Tips: Working principle of hot runner temperature controller
The hot runner temperature controller is a device that continuously maintains the required temperature value. It mainly detects the temperature of the hot runner through the Microprogrammed Control Unit (MCU) in the controller, then processes the internal data to output the appropriate proportion of power value, to achieve the purpose of hot runner temperature control. The accuracy and stability of hot runner temperature controller mainly depend on the following important factors:

1. Temperature measurement: Sampling cycle parameters and data filter processing decide temperature, and measurement circuit temperature compensation decide temperature measurement accuracy.
2. PID control: Reflect the proportion of output power through regulation, the related parameters have proportional section, integral time and differential time.
3. PIDD control: Through phase angle control, the related parameters have proportional section, integration time and differential time.
4. Automatic adjustment: By analyzing the capacitance of the heating wire and the thermal constant of the mould, it has the function of providing the leading factor (No matter how the environment changes, it helps to accurately controls the temperature).
5. Output mode: Can be changed according to the environment
   SSR (PIDD) mode: Accurate temperature control can be achieved, but the noise of the power supply is much larger than the PWM mode.
   PWM (PID) mode: The current noise is small, but the ability to control specific temperature is worse than SSR mode.
