Problema e solução
Respostas práticas para os desafios comuns dos materiais plásticos
Snake-like curved lines appear on the product from the gate
Differences in molecular weight, additive content, etc. between batches affect processing stability
Low-temperature performance changes of PA-type materials require evaluation of applicability
Equipment parameters not matching material characteristics affect processing quality
Compression molding is used to reduce warpage and internal stress but the parameters are set improperly
Unreasonable temperature settings in each zone affect plasticization and extrusion quality
Mold temperature differences in different areas affect product quality
Rear zone temperature deviating from the recommended value affects plasticization
Improper annealing treatment, residual stress not eliminated or product deformed
Large shrinkage difference between the melt flow direction and the perpendicular direction
