TPE Product Poor Surface Gloss
Problem Phenomenon
Product surface is foggy with insufficient gloss.
Cause Analysis
Low polishing grade of cavity surface; low melt temperature and mold temperature, slow injection speed and insufficient '2079851475616104451 all affect gloss.; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
Solution
①Improve the cavity surface polishing grade; ②appropriately raise melt temperature and mold temperature; ③adopt higher injection speed; ④ensure the material is fully dried.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Improving the polishing grade is the most direct method to improve gloss; process temperature, speed and drying cooperate for improvement.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
