PSU Shrinkage and Accuracy
문제 현상
Dimensional accuracy of PSU precision parts is difficult to control; shrinkage is small but process-sensitive; batch fluctuations exceed tolerance.
원인 분석
PSU is amorphous with small shrinkage but high process sensitivity; temperature and pressure fluctuations directly affect it; dimensions change after internal stress release; measurement conditions are inconsistent.; During on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based solely on experience
해결 방법
①Stable control of process parameters; ②Low-stress molding; ③Standardize measurement conditions; ④SPC process control.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
핵심 요약
PSU precision parts rely on process stability; internal stress management runs throughout; standardized measurement is the basis of credible data.; After confirming effectiveness, solidify the parameters and practices into the work instructions to prevent recurrence
