Fenómeno do problema
During PU processing, temperature fluctuates ±5-8°C, exceeding ±2°C control precision
Análise das causas
Improper PID parameters of temperature control system; heater bands aged, uneven power; thermocouple position improper, measurement deviation
Solução
1) Re-tune PID parameters; 2) Replace aged heater bands; 3) Adjust thermocouple position to the center of the melt pool
Conclusão principal
Temperature fluctuation is caused by improper temperature control system; PID tuning and heater band replacement are key
