their life is greatly shortened.
تحليل الأسباب
Glass fiber is extremely abrasive to metal surfaces; the screw and barrel materials are not wear-resistant (not bimetallic treated).
الحل
Use bimetallic screws and barrels (surface hardness above HRC60); reduce glass fiber content; appropriately reduce processing temperature.
الخلاصة الأساسية
Reinforced PET processing requires wear-resistant special screws and barrels.
