ASA poor venting trapped air
Sorun Belirtisi
ASA high-speed filling shows burnt marks and insufficient filling at product end; after reducing speed, surface quality worsens again, falling into a dilemma.
Neden Analizi
ASA recommends high injection speed for the best surface, but when mold venting capacity is insufficient, high-speed filling compresses air with nowhere to escape; burnt and short shot appear simultaneously when venting is poor.
Çözüm
①Strengthen mold venting according to high-speed process requirements: deepen and densify vent grooves; ②focus venting on end convergence area; ③regularly clean oil contamination in vent grooves; ④vacuum venting to cooperate with high-speed process if necessary.
Temel Çıkarım
ASA high-speed process and venting capacity are bound conditions; solve venting first, then enjoy the surface and weld line benefits brought by high speed; venting design is checked according to high-speed filling.
