The role of magnetic polishing-Aluminum Die Casting Properties
Aluminum die casting is an aluminum alloy part formed by injecting aluminum alloy liquid metal into the aluminum mold through pressure, and then rapidly solidifying. Compared with other casting methods, aluminum die castings have the following characteristics:
High precision: Aluminum die castings have high precision and high surface finish, which can reach the surface roughness of CT4-CT6 level, and are suitable for parts that require high precision and high surface quality.
Good thin-wall performance: Aluminum die-casting can be used to manufacture thin-walled parts with a thickness of 0.5-1mm, so the overall weight can be reduced and the rigidity and strength of parts can be improved.
Good corrosion resistance: Aluminum die castings have excellent corrosion resistance, can resist the corrosion of most chemical media and oxidants, and are suitable for the manufacture of components with high corrosion resistance requirements.
Good stability: The parts made of aluminum die castings have the characteristics of good stability and high dimensional accuracy, which can meet the requirements of complex shapes, high precision and mass production.
Strong plasticity: Aluminum die castings can adjust the alloy ratio and change the casting process parameters according to the needs to meet different industrial needs.
Aluminum die castings have the characteristics of high precision, high surface quality, good thin wall, good corrosion resistance, good stability and strong plasticity, so they are widely used in the manufacture of parts in the fields of automobiles, electronics, machinery, aerospace and other fields .
The role of magnetic polishing of aluminum die castings
Magnetic polishing of aluminum die castings is a common surface treatment method. It removes oxides, burrs, stains and other impurities on the surface of aluminum die castings by using a magnetic polishing machine, making the surface smoother and smoother, and improving the quality of aluminum die castings. surface quality and mechanical properties.
Specifically, there may be impurities such as oxide layer, scale, and burrs on the surface of aluminum die castings, which will affect its surface finish and flatness, and will also reduce the mechanical properties and corrosion resistance of aluminum die castings. Using a magnetic polishing machine for surface treatment can effectively remove these impurities, making the surface of aluminum die castings smoother and flatter, and at the same time improving the corrosion resistance and mechanical properties of aluminum die castings and prolonging their service life.
In addition, magnetic polishing of aluminum die castings can also improve its appearance quality, making its surface smoother and brighter, suitable for applications that require high surface quality. In addition, magnetic polishing of aluminum die castings can also remove tiny cracks and defects on the surface, thereby improving the service life and reliability of aluminum die castings.
In short, the role of magnetic polishing of aluminum die castings is to remove surface impurities, improve surface finish and flatness, improve appearance quality, improve the mechanical properties and corrosion resistance of aluminum die castings, thereby improving the service life and reliability of aluminum die castings.
