PP Shrinkage 1.0-2.5
Sorun Belirtisi
PP shrinkage 1.0-2.5% is high; crystalline material; dimensional accuracy challenge.
Neden Analizi
PP shrinkage 1.0-2.5%; semi-crystalline material has large shrinkage; directional differences; post-shrinkage; mold design compensation; process influence; dimensional accuracy challenge.
Çözüm
①Design the mold per 1.0-2.5%; ②Consider directionality; ③Evaluate post-shrinkage; ④Process stability; ⑤Actual measurement verification.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
PP's high shrinkage is a characteristic of crystalline materials; directionality and post-shrinkage are challenges; mold compensation and verification are equally important.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
