EVA Shoe Sole Insufficient Wear Resistance
Problem Phenomenon
The wear resistance test of foamed shoe soles does not meet the standard.
Cause Analysis
An excessive foaming ratio makes the material density low and the wear resistance decreases; insufficient wear-resistant components in the formula is also a cause.; During on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
Solution
①Control the foaming ratio to ensure density; ②optimize the formula to improve wear resistance; ③test the wear resistance indicators; ④use solid soles in key parts.; After adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
Wear resistance and lightweighting need to be balanced; the foaming ratio is the master switch of density and performance.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
