ABS dimensional deviation
Sorun Belirtisi
[Problem Phenomenon] ABS product dimensional drift, unstable between batches
Neden Analizi
Mold temperature and holding pressure fluctuation, moisture content change, regrind fluctuation affect shrinkage; 0.4-0.7% shrinkage requires locking the process; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based only on experience
Çözüm
Lock mold temperature, holding pressure, and drying; SPC monitoring; fix regrind; after adjustment, continuously sample to verify the effect, resume mass production only after confirming stability; change only one variable each time and record parameter changes to facilitate locating effective measures
Temel Çıkarım
ABS dimensions rely on parameter locking and SPC monitoring; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems later
