The function of the mold temperature machine is to heat or cool the mold and maintain its working temperature to ensure the quality of the injection molded parts and optimize the processing time. There are two types of mold temperature machine: water temperature machine and oil temperature machine. In the injection molding industry, the temperature of the mold has a decisive effect on the quality of the injection molded parts and the injection time.
The main points of the application of the mold temperature machine in the injection mold: the thermal balance of the injection mold; the purpose of controlling the mold temperature and the influence of the mold temperature on the injection molded parts; the preparation conditions for effectively controlling the mold temperature; the mold temperature machine; the heat transfer fluid; the advantages of the mold temperature machine And economy.
What problems should be paid attention to when buying mold temperature machine
1. When buying a mold temperature machine, we must first know which models of the mold temperature machine are available
For example, how many degrees of temperature are used, whether the water-type mold temperature machine is used or the oil-type mold temperature machine, etc. There is also the size of the heating power.
2. The mold temperature machine is divided into two types: water type mold temperature machine and oil type mold temperature machine, the temperature control range is generally ordinary who is the mold temperature machine can reach 120 degrees, and the temperature of the ordinary oil type mold temperature machine can be controlled within 200 degrees The temperature of the high-temperature water-type mold temperature machine can be controlled within 180 degrees, and the temperature of the high-temperature oil-type mold temperature machine can be controlled within 350 degrees. The 304 stainless steel integrated molding pipeline has a temperature control accuracy of ± 1 ℃, no professionals, and easy operation .
What problems should be paid attention to when buying mold temperature machine
1. The heating pipes and pipelines must be made of stainless steel. The iron can be scrapped after one year.
2. The motor requires a brand.
3. Solenoid valves should be used well, and imported brands from Taiwan and Italy are relatively stable.
4. Temperature control must use PID, the temperature can be controlled accurately.
