Hot runner temperature control box is hot runner temperature controller, hot runner temperature control box is composed of a continuous keep hot runner system required the temperature value of the equipment, comprising a temperature control card, air switch, a box body, a fan, a wire holder and cable etc.. The temperature control box is arranged on the temperature control card, and the temperature of the hot runner system is detected, and the temperature of the target point is kept stable by adjusting the output power. Temperature control box is controlled by the microprocessor, temperature control precision is up to 0.5 DEG C; double LED digital show that has a variety of fault display and alarm, to discover and solve problems; output interface using the international standard industrial socket, widely used in countries of the * * * fluid system; thermocouple type K J type can be interchangeable.

Heat flow temperature control box as the name suggests, is used to control the internal temperature balance of hot runner system controller, as one of "the four King Kong" hot runner system is essential, and hot runner system depend on each other but relatively independent. Its accuracy, stability, all have a serious impact on the hot runner system, and the quality of hot runner system is also similarly affects the box temperature control accuracy, stability and service life; usually it consists of temperature control card, chassis, heavy duty connectors and power line terminal row, and so on.

Uses: with the wide application of mold runner in the electronics, automotive, medical, daily necessities, toys, packaging, building, office equipment etc. various industrial sectors, hot runner temperature control box has become one of the plastic mold industry essential industrial equipment. Currently on the market, the types of hot runner temperature control box is: touch temperature control box, international standard plug card temperature control box, a card double point temperature control box, meter type temperature control box, the brand is numberless as the sand.

Principle: the temperature control box is a continued to maintain the desired temperature value of the equipment, it is mainly through the table within the core of intelligent computer chip (MCU) hot runner temperature detection, after intelligent internal computer data processing, appropriate proportion of the current value of the output, so as to achieve temperature control purposes, the temperature control accuracy stability depends on the following several important factors:

1> temperature measurement: the sampling period parameter, the data filter processing determines the temperature, the measuring circuit temperature compensation and so on determine the precision of the temperature measurement;

2>PID control: through the adjustment of the proportion of the output current, the relevant parameters are proportional, integral time and differential time;

3> PIDD control: the phase control, the relevant parameters are proportional, integral, differential time;

4> automatic regulation: through the analysis of the heating wire of the capacitor and mold thermal constant, to provide the function of its leading factor (with latent heat and heat sink

How the environment changes it all helps to precisely control the temperature.
