What are the factors affecting the stability of the hot runner temperature control box's temperature measurement? The hot runner temperature control box is a controller used to maintain internal temperature balance within the hot runner system. It primarily utilizes a smart computer chip (MCU) within the sensor core to detect the temperature of the heating channels, processes the data internally, and then outputs an appropriate proportion of current to achieve temperature control. The stability of the temperature control depends on several important factors:

1) Temperature Measurement: Sample cycle parameters, data filtering processing, and temperature measurement circuit compensation all contribute to determining the temperature and its measurement accuracy.

2) PID Control: Adjusts the output current ratio, with relevant parameters including proportional band, integral time, and derivative time.

3) PIDD Control: Through phase angle control, relevant parameters include proportional band, integral time, and derivative time.

4) Auto-regulation: Analyzing the capacitance of the heating wire and the thermal constants of the mold, it provides the function of its dominant factors (having latent heat properties and heat dissipation capabilities, it aids in temperature control regardless of environmental changes).
