Aluminum castings are equipment parts made of pure aluminum or aluminum alloy by casting. Aluminum or aluminum alloy heated in liquid is usually poured into the mold with sand or metal mold. Aluminum castings or aluminum parts of different shapes and sizes are called aluminum die casting. What is the modern molding technology of aluminum castings? Let's analyze it.

Complex aluminum casting parts with electromagnetic pump low-pressure casting technology as the core, aluminum smelting and mold plastic purification technology as the core of the new manufacturing technology, modern technology for the production of aluminum casting parts. The electromagnetic pump low-pressure casting metal melt conveying system has stable flow and convenient flow control, which reduces the back suction of alumina melt and realizes the advantage of automatic use of the process. This can not only improve the casting quality of aluminum castings, but also improve the working environment. Reduce labor intensity, realize automation and modernization of aluminum casting production.

In addition to gas injection and spinning foam ceramic filters and high degassing, high-performance metal debris, an important part of refined enamel alloy castings is aluminum smelting and composite purification facilities. In addition, aluminum castings use new long-life lining materials, with independent insulation/Heating system, which can be used for large-scale continuous production or intermittent production. The technology has the advantages of high purification efficiency, long life, low cost, convenient installation and flexible use.

From the modeling of the aluminum casting core manufacturing process, it can be seen that it directly affects the quality and output of aluminum casting. The porosity of castings, sand adhesion, and hot cracks have a good relationship with surface quality, dimensional accuracy and sand mining performance. The new modeling manufacturing process is used for the core resin binder of zircon sand resin, which is a difficult self-hardening sand mechanism independent, non-curing chemical reaction has just begun to harden, and the curing reaction will accelerate. Once accelerated, high strength and low fat gas decay, so the complexity of the casting surface ensures the dimensional accuracy and stability of the quality.

Advantages of aluminum casting:

It can produce parts with complex shapes, especially blanks with complex cavities (such as heating).

Aluminum casting has wide adaptability and can be used for all metal materials commonly used in the casting industry.

A wide range of raw materials for aluminum casting. The shape and size of low-cost scrap steel and scrap steel are very close to the parts, and almost no machining is performed to reduce the amount of cutting.
