PCABS cooling time optimization
Problem Phenomenon
【Problem Phenomenon】PC/ABS cooling time improper, demolding deformation or cycle too long
Cause Analysis
Insufficient cooling causes ejection deformation, excessive cooling wastes cycle; amorphous material cooling targets shape setting; uniform mold temperature can shorten cooling; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone
Solution
Cooling calculated by wall thickness to verify demolding rigidity; mold temperature uniformization shortens the cycle; do not sacrifice quality to compress the cycle; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PC/ABS cooling is calculated by wall thickness, 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 similar problems later
