There are two kinds of surface treatment methods commonly used in the processing of automobile sheet metal parts: electroplating and spraying. Electroplating is divided into galvanizing, nickel plating, chromium plating, etc. the main purpose is to form a protective layer of metal or alloy on the surface of sheet metal workpiece by using the principle of electrolysis, which plays a role of protection and decoration. Spray can be divided into spray painting and powder spraying. After the material parts are pretreated, the spray gun gas is used to disperse the coating into uniform and fine droplets, which are sprayed on the surface of the body work piece to form the coating on the surface of the work piece, and then heated and dried. Spraying can protect the workpiece. In addition to the above two methods, there are some other surface treatment methods, such as anodizing, chromate, wire drawing, sandblasting and oxidation.

When many users design new products or products for automobile stamping parts, they usually only pay attention to the development and development of products or the price at the initial stage, but do not pay much attention to the communication and communication with injection mould manufacturers. In fact, it is very necessary to communicate with injection mould manufacturers in advance after determining the preliminary design scheme of products. Today, we will give you specific information. Introduces the precautions for the opening of injection moulds.

It is said that the workers who make Lexus can feel the slight difference in the car body by hand. It is very difficult for us to reach the same level without professional training. But you should not worry too much. After all, a car that meets the factory standard is not easy to have the defects visible to consumers. Secondly, we also need to observe the clearance and smoothness between the various panels.

Product weight is one of the inspection standards to measure the quality of sheet metal parts. In order to ensure the safety of automobiles, the steel plates used in automobile sheet metal parts must reach a certain weight. The weight of the original sheet metal parts and the high quality by-products should be almost the same, and if the sheet metal parts you buy are one third lighter than the original sheet metal parts, then you will undoubtedly buy a small factory product.

Automotive sheet metal parts are widely used in various fields of our life, including some electronic devices, automotive parts, decorative materials and so on. Measuring method of metal automobile stamping parts: The hole measurement of metal stamping parts takes small value according to the general gauge measuring method. When recording with caliper measuring, it can generally record small value (excluding the error caused by too small value, analogy measuring error), (excluding special circumstances). It has no practical significance to record large value and average value, and it has no practical significance to measure the size of aperture in all directions. Differences should be recorded in the roundness of geometric tolerances, not in the aperture.

In the industrial field, different production processes will have a great impact on the performance of products. So, for the processing of stainless steel stamping parts, what are its processing characteristics and advantages? Next, automotive stamping parts manufacturers will analyze and answer this question, hoping to help you.

In order to realize the transformation, upgrading and development of automobile industry and improve the overall development level of automobile industry, China has proposed to vigorously develop energy-saving and new energy automobile industry. China's automotive parts industry must coordinate with the transformation and development of the entire automotive industry. In the future, it will focus on the development strategy of parts, transformation and upgrading, policy research, technological innovation, standards and regulations, zero cooperation, common platform construction, industrial internationalization, industrial cluster development and practical services.

The drawing oil for automotive parts belongs to metal processing oil, which is suitable for ultra-high strength stretch forming, pipe drawing, punching and shearing, broaching, etc. Stamping and drawing oils are divided into water-soluble, metal and aluminum stamping and drawing oils.

Careful observation of the automotive stamping parts produced will find that the surface of the product is concave and convex, thus affecting the quality of the whole workpiece. To improve this situation, we must first find the root cause of the problem, in order to formulate relevant solutions. Stamping parts manufacturers have also realized the seriousness of this problem, so they have begun to improve.

In our life, we often rust our daily necessities for some reasons, but there are the same problems in my sheet metal processing console. Because of the storage problem, when we put the sheet metal processing console in the basement, its humidity will be relatively high. After being damp, we should timely carry out moisture-proof and moisture-absorbing work on it.

In the production process of automobile sheet metal parts, there are certain requirements for stamping technology and stamping die. In high-speed stamping equipment and multi-function stamping die, only "high-speed" and "multi-function" can not meet the production requirements, only to achieve continuous conveying of sheet metal to stamping machine and stamping die, and stamped sheet metal workpiece can be removed from the stamping die and conveyed to the next stamping worker in a very short time. In order to realize the economic benefits of the theory, we should pay more attention to the time. Therefore, the correct stamping process should be: careful analysis and research of the whole stamping process of sheet metal parts, to ensure that the whole process from the beginning of sheet metal feeding to the completion of sheet metal parts processing, has the expected shortest production rhythm, so as to achieve the best efficiency.

Opportunity One: High Growth of Domestic Automobile Market "In the next ten years, China's demand for automobiles will remain at an average annual growth rate of 13%-15%. Compared with the world's automotive powers, China's automotive market has a relatively long period of rapid growth. This period is probably from 2009 to 2023, spanning about 15 years. This is a period for all domestic spare parts enterprises. Good opportunities for development."

Sheet metal parts are thin and easy to form. They can be formed into parts of various shapes. With the application of welding, assembling and riveting technology, it is possible to realize multi-structure of products. At the same time, these characteristics make sheet metal parts more or less deformed in the process of processing, such as bending deformation, torsion deformation, concave-convex deformation and so on. These deformations make the size or shape of the whole component change, resulting in quality problems. However, the production process of sheet metal parts has its inherent law. For the same type of products, according to the existing equipment, manpower, etc., the order of processing can be flexibly adjusted, and reasonable processing technology can be given. So choosing the right technological route is an effective measure to prevent and solve this kind of problem.

The so-called sheet metal refers to the products processed by sheet metal technology. Sheet metal has been widely used in our daily life. Sheet metal has the characteristics of light weight, high strength, conductivity (can be used for electromagnetic shielding), low cost and good mass production performance. The common problems in the use process are rust on the surface and so on. Problem.

In order to distinguish the quality of automobile sheet metal parts, we can start with packaging, weight, welding process, painting process and the degree of coincidence when loading. It is very difficult for ordinary car owners to distinguish whether the sheet metal parts are of high quality after handing in the car. They may as well distinguish them from the packaging of the products in advance. Generally, the products produced by small factories will not print the contact information and the factory address, but the products will also have steel stamps, qualifications and test labels, even if consumers use them in the future. When problems arise, there can also be a way to safeguard rights.

Spray painting of automobile sheet metal parts is an operation with professional skills. In operation, attention should be paid to the uniformity of the spray paint, the smoothness of the paint surface, and whether the color of the spray paint is consistent with the color of the car body.
