TPE Product Sink
Fenómeno do problema
Depression sink at thick walls.
Análise das causas
Insufficient shrinkage compensation or uneven wall thickness; insufficient holding pressure and time.; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solução
①Increase holding pressure; ②core out thick areas; ③optimize the gate; ④uniform wall thickness.; 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
Conclusão principal
Sink follows the shrinkage compensation mechanism; structural uniformity is fundamental.; after confirming effectiveness, fix 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
