PET mold temperature 70-80℃
Sorun Belirtisi
PET engineering injection molded parts warp and deform, or their heat resistance fails to meet the standard due to insufficient crystallization
Neden Analizi
PET injection mold temperature affects the crystallinity: low mold temperature leads to insufficient crystallization, poor product heat resistance, and post-crystallization deformation; an injection mold temperature of 70-80℃ combined with a cooling mold temperature of 40-50℃ can balance crystallization and cycle
Çözüm
①Mold temperature 70-80℃ in the injection stage; ②mold temperature 40-50℃ in the cooling stage; ③for products with high heat resistance requirements, ensure sufficient crystallinity; after adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
PET mold temperature is managed in stages; high temperature in injection ensures crystallization and low temperature in cooling ensures the cycle, and the two-stage combination is the standard practice for engineering parts; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
