PLA product poor surface gloss
Problem Phenomenon
The surface is hazy and not glossy.
Cause Analysis
Low mold temperature causes poor replication or uneven crystallization; PLA should have good gloss.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solution
① Appropriately increase mold temperature; ② polish the cavity; ③ improve crystallization uniformity; ④ control degradation.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PLA's gloss advantage must be realized through the process.; 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
