You drive every day, do you know how cars are made?

Cars have become an indispensable part of people’s daily lives. They drive or ride cars every day, but do you know how cars are produced? In fact, the car manufacturing process is not as complicated as people think. If the automobile production and installation processes are distinguished, there are a total of 4 steps: stamping, welding, painting, and final assembly. Each production detail of these four processes determines the quality of automotive products. Below we will give a general explanation of these four processes: First, stamping stamping is the first step in automobile manufacturing. Stamping is an important part of determining the quality of car body manufacturing. Good cars start with stamping. Stamping is the processing of steel coils into various stamping parts required by automobiles. In this production process, high-tonnage presses, precise stamping dies, and precise auxiliary tools are required. In addition, the performance of steel also affects stamping. An important factor in the quality of parts. Therefore, raw materials, presses and stamping dies are the three important factors affecting stamping, which affect the quality of stamping parts. In order to obtain better quality automotive stamping parts, we need to analyze from various aspects such as production organization, equipment status, mold status, etc. If we want to maintain the quality of automotive stamping parts, we must ensure the correct molding process and select good performance. Steel, guarantee the quality status of the stamping die, have reasonable quality control procedures and systems, the cleanliness of the steel surface, and the operating status of the press. 2. Welding and welding is the second step of automobile manufacturing. The basic process is to first press and weld the parts stamped in each first step, including the front and rear parts of the car body; then the floor The welding process of the line is completed here. The welding process of the left and right side of the car body is completed; after the floor part is welded, it enters the welding of the car body forming line. After this process, we can see that a car The prototype of the car has basically been born. During the welding process, it is necessary to ensure the stability of the overall structure of the welded car body, as well as the size of the car body to avoid over-tolerance. In the different structure of the car body, the welding method should be used correctly and reasonably. weld. The quality of welding plays an important role in the stability of the body structure, and it also prepares for painting. 3. Painting Painting is the third step in automobile manufacturing. The basic process flow is the surface treatment process before painting and the anti-rust primer painting process. First of all, it has anti-rust protection. 90% of a car is made of steel. If you don't paint the car, you can imagine it. The life of the car is greatly reduced, so it is necessary to paint the car. The paint process can protect the car from corrosion. With the introduction of new materials, the protective effect of the coating film is becoming greater and greater, such as: high scratch resistance, elasticity, pollution resistance, etc.; secondly, it can improve the beauty of the car and give it a beautiful appearance. Human beauty; it can reflect the orientation of customer values; finally, after the car is sprayed, it has a recognition effect. Fourth, final assembly Final assembly is the last step in automobile manufacturing. Various parts, components, assemblies or assemblies are connected in accordance with prescribed technical conditions and quality requirements to form a completed automobile product. Assembly is an indispensable last process in automobile production. Without assembly, there is no complete automobile, which plays an important role. First, assembly will ultimately check the manufacturing quality of parts; secondly, assembly can find weak links in automobile production; finally, assembly will ultimately affect product quality. Among the above four production steps, only stamping belongs to discrete manufacturing, and the other three belong to assembly line manufacturing. The different manufacturing and production methods lead to different management methods and means. A qualified car is produced through these four steps, and then it reaches the consumers through the sales channel.
