Excessively fast screw wear of PET '2079851475616104452 machine
Fenómeno del problema
When processing glass fiber containing PET, the screw and barrel of the '2079851475616104452 machine wear severely, and their life is greatly shortened.
Análisis de la causa
Glass fiber is extremely abrasive to metal surfaces; the screw and barrel materials are not wear-resistant (not bimetallic treated).
Solución
Use bimetallic screws and barrels (surface hardness above HRC60); reduce glass fiber content; appropriately reduce processing temperature.
Conclusión clave
Reinforced PET processing requires wear-resistant special screws and barrels.
