Antarctica has this brand, which mainly produces body covering parts, such as fenders, front and rear hoods, etc.
Automobile sheet metal (Metal Plate; SheetMetal in English) is a technical means of automobile repair. In this aspect, automobile sheet metal is equal to automobile sheet metal repair, which refers to the repair of the car body after a collision, that is, All work except for the anti-corrosion and decorative painting work on the body. Such as automobile body damage analysis, automobile body measurement, automobile body sheet metal shaping, stretch correction, stress relief welding, and automobile body accessories assembly and adjustment, etc.
1. Sheet metal materials must have good plasticity. It must have the ability to produce permanent deformation without being damaged under the action of external forces. For cold-worked parts, it must have good cold plasticity, such as automotive stamping parts; for hot-worked parts, it must have good thermoplasticity, such as hot-forged spring steel plates, hot rivets, etc.
2. Good solderability. Many automotive sheet metal parts are welded together by spot welding, oxygen welding, arc welding or gas shielded welding, so sheet metal parts are required to have good welding performance. This is especially important in automobile excavation and repair. Materials with good weldability have high welding strength and low tendency to crack.
3. Low price. For any component of the car, economy should be considered as long as the working conditions are met. If you can use ferrous metals, don't use non-ferrous metals; if you can use non-ferrous metals, never use precious metals. The lifespan of automobile sheet metal components should be compatible with the lifespan of other automobile components.
4 Good chemical stability. Most automobile covering parts work in an open-air environment and are often in contact with water and steam. Especially like mufflers, they often work under higher temperatures and corrosive gases. This requires sheet metal parts to have good chemical stability, which requires corrosion resistance and strong anti-rust ability at room temperature, and also requires not to be corroded or deformed under high temperature or sun exposure.
5. Good dimensional accuracy and intrinsic quality of the plate. The dimensional accuracy and inherent quality of the plate have an impact on sheet metal processing. The impact is huge, especially on molded parts.
