Severe screw and barrel wear
Sorun Belirtisi
A new screw shows obvious wear after only a few months of service, with clearance exceeding the standard
Neden Analizi
Glass fiber has extremely high hardness (Mohs 5-6) producing abrasive wear; at high temperature the metal surface hardness decreases, aggravating wear; when glass fiber content exceeds 30%, wear accelerates
Çözüm
Use bimetallic screw and barrel (tungsten carbide or boronized surface); regularly test the screw-barrel clearance (at least once a year); control the glass fiber filling amount ≤40%
Temel Çıkarım
Abrasive wear of equipment in LGFPP processing is a persistent engineering and technical challenge
