SMMA Thick-Wall Part Processing
Problem Phenomenon
SMMA high flowability suits thick-wall large volume, but process management.
Cause Analysis
SMMA high flowability is especially suitable for thick parts and large-volume parts; but thick-wall cooling and stress; gate design; cycle management; quality control.; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
Solution
①Utilize the high flow advantage; ②thick-wall cooling management; ③gate design; ④cycle optimization; ⑤quality monitoring.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
SMMA thick-wall processing is a material advantage; cooling and stress are challenges; management keeps quality and efficiency.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
