Cooling Management of PLA Products
Problem Phenomenon
Insufficient cooling causes deformation.
Cause Analysis
PLA crystallizes slowly and needs sufficient setting; uneven cooling causes warpage.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience; this mechanism has been repeatedly verified by industry literature and should be confirmed first during troubleshooting
Solution
①Ensure cooling time; ②Balance water channels; ③Uniform mold temperature; ④Detect temperature differences.; 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 parameter changes, making it easier to identify effective measures
Key Takeaway
Cooling management is the key to PLA setting.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
