Nine Main Points Of Aluminum Boxes Stamping

Aluminum has the characteristics of light weight, good heat dissipation, easy processing, and excellent corrosion resistance, so electronic equipment  is widely used. The enclosures of many equipment are made of aluminum, and most of the aluminum alloy enclosures are obtained by secondary processing of aluminum alloy plates. In mass production, the processing of aluminum alloy  enclosures is mainly based on stamping.

During stamping production, the aluminum alloy  enclosure is particularly prone to be crushed and scratched. Therefore, in the process of mold making and stamping production of aluminum alloy  enclosure, the following nine points should be paid attention to:

First, the aluminum alloy material is soft, in order to prevent the deformation and displacement of the aluminum alloy during the stamping process. Precise positioning must be set on the stamping die, and the positioning device needs to have a smooth surface without water chestnuts. This can effectively reduce the defects caused by the stamping of the aluminum alloy  enclosure.

Second, reasonably design the mold gap to prevent the aluminum alloy enclosure from bulging and slumping.

Third, when designing the structure of the aluminum alloy  enclosure, try to avoid deep sinking holes, because most of the post-processing of the aluminum alloy  enclosure requires anodizing, and the deep sinking holes are easy to hide acid during anodization.

Fourth, all the edges of the mold should be cut with slow-moving wires, because the edges of the molds cut by the fast and medium-moving wires are not flat, and burrs and dog teeth are prone to occur at the position of the edges of the aluminum alloy  enclosure during stamping.

Fifth, when the aluminum alloy  enclosure is stamped, the aluminum alloy sheet needs to be pasted with a pe film. Pe film can effectively reduce scratches and crush injuries.

Sixth, in the production process, it is necessary to keep the mold, stamping platform, and transfer blister tray clean and free of impurities.

Seventh, aluminum alloy is a good conductor of heat, which is easy to conduct heat and generate heat. Therefore, it is necessary to frequently apply drawing oil on the material and mold to cool down during stamping, which can also play a lubricating role.

Eighth, during production, if the aluminum alloy casing has too large burrs or collapsed edges, it is necessary to contact the mold department as soon as possible to repair the mold before production.

Ninth, when the aluminum alloy enclosure is stamped, the operator should tear off the pe film every 20-30 pieces to check whether the aluminum alloy  enclosure has poor stamping, such as: Mold printing, crushing, scratching, bulging, slump, curling .
