Aluminum castings are widely used, which can make the castings run faster and improve the production efficiency. It has various shapes and sizes for users to choose. What technology does it use in production and processing?
1. Electromagnetic Pump Low Pressure Casting Technology Electromagnetic Pump Low Pressure Casting Metal Melt Transport System has a stable flow. The advantages of alleviating the inverted suction of molten alumina in the process and being easy to realize are the automation of the use process. This not only improves the casting quality of aluminium castings, but also improves the working environment.
2, an important part of the purified fused enamel alloy casting is aluminum smelting and composite purification facilities in addition to gas injection and spin foam ceramic filters with high degassing unless the performance of metal inclusions. It uses a new long-life lining material and has an independent thermal insulation or heating system that can be used for mass continuous production as well as intermittent production.
3. Resin binder used in original zirconium sand is from hard sand. The difficult self-hardening sand mechanism is an independent, non-hardening chemical reaction. It's time to start hardening. Once the hardening reaction starts quickly. Good performance is the complexity of the surface of the castings, ensuring the quality and stability of the aluminium castings dimensional accuracy.
The use of parts pays attention to a precision. In order to make the aluminum castings meet the requirements, it will use many technologies to strengthen its quality and improve its accuracy, so as to better cooperate with the use of machinery.
Carrier films on the surface of aluminium castings have corrosion resistance, so they need not be further treated in many applications. Some mechanical methods, such as rolling aluminium castings with selected abrasives and polishing agents in drums, can achieve a good smooth surface. Polishing can make the surface of castings smooth and reflective, but the effect depends to a certain extent on the type of alloy and the hardness of aluminum castings. Shot peening can obtain a glossy surface, while wire brush can obtain a flat glossy surface. Some treatment methods, such as electroplating, painting and anodic treatment, can improve the anti-corrosion ability and make the appearance of the parts beautiful.
