1. Overview

Sheet metal processing is a type of metal sheet processing technology, widely used in manufacturing industries such as machinery, automotive, aerospace, and home appliances. The main purpose of sheet metal processing is to produce the required product parts by cutting, bending, and forming metal sheets. Its four major processes are the foundation and core of sheet metal processing, ensuring the quality and performance of the products.

2. The Four Major Processes

1. Cutting Process

Cutting is the first process in sheet metal processing, mainly including manual cutting and mechanical cutting methods. The main purpose of the cutting process is to cut the metal sheet into the required shapes and sizes according to the product design. During cutting, it is necessary to ensure the cut edges are flat and smooth to avoid affecting subsequent processes.

2. Bending Process

The bending process is a very important step in sheet metal processing. Using a bending machine or other equipment, the metal sheet is bent to the required angle and shape. The bending process requires precise control of the angle and bending radius to ensure the accuracy and appearance of the product.

3. Forming Process

The forming process is one of the most complex processes in sheet metal processing. Through stamping, stretching, compression, and other methods, the metal sheet is processed into various complex shapes and structures. The forming process requires a high level of technical skill and precise control to ensure the quality and performance of the product.

4. Welding and Assembly Process

Welding and assembly are the final steps in sheet metal processing. Welding is used to connect various parts together to form a complete product. During assembly, it is necessary to ensure the accurate and firm positioning of each part to guarantee the stability and reliability of the product.

3. Summary

The four major processes of sheet metal processing—cutting, bending, forming, welding, and assembly—are the foundation and core of sheet metal product manufacturing. Each process requires precise control and a high level of technical skill to ensure product quality and performance. With technological development, sheet metal processing technology is continuously advancing, and more new technologies and processes will be applied in the future, bringing more innovation and transformation to the manufacturing industry.
