ABS recycling utilization
Problem Phenomenon
[Problem phenomenon] Feasibility and precautions of ABS recycling utilization
Cause Analysis
ABS is recyclable: crushed and re-dried, blended at ≤20%; multiple heat histories reduce impact and color; closed-loop recycling is mature in home appliance dismantling; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
Solution
Recycled material ≤20% and verified; sorted recycling ensures purity; high-requirement parts limit recycled material; 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
ABS recycling is mature, 20% ratio and purity are the keys; 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
