Problems in the production of aluminum alloy housings
With the highly stable development of industrialization to modernization, the demand for energy-saving and environmentally friendly products is increasing day by day. Due to the characteristics of low density, low melting point, good processing performance, excellent electrical conductivity and corrosion resistance, aluminum alloy is the preferred material for energy saving, weight reduction and environmental protection products. The corresponding aluminum alloy shell products have also become the darling of modern product shells. So which parts of the aluminum alloy shell are more prone to problems in the production process? The following is the sharing of the balford metal stamping editor.
The parts that are prone to problems in the production of aluminum alloy casings are as follows:
- Due to the improper design of the stamping die: the pressure injury caused by the die itself, the die is too tight, the parts need to be pryed, and the gap caused by prying.
- Bumps during stamping and CNC processing: improper operation, the aluminum alloy shell touches the mold fixture, machine tool equipment, etc. when the part is taken out, the processed aluminum alloy shell is not placed in time and stacked together; improper operation, aluminum alloy shell Alloy casing dropped.
- Bumps and scratches during the flow of each process: improper stacking and collapse, the aluminum alloy casing is vigorously held and placed, and there are debris in the packaging material of the aluminum alloy casing. During the transfer process, the debris and the product friction cause scratches.
- Caused by improper anodizing operation: when the anodizing is hung up and down, it is caused by the hanger; when it is in and out of the tank, it is caused by the oxidation tank; the product is dropped.
As can be seen from the brief description above, the machining process of the aluminum alloy shell is not simple and smooth. In the process, various accidents and problems will still be encountered. Therefore, it takes a lot of attention and effort to make a finished and high-quality shell.
8 main points of stamping and stretching of aluminum alloy housing
In mold production, the processing of aluminum alloy housing is mainly stamping. The aluminum alloy shell is particularly prone to being crushed and scratched during the stamping production process.
Therefore, in the process of mold manufacturing and stamping production of aluminum alloy shells, the following nine points should be paid attention to:
- First, the aluminum alloy material is soft to prevent deformation and displacement of the aluminum alloy during the stamping process. Precise positioning must be set on the stamping die, and the positioning device requires a smooth surface without water chestnuts. This can effectively reduce the defects caused by the stamping of the aluminum alloy casing.
- The second is to reasonably design the mold gap to prevent the aluminum alloy shell from bulging and slumping.
- Third, when designing the structure of the aluminum alloy casing, try to avoid deep holes, because most of the aluminum alloy casing art requires anodization, and the deep holes are easy to hide acid during anodization.
- Fourth, all the edges of the mold should be cut with a slow wire, because the edges of the mold cut by the middle wire are uneven, and burrs and dog teeth are prone to burrs and dog teeth at the edge of the aluminum alloy shell during stamping.
- Fifth, when the aluminum alloy shell is stamped, the aluminum alloy sheet needs to be pasted with PE film. PE film can effectively reduce scratches and pressure 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 thermal conductor, which is easy to conduct and heat. Therefore, in the stamping process, it is necessary to frequently apply aluminum alloy stamping and drawing oil on the material and mold for cooling, which can also play a role in lubrication.
- Eighth, in the production process, if the aluminum alloy shell has too large burrs or edge collapse, you should contact the mold department for mold repair as soon as possible.
