With the advancement of science and technology in modern times, manufacturers pay more and more attention to the meticulous processing of sheet metal. Laser cutting technology is one of the methods of sheet metal processing. Sheet metal processing using laser cutting can meet the requirements of narrow slits, smooth and beautiful cutting surfaces, no dross, and high precision for metal processing according to the drawings given by customers.

Most of the processing of automobile sheet metal parts uses laser cutting technology. For example, people's daily travel tools and auto parts cannot be separated from sheet metal processing, or some large truck parts require high-precision metal iron sheets.

In automobile manufacturing and maintenance, the shape of many sheet metal structural parts is very complex. In order to avoid the difficulties of sheet metal, sheet metal materials must have good process performance requirements, namely:

1 Sheet metal materials must have good plasticity. It must have the ability to produce permanent deformation under the action of external force without being damaged. For cold work parts, it must have good cold plasticity, such as stamping parts of automobile parts; for hot work parts, it must have good thermoplasticity, such as hot forging spring steel plates, hot rivets, etc.

2 Good solderability. Many automobile sheet metal parts are welded together by spot welding, oxygen welding, arc welding or gas shielded welding, so the sheet metal parts must have good welding performance. This is especially important in car repair and maintenance, because materials with good weldability have high welding strength and low cracking tendency.

3 Low price, economical and practical. For any component of the car, economical efficiency should be considered under the condition of meeting the working conditions. Where ferrous metals can be used, non-ferrous metals are not used; where non-ferrous metals can be used, precious metals are never used. The life of automobile sheet metal components should be compatible with the life of other automobile components.

4 Good chemical stability. Most of the automotive panels work in the open air, often in contact with water and steam, especially like mufflers, which often work at higher temperatures and corrosive gases. This requires that sheet metal parts must have good chemical stability, which requires corrosion resistance and strong rust resistance at room temperature, and requires no corrosion or deformation under high temperature or sun exposure.

5 Good dimensional accuracy and intrinsic quality of the plate. The dimensional accuracy and intrinsic quality of the sheet metal affect sheet metal processing. The impact is great, especially for molded parts.
