PSU '2079851475616104458 Cracking
Problem Phenomenon
PSU sheets crack and show uneven thickness during '2079851475616104458; the forming temperature window is narrow; scrap rate is high for complex shapes.
Cause Analysis
PSU '2079851475616104458 temperature is improperly controlled; internal stress of the sheet is released and deforms during heating; excessive draw ratio causes local thinning and rupture; uneven heating.; During on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based solely on experience
Solution
①Control '2079851475616104458 temperature per material specifications; ②Select low-stress sheets; ③Design reasonable draw ratios; ④Ensure heating uniformity.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PSU '2079851475616104458 is the art of balancing temperature and stress; sheet quality is the foundation; design draw ratio determines success or failure.; After confirming effectiveness, solidify the parameters and practices into the work instructions to prevent recurrence
