Comparatively speaking, the working conditions of an aluminum alloy die casting die are different from those of other dies. It is required to operate at a temperature of approximately 500 degrees Celsius in the vast majority of cases. Not only does it have to contend with the consequences of increased pressure, but it must also contend with the consequences of increased temperature. The result is that when selecting an aluminum alloy die-casting factory to produce the die steel for the aluminum alloy die-casting die, certain requirements must be met in order to ensure a successful outcome.

It is possible to achieve excellent machinability.
Additionally, the majority of aluminum alloy die-casting molds require some cutting and fitter repair in order to function properly. This is in addition to CNC machine tool processing. It is critical to have the optimal hardness of steel for plastic molds in order to increase the life of cutting tools, improve cutting performance, and reduce surface roughness. When it comes to China die casting mold plants, where excessive consumption of cutting tools can result in tool failure, this is especially important.

The thermal stability of the material is excellent.
The shape and processing of die-casting die parts made of aluminum alloy are frequently complex, making them difficult to process after they have been quenched. In order to avoid this, it is critical to select components that have high thermal stability to the greatest extent possible. As long as the die's dimensional accuracy and surface roughness requirements are met, the aluminum alloy die-casting die can be reduced in size or eliminated entirely due to the alloy's low linear expansion coefficient, low heat treatment deformation, low size change rate caused by temperature difference, and stable metallographic structure and die size after it has been formed and processed following the heat treatment process.

Exceptional polishing results are achieved.
In order to produce high-quality aluminum alloy die castings, a low roughness value of the cavity surface is essential. The aluminum alloy die casting factory must therefore polish its cavities in order to reduce the surface roughness values of the aluminum alloy die castings. The steel that was selected requires fewer impurities, has a fine and uniform structure, does not exhibit fiber directivity, and does not develop pitting or orange peel defects during the polishing process, among other characteristics.

Sufficient surface hardness and wear resistance on the surface
Mold rigidity must be maintained after heat treatment, so that the mold's surface hardness is sufficient to ensure that the mold retains its rigidity after heat treatment. During the filling and flow of aluminum alloy liquid, which must withstand significant pressure and friction, it is essential that the die maintain the stability of shape accuracy and dimensional precision, as well as the ability to maintain a sufficient service life throughout the work cycle.

The chemical composition of the steel, as well as the hardness achieved through heat treatment, are responsible for determining the wear resistance of a die set. Therefore, increasing the hardness of the die is advantageous in terms of increasing the wear resistance of the die itself.

When selecting materials, it is also important to consider the likelihood of scratching and gluing. If there is a significant amount of relative movement between the two surfaces, avoid selecting materials that have the same organizational structure as the two surfaces. Plating or nitriding one side of the component can be used to create a difference in surface structure between the two sides in some cases.

A suggestion has been made that the zinc slag produced by the die casting factory not be treated by the factory itself. As a result of the large amount of smoke and dust produced by zinc slag smelting, it is necessary to make a significant investment in environmental protection equipment, which comes at a high financial cost. Two-fold reason: When the smelting process and operation are not standardized, it is easy for the quality of the alloy material to be compromised, which results in a high number of casting defects produced by die casting and a higher overall production cost.
