Detailed introduction:
 Minhang Mold Temperature Machine - Oil Circulation Temperature Control Machine/Water Type Mold Temperature Machine - Integrated Cold and Hot Mold Temperature Machine
The mold temperature machine includes an oil temperature machine and a water temperature machine,Oil circulation temperature control machine/water type mold temperature machineAlthough the heat transfer media used in the two are different, their basic operating principles are similar. After the heat transfer medium comes out of the application equipment, it enters the heating part of the system. The controller determines whether the unit needs to be heated or cooled based on the temperature signal feedback from the temperature sensor installed in the pipeline and the system set temperature. It controls the on/off of the heating tube and cooling water solenoid valve to heat or cool the heat transfer medium, and then the circulation pump continues to deliver the heat medium to the pipeline inlet of the application equipment, thereby achieving the purpose of constant temperature control. So there is not much difference in the operation process and principle between the two.The oil circulation temperature control machine is a mold temperature machine that uses thermal oil as a medium. Its control temperature can be divided into 200 ℃/300 ℃/350 ℃ oil temperature machines, with heating power ranging from 3KW to 1200KW. It is widely used in various industries, and the selection is mainly based on heating power, pump performance, and cooling capacity. Commonly used for heating molds, constant temperature control of rollers, constant temperature control of reaction vessels, or other similar industrial equipment temperature control needs. Its working principle is that high-temperature circulating heat transfer oil enters the mold temperature machine after coming out of the application equipment (mold). The equipment heats or cools the heat transfer oil according to the set temperature, and is transported to the pipeline inlet of the application equipment (mold) by the high-temperature oil pump, thereby achieving the purpose of constant temperature control. Mold temperature machine can be used for heating, constant temperature control of molds, or other industrial fields with similar requirements. Features can be selected according to customer requirements: air blowing and oil return function, instant cooling shutdown function/multi-point temperature control unit function/RS 485 communication function/realizing automation management  
A water type mold temperature machine is a mold temperature machine that uses water as a medium. Under normal atmospheric pressure, the boiling point of water is 100 ℃. Therefore, without pressurization, the control temperature of the water temperature machine can only be less than or equal to 100 ℃. In practical applications, by increasing the pipeline pressure, the temperature control of the water temperature machine can be raised to 180 ℃, thereby expanding the application range of the water temperature machine. The heat transfer medium of the water temperature machine is water. Compared with the heat transfer oil, water has the characteristics of high specific heat and fast heat transfer speed. Therefore, under the same application conditions, the heat transfer effect of the unit will be better. In addition, the water temperature machine also has the advantages of easy material selection, no pollution, low price, and simple operation and maintenance. Its disadvantage is that the temperature control range is relatively narrow, with a control temperature of 180 degrees, while the oil temperature machine can reach 350 degrees. Another point is that due to the use of pressurized heating, the unit has certain pressure resistance requirements for the pipeline system. 
The integrated cold and hot mold temperature machine includes temperature control for heating and cooling, temperature control, and is widely used in various industries Cold and hot cycle machines can achieve mutual switching, accelerate production progress, and reduce energy consumption. The heating function of the mold temperature machine and the cooling function of the chiller can be integrated and switched by the microcomputer control system according to the production process.  
          
           
           
           
           Mold Temperature Machine - Oil Circulation Temperature Control Machine/Water Type Mold Temperature Machine - Integrated Cold and Hot Mold Temperature MachineFunction introduction:           1. Heat transfer pump: Taiwan Yuan's new series high-temperature pump is used, which runs quickly and accurately, has obvious heat transfer effect, low noise, and no leakage           2. Temperature controller: Adopting Omron series temperature controller with built-in temperature control module, P.I.D value can be independently set according to process requirements, with a wide temperature control range and a temperature control of ± 1 ℃           3. Electrical components: All electrical components use Schneider series electrical components, with low failure rate and extended equipment service life Thermal oil heater control system: microcomputer control, 5-way single-chip circuit board, dual group PID, heating and cooling autonomous operation           4. Heating element: The heating wire is introduced from Sweden and is in a circular shape. It is installed in a stainless steel tube, and the gap is filled with magnesium oxide powder with thermal conductivity and insulation properties. It is inserted into the tube and connected by a flange. It is placed in the central part of the stainless steel heating drum, providing uniform heating and avoiding local overheating           5. Safety protection device: When the temperature is abnormal, the circulating oil temperature exceeds the upper limit and an alarm is triggered, cutting off the main power supply. The contactor is stuck and an abnormal heating alarm is triggered and indicated. The heating action is automatically stopped when the system pressure is abnormal. The BY-PASS pressure relief circuit protects the pump, and the liquid level switch detects the oil level to prevent oil shortage and gives an alarm indication. The safety protection is complete and the fault display is displayed
