PPSU heat staking
Problem Phenomenon
PPSU heat staking strength and reliability; assembly process.
Cause Analysis
PPSU can be heat staked; staking temperature and pressure; structural design; strength consistency; long-term performance.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Staking parameter optimization; ②structural design; ③strength testing; ④long-term verification.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Key Takeaway
PPSU heat staking is an assembly option; parameters and structure are equally important; testing ensures reliability.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
