PC/ABS cooling system design
Problem Phenomenon
Uneven cooling deformation.
Cause Analysis
Unreasonable water channel layout; large temperature difference.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solution
①Optimize water channel layout; ②conformal cooling; ③balance flow; ④detect temperature difference.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record the parameter changes, to facilitate locating the effective measures
Key Takeaway
Cooling design is the core of deformation prevention.; 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
