Mold Temperature Management of PLA Products
Problem Phenomenon
Confusion in mold temperature setting.
Cause Analysis
Low mold temperature gives an amorphous transparent but brittle product; high mold temperature gives crystallization and heat resistance but a long cycle.; 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
①Select the mold temperature strategy according to product requirements; ②Low mold temperature for transparent parts; ③High mold temperature heat setting for heat-resistant parts; ④Record and verify.; After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PLA mold temperature is a performance path choice; transparency and heat resistance cannot be achieved at the same time.; 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
