The body structure and material of automobile have changed a lot, and the application of load-bearing body has been gradually promoted. Therefore, the requirements of body repair technology are getting higher and higher. The repair process of automobile sheet metal parts not only requires the recovery of the shape of the automobile body, but also ensures that the performance of the repaired body is close to the state before the automobile damage, so as to avoid the occurrence of secondary accidents.

In the processing of automobile sheet metal parts, we need to pay attention to several problems. First of all, the staff should check the materials before processing, and unfold the materials for processing. The unfolding method of the materials should be correct, so that the materials can be saved and the processing purpose can be achieved. During the processing, we should also pay attention to the selection of the gap and the edge wrapping effect of the materials.

During sheet metal processing, the staff should understand the production process and processing methods, so that they can better complete the processing task and ensure the production of the workpiece.

Continuous die: also known as "progressive die", it refers to the die that completes two or more stamping processes at the same time in different positions in the process of a stamping stroke. This kind of die is difficult to maintain and needs experienced fitter to operate, but it has high production efficiency, can save labor and time cost, and has low scrap rate of precision metal stamping parts.

In order to prolong the service life of stamping parts and avoid corrosion and rusting, the corresponding anti-corrosion treatment is generally done

Preheating the workpiece before spraying can improve the adhesion of asphalt paint and accelerate the drying.
