Sheet metal is the main material of the metal enclosure,
and its processing technology has a great influence on the appearance and performance of the chassis. In the processing of sheet metal chassis, various sheet metal materials are needed, among which stainless steel, galvanized sheet and aluminum sheet are the most common. These materials are the mainstream materials in the current sheet metal market and the most used materials, which can support sheet metal processing operations of various metal parts. Of course, these materials have different characteristics and scopes of application, and need to be selected according to specific needs. Especially in the foreign trade industry, different national regions have strict requirements on the selection of materials, such as certification, environmental protection, etc. You can see the following introduction:
1. Stainless steel is a common sheet metal material with high hardness,
good wear resistance, strong corrosion resistance, and not easy to deform. Therefore, it is suitable for making chassis shells with high strength and appearance requirements. However, the price of stainless steel is relatively high and the processing is difficult, so when choosing to use stainless steel materials, it is necessary to weigh them according to actual needs.
2. Galvanized sheet is a steel sheet with galvanized surface.
It has high surface hardness, good wear resistance, strong corrosion resistance, and relatively low price. Therefore, it is widely used in the production of chassis shells. However, the disadvantage of galvanized sheet is that it is easy to scratch and deform, which needs to be controlled during the processing.
3. Aluminum sheet is a lightweight,
high-strength material with excellent thermal conductivity and corrosion resistance, so it is suitable for making chassis shells that need heat dissipation. However, the hardness of aluminum sheet is low, the processing is difficult, and the price is high, so when using aluminum sheet, it is necessary to weigh it according to actual needs.
In addition to the above three materials, there are some other sheet metal materials, such as carbon steel sheet, copper sheet, etc. These materials have their own characteristics and need to be selected according to specific needs.
After selecting the appropriate sheet metal material, precise processing is required. The processing process includes shearing, stamping, bending, welding and surface treatment. These processes require strict quality control and technical requirements to ensure that the chassis has a beautiful appearance, reasonable structure and stable performance. Of course, sheet metal factories basically support these operating processes. Don’t worry about this. If you encounter a process that cannot be met, the sheet metal enclosure factory will inform you in advance. Let’s take a look at the specific functions of these processes:
Shearing is the first process in sheet metal processing, and its purpose is to cut the original sheet metal material into the required shape and size. The shearing process requires high precision, high efficiency and high stability to ensure the consistency of the material and the processing accuracy.
Stamping is a process method for processing metal sheets into the required shape and size. In the processing of chassis shells, the stamping process is mainly used to make holes and protrusions of various shapes. The stamping process requires high mold precision, uniform and stable pressure to avoid problems such as deformation and cracks.
Bending is a process method for bending metal sheets into the required angle and shape. In the processing of chassis shells, the bending process is a very critical link, and the angle, position and sequence of the bending need to be precisely controlled to ensure the appearance and performance of the chassis. At the same time, the bending process also needs to pay attention to the elastic and plastic properties of the material to avoid problems such as cracks and fractures.
Welding is a process method for connecting metal sheets together. In the processing of the chassis shell, the welding process is a very important link, and the quality and stability of the welding need to be strictly controlled to ensure the sealing and strength of the chassis. The welding process needs to pay attention to the weldability of the material and the setting of the welding parameters to avoid problems such as cold welding, leaking welding and uneven welds.
Surface treatment is a process method for painting, electroplating and spraying the chassis shell. Surface treatment not only affects the appearance quality of the chassis, but also has an important impact on its corrosion resistance and thermal conductivity. The surface treatment process needs to be selected according to the characteristics of the material and the use environment to ensure the performance and life of the chassis.
The selection of materials for the processing of chassis precision sheet metal parts and the control of the processing technology have a great impact on the quality and performance of the chassis. In the production process, the quality of the materials and the stability of the processing technology need to be strictly controlled to ensure that the quality and performance of the chassis meet the requirements.
