Weight Control of PS Products
Problem Phenomenon
Product weight fluctuations affect assembly.
Cause Analysis
Unstable metering or worn check ring; PS density is stable, so weight directly reflects the filling condition.; During on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based solely on experience
Solution
①Check metering accuracy; ②Disassemble and inspect the check ring; ③Stabilize temperature; ④SPC monitoring.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Weight is a window into filling consistency; SPC management is effective.; After confirming effectiveness, solidify the parameters and practices into the work instructions to prevent recurrence; Include this case in the defect archive as a reference for troubleshooting similar problems in the future
