HDPE Flash
문제 현상
HDPE injection molded part has flash at parting line
원인 분석
Insufficient clamping force or parting line wear lets HDPE overflow when flowability is good; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based solely on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
해결 방법
Calculate clamping force; fit the parting line; stage injection pressure; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
핵심 요약
For HDPE flash, check clamping force and parting line; 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
