Die casting
Dual control technology for casting and forging, combined with multiple models of die-casting machines, meets the needs of various complex structural parts.
Advantages of magnesium alloy processing
Castability
The liquid has better fluidity than aluminum, a lower melting point, and lower energy consumption, making it suitable for producing thin-walled parts.
accuracy
The product dimensions are stable and are minimally affected by changes in external temperature and time.
Processability
Magnesium alloy die casting has high efficiency (production speed can reach 1.5 times that of aluminum alloy) and lower mold wear.
Machinability
The cutting resistance is 56% of that of aluminum alloy.
Dual control technology for casting and forging
The dual-control casting and forging technology combines the advantages of die casting and forging, and has the function of fluctuating high pressure casting and forging. It can perform controlled fluctuating high pressure forging on the castings after high pressure casting, which can effectively improve defects such as porosity, shrinkage cavities and gas pores in the castings, while improving the mechanical properties of the products.

Gas-protected integrated furnace
Automatically supplying molten magnesium metal that meets technical requirements to the die-casting machine.
In magnesium alloy die casting, the integrated gas-protected furnace is a core technological equipment for ensuring high-quality casting production. Unlike traditional melting methods, this furnace adopts a fully enclosed structure, injecting argon or a mixed protective gas to create a stable inert atmosphere, effectively isolating oxygen and preventing oxidation or even combustion of molten magnesium at high temperatures. Its automated system is linked in real time with the die casting machine, precisely controlling the melting temperature, holding time, and magnesium composition to ensure a continuous supply of high-quality molten magnesium with uniform composition, stable temperature, and low gas content to the die casting unit. This integrated design not only significantly improves the stability and safety of the liquid supply process but also significantly reduces casting defects caused by oxidation inclusions. It also reduces manual intervention and protective gas consumption, making it a key component in achieving high-efficiency, low-loss, and fully automated die casting production of magnesium alloys.
