PA6 Regrind Problems

PA6 regrind = 'proportion + drying' dual control: nylon regrind absorbs moisture fast and degrades fast; repeated reuse has high risk, and key stressed parts resolutely use new material; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent rec...

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 Floating Fibers

GF-PA6 floating fibers = 'insufficient coating': raising temperature and slowing speed lets the resin wrap the fibers; appearance surfaces require process + texture + grade cooperation, and machine adjustment alone is hard to eradicate.

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 Trapped Air Burning

PA6 burning = 'poor venting': high-temperature nylon fears trapped air even more; opening and cleaning vent grooves is the focus of daily maintenance; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence.

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.

PA6 Nozzle Solidification Clogging

PA6 nozzle clogging = 'fast solidification + weak heating': the nozzle heating system is the lifeline; nylon crystallizes quickly and clogs as soon as it stops, and the heater band status and shutdown management must be in place.
