Some friends will fall into a dilemma when purchasing a mold temperature controller, because they are unfamiliar or even completely ignorant of the temperature control equipment parameters, and it is easy to make a wrong choice. So in the plan of purchasing a mold temperature controller, what parameters need special attention? Generally speaking, to simply understand the basic information of the mold temperature controller, the following parameters need to be understood.
1. The temperature control range and temperature control accuracy of the mould temperature machine.
Usually, the description of the temperature control range of the mold temperature machine is from room temperature to the highest temperature. For example, for equipment with room temperature ~ 300 ° C, the highest temperature that can be achieved is 300 ° C; and the temperature control accuracy refers to the operating temperature and the set temperature of the equipment in a stable state. The deviation value is generally ±1, ±0.5 or ±0.1. The higher the temperature control accuracy, the higher the requirements for the temperature control accessories used.
2. How to choose the power of the mould temperature controller.
The power of the mold temperature controller generally refers to the total power of the equipment, including the power of the heater, the power of the pump, and the power of the electrical components. The total power of the mold temperature machine is calculated according to the needs of the customer’s equipment, in order to fully meet the use requirements. Considering the heat conversion rate and loss of the mold temperature machine, the total power of the mold temperature machine will be higher than that according to the The calculated power needs to be large.
3. The heat transfer medium and cooling method used by the mold temperature controller.
The mould temperature controller is driven by the pump to drive the heat transfer medium (usually water or oil) from the pipeline equipped with a built-in heater and cooler to the mold, and then returns to the heating pipeline from the mold. The controller measures the temperature feedback through the temperature sensor, adjusts the heating and cooling actions, and controls the temperature of the thermal fluid to adjust the temperature of the mold.
4. The flow rate and pressure of the mold temperature controller.
Accurate heating and temperature regulation can only be achieved if the mold temperature controller ensures sufficient heat medium flow and pressure. Generally speaking, within a certain range, the greater the flow rate and the higher the pressure of the mold temperature controller, the smaller the deviation of its temperature control and the better the temperature control effect.
5. The interface, frame, special customization and other parameters of the mold temperature machine.
