Sheet metal shell is a type of product shell made by processing thin metal sheets, which has multiple uses and characteristics.
definition
Sheet metal shell is a comprehensive cold working process for metal sheets (usually below 6mm), including cutting, punching/cutting/composite, folding, welding, riveting, splicing, forming, etc. Its notable feature is that the thickness of the same component is consistent.
application
Sheet metal shells are widely used in fields such as electronics, communications, automotive industry, medical equipment, etc., such as chassis cabinets, large industrial equipment, charging stations, etc. They provide protection, support, and aesthetics for various devices and equipment.
Material Science
The materials used for sheet metal shell processing include:
1. Cold rolled sheet (SPCC): Low cost, easy to form, but prone to rusting, usually requiring surface treatment.
2. Galvanized sheet (SECC/SGCC): It has good corrosion resistance, is easy to form, and has a relatively high cost.
3. Hot rolled plate (SPHC): Low cost, but difficult to form, usually used for thicker flat plates.
4. Copper: Mainly used as a conductive material, it has a high cost and usually does not undergo surface treatment.
5. Stainless steel (such as SUS304): It has good corrosion resistance and usually does not require surface treatment.
6. Aluminum plate or aluminum alloy: low density, light weight, good conductivity, thermal conductivity, and corrosion resistance.
The design and manufacturing of sheet metal shells need to consider the processability of materials, surface treatment status, as well as the purpose and cost of the final product. By selecting appropriate materials and processing techniques, sheet metal shells can meet the performance and appearance requirements of different industries.
