As we all know, the conductivity and thermal conductivity of aluminum shell is very good. It is second only to silver, copper and gold. Therefore, many industrial shells will choose various shells made of aluminum alloy. Its aluminum shell has high flexibility, and its depth can be cut arbitrarily. Usually, there is a circuit board slot inside. As long as the circuit board is inserted directly, it does not need to be fixed again. Its speed is incomparable to other types of shells. The quality of aluminum alloy shell is often related to processing technology. What are the processing technologies of aluminum alloy shell?
Processing Technology Of Aluminum Alloy Shell
1. Internal High-Pressure Forming Technology
Internal high pressure forming (IHF) is a new forming technology for aluminum alloy shell processing, which has emerged in recent years, and is a research frontier in the world. According to their structural characteristics, various connecting pieces can be formed at one time by the internal high-pressure forming method, or they can be made into profiles by the general extrusion method, and then they can be straightened by the internal high-pressure forming method. The tube blank can be pressed into the mold cavity by internal pressurization and axial force supplement to form it.
2. Precision Die Casting Technology
The connecting pieces of the aluminum alloy body frame structure are usually formed by casting, and the casting methods used are mainly semi-solid die casting and other advanced high-precision die casting methods. At present, semi-solid die casting technology has two kinds of forming processes: rheological forming process and thixoforming process. The former is to send liquid metal into a specially designed injection molding machine barrel, which is sheared by a spiral device to cool it into semi-solid slurry, and then die cast. The latter is to send solid metal particles or scraps into the spiral injection molding machine, and make the metal particles become slurry under the conditions of heating and shearing before die casting.
The above contents are two common processing technologies for aluminum alloy shells. It is worth noting that different brands and models of products have different requirements for aluminum shells, specifically in shape, size and appearance treatment. Therefore, we can choose appropriate aluminum shell processing technology according to our actual needs.
