해결 방법
①Increase injection pressure and speed; ②appropriately increase temperature; ③enlarge runner and gate; ④improve venting.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
핵심 요약
Troubleshoot short shot from pressure, temperature and runner.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; Include this case in the defect archive as a troubleshooting reference for subsequent similar problems
