ABS cooling time setting
Problem Phenomenon
[Problem phenomenon] Improper ABS cooling, demolding deformation or excessively long cycle
Cause Analysis
Cooling time is about 5 seconds per 1mm wall thickness; insufficient causes ejection deformation, too long wastes cycle; uniform mold temperature can shorten the required cooling; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
Solution
Cooling estimated by wall thickness×5s and verified; mold temperature uniformity; do not sacrifice quality to shorten the cycle; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
ABS cooling 5 seconds per millimeter, demolding rigidity has the final say; 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
