What are the characteristics and requirements of aluminum profile shell processing?

In our daily life, the application of aluminum alloy shell is still very wide, such as mobile power shell, camera shell, vehicle controller shell, signal enhancer shell, power box shell, digital shell, shielding box shell... etc. Most of them use aluminum alloy shell. Aluminum alloy products have become one of the mainstream products in the electronics industry. Various shells made of aluminum alloy materials are widely used in the electronics industry because of their convenient processing, high flexibility and high grade, which can effectively improve the added value of products. They usually include aluminum profile shell processing and aluminum die-casting shell processing. So what are the characteristics of aluminum profile shell processing? The small edition of Sheet Metal Processing manufacturer will introduce it to you.

The characteristics of aluminum profile shell processing:

1. Aluminum has good electrical and thermal conductivity, second only to silver, copper, and gold.

The density of low-density aluminum and aluminum alloys is close to 2.7 g/h, which is about one-third that of iron or copper.

3. Easy to handle. After adding certain alloying elements, forged aluminum alloys with outstanding forging function or deformed aluminum alloys with good processing plasticity can be obtained.

4. High-strength aluminum and aluminum alloys have high strength. After a certain degree of cold working, the matrix strength can be strengthened, and some aluminum alloys can also be strengthened by heat treatment.

Requirements for aluminum cabinet processing:

1. For punching as far as possible in the back of the project without affecting the number of projects, even for products with a large number of punches, one more project can be considered to be punched in the back.

2, the aluminum material is soft and the mold is easier to block the material, so when designing the mold to put the gap, it is appropriate to put a gap of 10% of the thickness of the bilateral material.

3. When aluminum profiles are processed and bent, aluminum chips are easily generated during bending, which can cause scratches and indentations. The aluminum raw material needs to be pasted with PE film. In the case of rollers and electroplating, the molding block should be polished and plated with hard chrome.

4. Due to the brittleness of the aluminum material, it is easy to crack, especially in the case of anti-folding, so try not to make the pressing line. Even if you do, make the pressing line wider and shallower.

5. All aluminum parts are required to be cut with a slow wire to prevent burrs and unsmooth blanking. Aluminum parts are prone to high temperatures, so the hardness of the punch is required to be above 60, at least SKD11 material or more, and no D2 or other poor quality punches are allowed.

6, for the anode processing of the stamping parts, such as flattening, flattening process 180, the product can not be fully pressed, fully pressed will produce acid phenomenon, need to leave 0.2-0 seam, so that the acid flow out in time, so in this process must be done and the limit block calibration die higher than the mold.
