Glass Fibre internal voids
Sorun Belirtisi
Glass Fibre products have 1-3mm voids inside, concentrated at the thick-wall center
Neden Analizi
insufficient holding, thick-wall center not compacted; gas entrapment cannot be vented; moisture in raw material vaporizes
Çözüm
1) increase holding pressure 60-80MPa for full compaction; 2) increase mold venting; 3) fully dry the raw material
Temel Çıkarım
internal voids are caused by insufficient holding and gas entrapment; high holding pressure and venting are key
