As a part of computer accessories, its basic function is to place and fix various computer accessories, which has the effect of trust and guarantee. Furthermore, the red box is also crucial for magnetic shielding materials. Since the red box is different from CPU, discrete graphics card, computer motherboard and other spare parts, it can quickly improve the performance of the whole equipment, so DIY does not include the key consideration target. However, the box also has certain functions. Some users have a short circuit fault due to the circulation system between the computer motherboard and the box after purchasing fake containers, which makes the system software very unstable. What are the characteristics of the bending main chassis in the precision sheet metal factory?

1. design, material. Appearance and material are the basic characteristics of the box body. It is immediately determined whether a box body can be accepted by customers, so the appearance gradually tends to be diversified, thus occupying a certain proportion in our tests. The key to material selection lies in the common raw materials of the shell. Whether the edge of the shell is rolled or not, and the product quality of the raw materials is also directly related to its anti-electromagnetic radiation ability.

Second, extensibility. The direction of computer development is uncertain. The more complete the sheet metal laser cutting, the more it will be able to consider the future. The key point is to carry out accurate positioning of 5.25-foot computer optical drive, 3.5-foot floppy disk drive and computer hard disk drive.

3. features. To see if there is an external USB interface and audio input and output interface in the box, we will feel the software-free assembly of the main control board installed on the guide rails of the computer hard disk and computer optical drive.

4. dust-proof. For most consumers, dustproof is a problem that doesn't matter much, but if you want to keep the box clean for a long time, you have to see how dustproof it is. The dustproof performance of the heat dissipation hole and the dustproof performance of the expansion slot PCI partition were scientifically studied.

5. heat dissipation. The production of sheet metal processing is aimed at computers with strong heat dissipation capacity, and the heat dissipation capacity of the heat dissipation box cannot be ignored. Coupled with a large number of fans seems to be the popularity of DIY. In DIY, the key to consider how much money to save the heat dissipation fan and the heat dissipation hole.
