Introduction to Sheet Metal Processing: Techniques and Tools for Precision

Sheet metal working is a metal working process widely used in the manufacturing industry, mainly for the production of thin sheet metal parts, such as car bodies, home appliance housings, electronic equipment chassis and so on. Sheet metal working technology not only requires precise process control, but also the use of efficient tools and equipment. In this article, we will introduce the basic process of sheet metal processing, key technologies and commonly used sheet metal tools in detail, which will help you master the core points of sheet metal processing, thus improving production efficiency and product quality.

I. Basic Process of Sheet Metal Processing

Sheet metal processing generally has the following basic process:

Material selection: According to the product performance, strength, corrosion resistance and other requirements, select cold rolled sheet, stainless steel, aluminium and other suitable metal materials.

Material: According to the design drawings, using shears, laser cutting machines and other equipment, cut the plate into the required shape.

Punching : Use punching machine to process the designed holes, slices, slots and other structures on the plate.

Bending : With the help of a bending machine, the sheet is bent into a three-dimensional shape according to the designed angle and shape.

Welding : Multiple sheet metal parts are welded together to form a whole structure, forming the main body of the product.

Surface treatment : Surface treatment by spraying paint and electroplating to improve the corrosion resistance and appearance quality of the product.
