PSU Post-Processing Process Adaptation
Problem Phenomenon
【Problem Phenomenon】PSU parts require post-processing such as ultrasonic welding, bonding, and laser marking, and process adaptation is unclear
Cause Analysis
Sulfone polymers can handle almost all post-'2079851475616104453es: ultrasonic welding, bonding, laser marking, heat staking, tapping, and machining; the process window is wide; when troubleshooting on site, verify item by item according to this mechanism, avoiding blind machine adjustment based only on experience
Solution
Choose ultrasonic welding or bonding according to connection needs and perform strength verification; adjust laser marking parameters according to the material; use sharp tools for machining to prevent stress; after adjustment, continuously sample to verify the effect, confirm stability before resuming mass production
Key Takeaway
PSU post-processing is a full package, from ultrasonic welding to laser marking; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
