Part one: Sheet metal cutting technology
Using a shearing machine to cut sheet metal materials into the required shape and size is one of the most basic methods of cutting. Laser cutting uses high-energy laser beams for precise cutting, which is suitable for parts with high precision requirements. A high-energy-density laser beam is used to irradiate the metal plate to quickly heat the material to a melted or vaporized state, thereby achieving the cutting process. Compared with traditional mechanical cutting, this technology is more efficient and precise, and the cutting edges are neat and smooth, reducing the workload of subsequent processing.
Part Two: Sheet metal bending and bending technology
Through sheet metal bending and bending technology, flat metal sheets are transformed into three-dimensional structures with certain angles and shapes. The bending process is often used to make boxes, shells, etc. Precisely controlling the angle and curvature of the bend is critical to maintaining the geometry of the part, requiring appropriate selection of bending equipment based on material thickness, bend size and bend radius.
Part Three: Sheet metal punching and drawing processes
Punching refers to the use of presses and dies to make precise holes in metal sheets. During the punching process, you need to pay attention to the minimum size requirements. Generally speaking, the minimum size of the punching hole should not be less than 1mm to ensure that the punch will not be damaged due to the hole being too small. Hole drawing refers to enlarging existing holes or forming holes in new locations by stretching. Drilling can increase the strength and ductility of the material, but it also needs to take into account the properties and thickness of the material to avoid tearing or deformation.
Part Four: Sheet metal welding technology
Sheet metal welding is an important link in metal processing, which involves joining metal sheets together by welding to form the desired structure or product. Commonly used welding processes include MIG welding, TIG welding, beam welding and plasma welding. Each method has its specific application scenarios and technical requirements. Choosing the appropriate welding method is crucial to ensuring product quality and performance.
Part Five: Surface treatment
Choosing the appropriate surface treatment is critical to ensuring the performance and longevity of your sheet metal products. Surface treatment is a process designed to improve the appearance and performance of metal sheets, including drawing, sandblasting, baking, powder spraying, electroplating, anodizing, silk screen and embossing. These surface treatments not only improve the appearance of sheet metal parts, but also provide additional functionality such as rust protection, corrosion protection and enhanced durability.
