Sheet metal shell processing is a common metal processing operation, usually used to manufacture various types of shells, boxes, bases and other products. Cum lapides metallicis processerint, sequentes gradus accipientur:

1. Design and drawing: First, it is necessary to design and draw the shell according to the requirements and specifications of the product. Design includes considerations of appearance, size, structure, and other aspects, while drawing is the process of converting design drawings into manufacturing process drawings.

2. Material preparation: Select materials suitable for processing. Commonly used materials include cold-rolled plates, hot-rolled plates, stainless steel plates, etc. Choose the appropriate material specifications according to product requirements.

3. Material cutting: Cut the material according to the process drawings and design requirements. Common cutting methods include cutting plates, stamping, laser cutting, etc., to obtain the required basic external dimensions.

4. Bending forming: According to the structure and requirements of the shell, materials are formed by bending or other methods to present the desired shape.

5. Welding connection: Weld the connection where it needs to be spliced to ensure that the structure of the shell is firm and the sealing is good. The commonly used welding methods include spot welding, submerged arc welding, argon arc welding, etc.

6. Surface treatment: Surface treatment is applied to the shell to achieve aesthetic, anti-corrosion, and increased wear resistance. Metodos superficie regionis usus sunt spraying, electroplating, polishing, etc.

7. Assembly and debugging: Assemble, debug, and test each component to ensure that the functionality and performance of the casing meet the design requirements.

Per supra gradus, perfecite processionem pellium metallorum et produktos cum artificie exquisite et qualitate fidelis. Sheet metal shells are widely used in industries such as electronics, communication, and machinery, and are an important component of product appearance and functionality improvement.
