Many car owners think that the body parts still need to be painted with the same color as the original car, so they will ignore the painting process of the body parts when choosing the body parts, which is irrelevant, but this idea is not correct. In order to prevent oxidation and corrosion, the body parts need to be painted before leaving the factory. Indeed, the painting link after replacing the body parts can not only color them, but also protect and prevent oxidation. However, if it is a small factory body parts, the painting treatment during production has uneven adsorption and foaming, which will affect the effect of post painting In the process of using, it is easy to fall off, lead to corrosion, affect and damage the quality of sheet metal parts.

In the automobile sheet metal processing industry, the use of lubricating oil is very important, because proper lubricating oil can make the machine use longer, lubricating oil during production can help better production, but it should be noted that the use of lubricating oil and lubricating methods, because improper use not only will not play a role may play the opposite role. As a result, we will take the lubrication of automobiles as an example to show you three major misconceptions in the use of lubricants.

Stamping process is one of the processing methods to complete metal plastic forming. External forces are usually exerted on sheets, strips, pipes and profiles by press and die to produce plastic deformation or separation, so as to obtain the required shape and size of the workpiece.

Stamping is a method of forming and processing parts (stamping parts) with required shape and size by applying external force to sheet, strip, pipe and profile by press and die to produce plastic deformation or separation. Stamping and forging belong to plastic processing (or pressure processing), which is called forging. Stamping blanks are mainly hot-rolled and cold-rolled steel sheets and strips.

Whether the die used for metal stamping parts is elastic pressure unloading plate or fixed unloading plate depends on the unloading force, and material thickness is the main factor to be considered. With the increase of elastic force of elastic components used in die (e.g. rectangular spring), the unloading force of elastic discharging plate is greatly enhanced. Hardware stamping is a method of forming and processing parts (stamping parts) with required shape and size by applying external force to sheets, strips, pipes and profiles by press and die to produce plastic deformation or separation.

Automobile sheet metal is a comprehensive cold processing technology for sheet metal (usually less than 6mm), including shearing, punching/cutting/composite, folding, welding, riveting, splicing, forming (such as automobile body), etc. Its remarkable feature is that the thickness of the same part is the same. The products processed by sheet metal process are called sheet metal parts. Sheet metal parts in different industries are generally different, and they are often used as appellations when assembling.
