AEPDS surface quality
Problem Phenomenon
AEPDS product surface gloss and flow marks, rubber phase and process influence.
Cause Analysis
AEPDS surface quality is affected by rubber phase; gloss; flow marks; injection speed; mold temperature; mold polishing.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
①Injection speed optimization; ②mold temperature management; ③mold polishing; ④surface inspection; ⑤process fixation.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
AEPDS surface quality needs fine process management; rubber phase is the material factor; inspection ensures consistency.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
