PBT injection speed management
문제 현상
Speed-related defects.
원인 분석
Excessive speed causes shear overheating; too slow causes front freezing.; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first when troubleshooting
해결 방법
①Multi-stage speed curve; ②initial stage to prevent jetting; ③middle stage filling; ④final stage to prevent overfilling.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
핵심 요약
The speed curve is optimized by stage.; after confirming effectiveness, solidify 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 in the future
