PA66 dynamic mold temperature technology
Sorun Belirtisi
Warpage and weld lines of thin-walled precision PA66 parts are hard to balance, conventional mold temperature is caught in a dilemma
Neden Analizi
Constant mold temperature cannot balance filling and cooling: low temperature benefits cycle but worsens weld lines and stress; dynamic mold temperature rises to 120℃ during the filling stage then cools rapidly, balancing both
Çözüm
①Evaluate dynamic mold temperature control DMTC for high-precision thin-walled parts; ②mold surface heating during filling stage improves flow and weld lines; ③rapid cooling during cooling stage preserves cycle
Temel Çıkarım
Dynamic mold temperature is an advanced means for precision PA66 parts; warpage can be reduced by 60% while cycle is controllable, suitable for high value-added products; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
