PC/ABS shrinkage rate management
Fenómeno do problema
Dimensional deviation of precision parts.
Análise das causas
PC/ABS shrinkage rate 0.5~0.7% is low and predictable; but process fluctuations still cause deviation.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone
Solução
①Design mold compensation according to 0.5~0.7%; ②stabilize '2079851475616104453; ③measure actual shrinkage rate for verification; ④SPC monitoring of key dimensions.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusão principal
Low and predictable shrinkage rate is the precision advantage of PC/ABS; only a stable process can deliver it.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
