AEPDS weld line
Problem Phenomenon
AEPDS weld line strength and appearance, rubber phase distribution influence.
Cause Analysis
AEPDS weld line position rubber phase distribution; convergence temperature; interfacial bonding; strength retention; visible appearance.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
①Temperature and speed optimization; ②gate position; ③venting; ④strength test; ⑤appearance management.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
AEPDS weld line management considers both strength and appearance; process optimization is the main means; testing ensures quality.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
