PA6 Product Post-crystallization Dimensional Drift

PA6 post-crystallization = 'the crystallinity given by mold temperature is insufficient': raising mold temperature to lock crystallization is fundamental; dimensions must be managed 'after aging', and parts molded at low mold temperature must especially guard against post-crystallization.

PA6 Glass Fiber Mold Wear

GF nylon = 'abrasive': mold steel must be upgraded; wear-resistant hardware + life management is the material basis for quality assurance, and wear monitoring must be normalized; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence.

PA6 Glass Fiber Reinforced Warpage

GF-PA6 warpage = 'fiber orientation': the gate is the switch; orientation-type warpage has a fixed direction, hard pressing by cooling is ineffective, and adjustment must be made from the source of gate and orientation.

PA6 Sink Marks

PA6 sink marks = 'compensation management': holding pressure and freeze-off are the technique, rib thickness and thick walls are the root; crystalline materials shrink greatly, and compensation and structure must be emphasized equally; after confirming effectiveness, solidify the parameters and p...

PA6 Weak Weld Lines

PA6 weld lines = 'entangle before crystallization': raising temperature, increasing speed, and venting in three ways; for fast-crystallizing nylon, confluence temperature is decisive, and position planning must also be advanced.
