PESU Recycled Material Utilization
Problem Phenomenon
PESU appearance-defect parts are crushed, dried and re-molded, with no performance loss.
Cause Analysis
PESU wet resin processed appearance-defect parts; re-molding after crushing and drying; no performance loss; recycling value; quality management.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Defective part recycling management; ②drying specifications; ③re-molding verification; ④performance testing; ⑤ratio control.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PESU recycling utilization is a material advantage; standardized management ensures quality; verification ensures performance.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
