Aluminum Casting Performance
Aluminum casting refers to the equipment of pure aluminum or aluminum alloy which is obtained by casting. Generally, the aluminum or aluminum alloy parts or aluminum parts of aluminum parts or aluminum alloy parts are usually referred to as aluminum die casting.
Aluminum casting modern molding technology
Complex aluminum casting foundry is a kind of electromagnetic pump low pressure casting technology as the core, aluminum smelting and molding compound purification technology and new technology with the core of manufacturing, production of high quality aluminum castings modern technology. Electromagnetism pump low pressure casting metal liquid and the transmission system has a stable flow, flow control, convenient and ease the process of fused alumina indrawn breath and easy to automate is the use of the advantages of the process, it is not only the improvement of casting quality aluminum metal casting, and can also improve the working environment. Reduce labor intensity, realize automation and modern casting production.
The important components of the purified melt enamel alloy castings are aluminum smelting and composite purification facilities besides the gas injection and spin foam ceramic filters and high degassing, unless the properties of metallic inclusions. In addition, it USES a new long life lining material, which can be used for a large number of continuous production, as well as intermittent production. This technology has high efficiency, long life, low cost effective, easy to install, use and flexible. The casting experience tells us that the quality of aluminum castings to solve complex problems is in three main aspects:
(1) smelting and melting of aluminum,
(2) smooth transition molten aluminium metal halide lamp
(3) the size and stability of mold and sand core process.
Core manufacturing process modeling can see the casting quality and yield have a direct impact. The relationship between casting porosity, viscous sand, scar, thermal cracking and surface quality and dimension accuracy is very good. Modeling and manufacturing of new technology is the core PEPSET resin binder used for the original zircon sand sand resin sand from hard, difficult the process and the mechanism of an independent, non hardening reaction at first, it is time to start the hardening, once you start fast curing reaction. So coach bag, because in a tough, high intensity, fat gas collapse small, good performance is the complexity of the casting surface to ensure the quality and stability of the dimension precision.
Performance and application
Casting aluminum alloy has the incomparable advantage over other castings, such as beautiful, light quality, corrosion resistance and other advantages, make it widely popular with the users, especially in the automotive lightweighting, casting aluminum alloy castings has been widely used in the automotive industry.
The density of cast aluminum alloy is smaller than cast iron and cast steel, but higher than strength. Therefore under the same load conditions using aluminum alloy castings, can reduce the weight of the structure, so in the aviation industry and machinery and transport machinery, widely used in the aluminum alloy castings. The aluminum alloy has a good surface gloss and has good corrosion resistance in the atmosphere and fresh water. Therefore, it is widely used in the manufacture of civilian utensils. Pure aluminum has good corrosion resistance in nitric acid and acetic acid such as acetic acid, so aluminum castings are also used in chemical industry. Pure aluminium and aluminium alloy with good thermal conductivity, in the heat exchange device used in the chemical production, and has good thermal performance required in the machinery parts, such as internal combustion engine cylinder cover and piston, also suitable for made from aluminum alloy.
Aluminum alloy has good casting performance. Due to the low melting point (pure aluminium melting point of 660.230 C, the pouring temperature of aluminum alloy in general about 730 ~ 750 oc), therefore, can be widely used in metal mold and die casting foundry method, in order to improve the casting inherent quality, dimensional accuracy and surface is bright and clean degree and production efficiency. Aluminum alloy, because of the large latent heat of solidification under the condition of the same weight, the solidification process of liquid aluminum time continue much longer than cast steel and cast iron, good liquidity, casting thin wall and complex castings.
Casting of aluminum alloy castings have many advantages, make it become the development direction of the casting industry and one of the most popular casting products procurement customers, along with the progress of the aluminum alloy casting technology in the future, it will be a bigger stage to show their elegant demeanor.
