PPS Mold Temperature Management and Crystallization
Sorun Belirtisi
Insufficient product crystallinity with poor performance or excessive crystallization causing warpage.
Neden Analizi
PPS mold temperature is usually 120~150°C (some 150~200°C); low mold temperature causes insufficient crystallization and poor strength and heat resistance, while too high or uneven mold temperature causes warpage.
Çözüm
①Control mold temperature at 120~150°C and adjust by grade; ②high mold temperature improves crystallinity and dimensional stability; ③balance mold temperature distribution; ④detect cavity temperature.
Temel Çıkarım
Mold temperature is the master switch of PPS crystallinity; high and uniform mold temperature is the premise for its performance.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
