PA66 vent groove 0.025mm
Sorun Belirtisi
Burnt and gas-trapped product ends, and flash appears after deepening the vent grooves
Neden Analizi
PA66 melt viscosity is low, and the overflow flash value is about 0.03mm; vent groove depth exceeding 0.025mm allows melt to penetrate and form flash, while insufficient depth traps gas and burns, the window is extremely narrow
Çözüm
①Control vent groove depth within 0.025mm; ②Add vent inserts at ends and rib positions; ③Regularly clean carbon deposits in vent grooves to keep them unblocked; after adjustment, take continuous samples to verify the effect, confirm stability before resuming mass production
Temel Çıkarım
PA66 vent groove depth has 0.025mm as the upper limit; walking a tightrope between gas trapping and flash, precision and cleanliness are both indispensable; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence
