What is aluminum die casting?

Aluminum die-casting refers to aluminum parts of pure aluminum or aluminum alloy obtained by casting. Yleisesti, a sand mold or a metal mold is used to pour the heated liquid aluminum or aluminum alloy into the mold cavity, and the aluminum parts or aluminum alloy parts of various shapes and sizes obtained are usually called aluminum die castings.

Aluminum die casting technology
Aluminum casting is a modern molding technology
The complex casting of aluminum castings is a kind of low pressure casting technology with electromagnetic pump as the core. The composite purification technology of aluminum smelting and molding is a new technology at the core of the aluminum die-casting industry, a modern technology for producing high-quality aluminum castings. The electromagnetic pump low pressure casting molten metal transmission system has a stable flow and convenient flow control. The advantage of alleviating the suction process of molten alumina and easy realization is the automation of the use process, which not only improves the casting quality of aluminum castings, but also improves the working environment. Vähennä työvoiman intensiteettiä, realize automation and modern casting production.

An important part of the purification of molten enamel alloy castings is the 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. Lisäksi, it uses a new long-life lining material and has an independent heat preservation/heating system that can be used for a large number of continuous production, as well as intermittent production. The molten aluminum purification technology of this technology is high in efficiency, long life, halpa, effective, easy to install, use and flexible. Casting experience tells us that the quality of aluminum castings to solve complex problems is in three main aspects:
(1) Melting and melting of molten aluminum,
(2) Smooth transition of molten aluminum metal halide lamp
(3) The size and stability of the mold and sand core process.

Core manufacturing process modeling can see that casting quality and output have a direct impact. Casting porosity, sticky sand, scars, thermal cracking, pinnan laatu, dimensional accuracy, and sand performance have a very good relationship. The new technology for modeling and manufacturing is PEPSET. The core resin binder used in the original zirconium sand sand has an independent, non-hardening chemical reaction mechanism initially from hard sand to hard sand. It's time to start hardening, once the curing reaction starts fast. In a tough, voimakas, gas fat collapse small, good performance is the complexity of the casting surface, dimensional accuracy and quality stability.

Performance and application of aluminum die casting
Cast aluminum alloy has some advantages that other castings cannot match, such as beautiful appearance, light weight, korroosionkestävyys, jne., making it widely favored by users. Especially since the lightweight of automobiles, cast aluminum alloy castings have been widely used in the automobile industry.

The density of cast aluminum alloy is lower than that of cast iron and cast steel, but its specific strength is higher. Siksi, the use of aluminum alloy castings under the same load conditions can reduce the weight of the structure. Siksi, aluminum alloy castings are widely used in the aviation industry, power machinery and transportation machinery manufacturing. Aluminum alloy has good surface gloss and good corrosion resistance in the atmosphere and fresh water, so it has a wide range of uses in the manufacture of civil utensils. Pure aluminum has good corrosion resistance in oxidizing acid media such as nitric acid and acetic acid, so aluminum castings also have certain uses in the chemical industry. Pure aluminum and aluminum alloys have good thermal conductivity. They are used in heat exchange devices used in chemical production, and parts that require good thermal conductivity on power machinery. Esimerkiksi, cylinder heads and pistons of internal combustion engines are also suitable for manufacturing of aluminum alloy.

Aluminum alloy has good casting properties. Due to the low melting point (the melting point of pure aluminum is 660.230C, the casting temperature of aluminum alloy is generally about 730-750C). It can be widely used type of metal casting and pressure casting and other methods to increase the intrinsic quality of the casting, the degree of dimensional accuracy and surface finish and productivity. Due to the high latent heat of solidification of aluminum alloy, the solidification process of molten aluminum lasts much longer than cast steel and cast iron under the same weight. It has good liquidity and is conducive to casting thin-walled and complex-structured castings.
Cast aluminum alloy castings have many advantages, making it one of the most popular casting products for the development direction of the casting industry and purchasing customers. In the future, with the advancement of aluminum alloy casting technology, it will show its style on a larger stage.
