해결 방법
①Increase the mold temperature; ②increase the injection speed; ③improve cavity polishing; ④appropriately increase the melt temperature.; after adjustment, continuously sample and verify the effect, and resume mass production after confirming stability
핵심 요약
Orange peel is a manifestation of poor replication; increasing temperature and speed to improve replication ability can improve it.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
