COC Recycling Utilization
Problem Phenomenon
COC recycled material performance, heat history and contamination.
Cause Analysis
COC recycling; heat history; performance retention; contamination prevention and control; recycling ratio; application restrictions.; During on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
Solution
①Recycling ratio; ②performance inspection; ③contamination prevention and control; ④application matching; ⑤quality traceability.; After adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
Heat history and contamination management of COC recycling; inspection and traceability ensure quality; matching reduces risk.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
