Q

SMMA Drying Management Misconceptions

A

SMMA drying management must grasp the boundary between 'not needed' and 'needed'; sampling inspection is the judgment basis; sealed storage is prevention.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

SMMA Material Recognition and Confusion with PMMA

A

The process difference between SMMA and PMMA is the material essence; correct recognition is the premise of quality and efficiency; supplier data is the authoritative basis.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

PVDF Appearance Part Flow Mark and Gloss Unevenness

A

For appearance parts, stabilize drying and temperature first; gloss differences are mostly stability problems; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference f...
