Application Scenarios of Die-casting Mold Temperature Controller

In addition, the die casting-specific oil temperature machine is also equipped with a complete safety protection system. For magnesium alloy die casting scenarios with flammable characteristics, it is also equipped with explosion-proof electric heaters, pressure interlock protection systems and nitrogen purging devices to ensure production safety. These protection mechanisms can effectively avoid equipment damage and safety accidents caused by abnormal working conditions such as over-temperature, lack of oil and pipeline leakage, and improve the reliability of the equipment during long-term continuous die casting operations.
Key Application of Oil Temperature Machine in Die Casting Industry
The oil temperature machine is widely used in various die casting scenarios, covering aluminum alloy, magnesium alloy, zinc alloy and other die casting processes. Different types of die casting-specific oil temperature machines are suitable for different die casting materials and product requirements. Its core application value is reflected in improving casting quality, optimizing production efficiency and reducing production costs. The specific application scenarios are as follows:
1. Aluminum Alloy Die Casting (Main Application Scenario)
Aluminum alloy die casting is the most common application field of oil temperature machines, which is widely used in the production of auto parts (such as engine brackets, gearboxes, integrated die casting body of new energy vehicles), hardware accessories and other products. The aluminum alloy die casting process requires the mold temperature to be controlled between 200℃-300℃. The oil temperature machine can stably maintain the mold temperature in this range, improve the fluidity of the aluminum alloy melt, ensure the full filling of the mold cavity, and reduce common defects such as air holes, shrinkage holes and cold shut in castings. For example, a Dongguan aluminum alloy wheel hub factory reduced the casting air hole rate from 8% to 0.5% after selecting an oil temperature machine with an upper limit of 300℃. In the integrated die casting of new energy vehicles, the high-temperature oil temperature machine with a working temperature of up to 350℃ can meet the high-temperature requirements of the die casting process and improve the forming efficiency and quality of large structural partssuperscript:4>.
2. Magnesium Alloy Die Casting
Magnesium alloy has the characteristics of light weight and high strength, and is widely used in aerospace, 3C electronic products and other fields. The magnesium alloy die casting process requires higher mold temperature, usually between 300℃-400℃, and has strict requirements on safety. The die casting-specific oil temperature machine can not only meet the high-temperature control requirements of magnesium alloy die casting, but also be equipped with explosion-proof devices to avoid safety hazards caused by the flammability of magnesium alloy. It can ensure the stability of the mold temperature, improve the forming quality of magnesium alloy castings, and reduce the phenomenon of oxidation and burning of the melt during the die casting processsuperscript:4>.
3. Zinc Alloy Die Casting
Zinc alloy die casting has the advantages of low melting point and fast forming, and is suitable for the production of small and precise parts such as hardware accessories and electronic components. The mold temperature requirement for zinc alloy die casting is relatively low, usually between 160℃-200℃. The oil temperature machine can realize precise temperature control in this range, ensure the surface smoothness of zinc alloy castings, avoid defects such as shrinkage and deformation, and at the same time shorten the cooling time of the mold and improve production efficiency. For some zinc alloy die casting scenarios that need auxiliary cooling, the oil temperature machine can also be combined with a water cooling system to achieve precise temperature regulation of local parts of the moldsuperscript:4>.
4. Special Die Casting Scenarios
With the development of the die casting industry, the application of oil temperature machines is also expanding to special die casting scenarios. In the precision die casting of auto parts (such as engine cylinder heads, gearbox shells), the oil temperature machine with multi-zone independent temperature control function can realize precise temperature control of different parts of the mold, ensuring the dimensional accuracy and surface quality of castings. In the large-scale integrated die casting of new energy vehicles, the distributed temperature control scheme of "host + remote heat exchange station" is adopted to meet the uniform temperature rise demand of super large molds (5-8 meters in size) and ensure the forming quality of large structural parts. In addition, in the die casting of high-precision aerospace parts, the oil temperature machine with high temperature control precision and stable performance provides reliable temperature guarantee for the die casting process.
