PCABS Recycling and Sustainability
Problem Phenomenon
[Problem Phenomenon] Feasibility and limitations of PC/ABS recycling and utilization
Cause Analysis
PC/ABS is recyclable, but thermal history affects PC phase performance; closed-loop recycling and chemical recycling are under development; the regrind ratio affects performance; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
Regrind ≤15% with performance verification; evaluate closed-loop recycling systems; limit regrind for high-requirement parts; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
PC/ABS recycling is feasible, but the ratio and performance must be balanced; 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 similar problems in the future
