Actual Measurement Calibration of PEEK Melt Temperature
문제 현상
[Problem Phenomenon] The barrel set temperatures are the same, but the state of PEEK products differs greatly between machines
원인 분석
There is a deviation between the set temperature and the actual melt temperature, and heater band aging and thermocouple position differences amplify the deviation; Fast Heat requires using a pyrometer to actually measure the melt temperature at 370-390℃ by air-shot through the nozzle
해결 방법
Regularly actually measure the melt temperature by air-shot to calibrate each machine's deviation; establish machine melt temperature archives; when switching to another machine for production, re-calibrate the process according to the actually measured melt temperature; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
핵심 요약
PEEK process transfer is based on the actually measured melt temperature, and set values are for reference only; 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
