TPE Product Recycling
Problem Phenomenon
Performance decreases when using recycled material.
Cause Analysis
Recycled material heat history and contamination; ratio out of control.; 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
Solution
①Control the ratio; ②classified management; ③test performance; ④use new material for critical parts.; 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
Key Takeaway
Recycled material is limited in quantity and use.; 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
