Glass Fibre processing temperature fluctuation
Problem Phenomenon
Glass Fibre during processing temperature fluctuates ±5-8°C, exceeding ±2°C control accuracy
Cause Analysis
Temperature control system PID parameters improper; heater bands aged, power uneven; thermocouple position improper, measurement deviation
Solution
1) Re-tune PID parameters; 2) replace aged heater bands; 3) adjust thermocouple position to melt pool center
Key Takeaway
Temperature fluctuation is caused by improper temperature control system; PID tuning and heater band replacement are key
