PA12 Surface Glosslessness
Sorun Belirtisi
【Problem phenomenon】PA12 product surfaces were dull and glossless, with low appearance grade
Neden Analizi
Insufficient product density, slow filling speed, low mold temperature, and poor venting prevent the melt from fully replicating the cavity surface; microscopic material shortage on the surface means loss of gloss; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Çözüm
Increase the melt amount and raise injection pressure; raise barrel temperature and injection speed; raise mold temperature; fully vent to improve replication; after adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
Loss of gloss is insufficient cavity replication, with density, speed, temperature, and venting as a four-in-one; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
