Configuration And Use Of High Temperature Mold Temperature Machine

The high temperature mold temperature machine has a high operating temperature, and the maximum temperature can reach 350 °C. Therefore, in the selection process of the high temperature mold temperature machine, it is necessary to understand the configuration of the mold temperature machine in detail to avoid product defects caused by the configuration of the mold temperature machine. , In the process of using the mold temperature machine, you need to pay attention to the standardized operation mode to avoid safety accidents. The configuration of the mold temperature machine should be comprehensively judged according to the processed materials, the weight of the mold, the required preheating time and the productivity kg/h . When using heat transfer oil, the operator must observe such safety regulations: do not place the mold temperature machine near the heat source furnace; use tapered leak-proof and temperature and pressure resistant hoses or hard pipes for joints; regularly Check the temperature control loop mold temperature machine, whether there is leakage of joints and molds, and whether the function is normal; replace the heat transfer oil regularly; artificial synthetic oil should be used, with good thermal stability and low coking tendency. In the use of the mold temperature machine, choose the appropriate Heat transfer fluid is extremely critical. Using water as heat transfer fluid is economical, clean, and easy to use. Once the temperature control loop such as a hose coupling leaks, the water flowing out can be directly discharged to the sewer, but water as a heat transfer fluid also has disadvantages: the boiling point of water is low. ; Depending on the composition of the water, corrosion and scaling may occur, causing an increase in pressure loss and a decrease in the efficiency of heat exchange between the mold and the fluid, etc. When using water as a heat transfer fluid, the following precautions should be considered: Pre-treatment with anti-corrosion agents Temperature control loop; use filter before water inlet; regularly clean water temperature machine and mold with rust removal agent. There is no disadvantage of water when using heat transfer oil. The boiling point of oil is high, they can be used in cases where the temperature is higher than 300 ℃ or even higher , but the heat transfer coefficient of heat transfer oil is only 1/3 of that of water, so the oil temperature machine is not as widely used as the water temperature machine in injection molding.

When purchasing a high temperature mold temperature machine, you should not only pay attention to the price, but the cost performance is the most important. The cheap mold temperature machine seems to save costs, but the unreliable stability of the mold temperature machine will lead to more serious problems in the later use process. Large investment, and even security incidents.
