PA66 uneven gloss
Sorun Belirtisi
PA66 appearance part surface has uneven brightness and darkness
Neden Analizi
Uneven cavity temperature makes melt replication states different; inconsistent mold surface polishing levels or haze in poorly vented areas; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience
Çözüm
Homogenize cavity temperature; unify mold surface polishing; improve venting; appropriately raise holding pressure; after adjustment, take continuous samples to verify the effect, confirm stability before resuming mass production; change only one variable at a time and record parameter changes to facilitate locating effective measures
Temel Çıkarım
Gloss uniformity relies on the coordination of mold temperature, mold surface, and venting; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
