Nucleating Agent Application for PLA Products
Problem Phenomenon
Slow crystallization and poor heat resistance.
Cause Analysis
Nucleating agents promote heterogeneous nucleation and increase the crystallization rate; multiple nucleating agents have been verified in the literature.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Add nucleating agent; ②Optimize the addition amount; ③Combine with heat setting; ④Verify crystallinity improvement.; After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Nucleating agents are the standard means of PLA crystallization modification.; 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
