PU processing temperature fluctuation

문제 현상

During PU processing, temperature fluctuates ±5-8°C, exceeding ±2°C control precision

원인 분석

Improper PID parameters of temperature control system; heater bands aged, uneven power; thermocouple position improper, measurement deviation

해결 방법

1) Re-tune PID parameters; 2) Replace aged heater bands; 3) Adjust thermocouple position to the center of the melt pool

핵심 요약

Temperature fluctuation is caused by improper temperature control system; PID tuning and heater band replacement are key

PU temperature fluctuation PID tuning heater band thermocouple
