ASA cooling time setting
Problem Phenomenon
[Problem phenomenon] ASA demolding deformation or cycle too long, cooling time improper
Cause Analysis
Insufficient cooling causes ejection deformation, excessive cooling wastes cycle; ASA amorphous material cooling aims at shape setting, proportional to wall thickness squared; during on-site investigation, verify item by item according to this mechanism, avoid blindly adjusting the machine based on experience alone
Solution
Cooling calculated by wall thickness and demolding rigidity verified; uniform mold temperature shortens required cooling; cycle optimization does not sacrifice demolding quality; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
ASA cooling calculated by wall thickness, demolding rigidity is the release standard; after confirming effectiveness, solidify 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
