　　Welding shell is a popular method of shell manufacturing. The advantages of welding shell are: low manufacturing costs, high strength. In general, the cost of welding aluminum shell is 2-3 times that of injection molding. Welding technology can maximally realize the strength of aluminum material. The tensile strength of aluminum material is 5 times that of iron and 2 times that of steel.

　　The high strength of aluminum shell can meet the high strength requirements of electronic products, and the good thermal conductivity of aluminum material can better protect electronic products. It is precisely because of this that welding shell is increasingly adopted by the electronics industry. Next, let's see how to make high performance aluminum extrusion shell.

　　Advantages of aluminum extrusion shell

　　Compared with injection molding, aluminum extrusion has the following advantages:

　　1. High elongation, various complex aluminum extrusion shells can be manufactured according to the shape and size requirements of products.

　　2. Stable quality, stable quality of aluminum extrusion shell can be guaranteed.

　　3. Low cost, because the forming process of aluminum extrusion shell is simple, the cost is low.

　　4. Simple structure, simple structure of aluminum extrusion shell, convenient installation and use.

　　Production methods of welding aluminum shell

　　1. Preparation before welding

　　The preparation work for welding aluminum shell mainly includes the following aspects:

　　1. Determine welding method and welding process

　　2. Select welding materials
