　　What is the formation process of aluminum shell?


　　Aluminum shell is a kind of common packaging shell. What is the forming process of aluminum shell? Let's follow the author to understand it today.


　　Due to the difficulties in manufacturing cold extrusion dies in China, a large number of aluminum and aluminum shells can only be formed by automobiles. It should be noted that the edges, corners and threads of automotive aluminum housing must be reversed to avoid sharp edges and burrs.


　　At the same time, the connecting ring of the aluminum shell should not wear cloth as far as possible. When salt spray is detected in the electroplated parts, the knurling part of the coating will inevitably corrode. In contrast, the corrosion degree of the salt spray detection of the straight roll joint ring is much lighter.


　　Due to the loose matrix of die casting, the porosity of electroless nickel plating is very high. As the chemical nickel layer is a cathode coating relative to the aluminum shell, once contacting with the corrosive medium in the air during the storage and use of the product, the corrosion of the aluminum shell substrate will be accelerated and the coating will blister and fall off.


　　There are many factors affecting the formation of aluminum shell, not only the process will affect the formation of aluminum shell, but also the production, design and use of materials will affect the formation of aluminum shell.
