Application:

Mold temperature machine, also called the mould temperature control machine, widely used in plastic injection, die casting of light guide plate, rubber tires, wheel, chemical reaction kettle, mixer and so on all walks of life. HEWH series water heaters have both standard and high temperature models, which are used to heat up the mould and maintain temperature, also they can be used in other similar applications. High temperature water from the mould is returned to the cooling tank and cooled by direct cooling. It is then pressurized by the high-pressure pump, sent to the heating tank and finally to the mould with a constant temperature.

Working principle:

Mold temperature machine by the water tank, heating and cooling system, power transmission system, liquid level control system and temperature sensors, spree and other parts. Normally, the pump to make hot fluid in the power transmission system from water tank has a built-in heater and cooler to mold, then back to the tank from the mold; The temperature sensor measuring the temperature of the thermal fluid and sends the data to the control part of the controller; Controller to regulate the temperature of the thermal fluid flow, and indirectly, to regulate the temperature of the mold. If in production mold temperature machine, mold temperature more than set value of the controller, the controller will open the solenoid valve connected to feed line, until the temperature of the heat transfer fluid, namely the temperature of the mold back to the set value. If the mold temperature is lower than the set value, it will open the heater controller.
