Transparency of PLA Products
Problem Phenomenon
High haze of transparent products.
Cause Analysis
Crystallization makes transparent PLA hazy; degradation also affects transparency.; 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
①Control crystallinity to maintain the amorphous state; ②Control temperature to prevent degradation; ③Select high-transparency grades; ④Optimize cooling.; After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PLA transparency relies on maintaining the amorphous state.; 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
