Zinc alloy castings have the advantages of easy forming and high processing accuracy. In recent years, with the emergence of peoples demand for lighting, hardware products and home appliances products, as well as the appearance and artistic modeling

There are many types of stamping dies, and the dies are also classified according to the three aspects of working properties, mold structure and mold materials. Generally can be classified according to the following main characteristics: 1. Classific

Compared with castings and forgings, stamping parts are thin, uniform, light and strong. Stamping can make the workpiece with rib, undulation or flanging which is difficult to be made by other methods, so as to improve its rigidity. Due to the use of precision die, the precision of workpiece can reach micron level, and the repetition precision is high, the specification is consistent, and the hole and socket, boss, etc. can be punched. Generally, cold stamping parts are no longer machined, or only need a small amount of machining. The accuracy and surface state of hot stamping parts are lower than that of cold stamping parts, but they are still better than castings and forgings, and the machining amount is less.

Gravity casting is a relatively common casting method in the modern metal component manufacturing industry. It mainly uses metal melt to inject into the finished product mold, fills it with gravity, and finally cools to complete the molding process. This casting method has a wide range of applications in the production and processing of metal parts.

60-70% of the world's steel is plate, most of which are made into finished products by stamping. Automobile body, chassis, oil tank, radiator plate, boiler drum, container shell, motor, electrical core silicon steel plate are all stamping processing. There are also a large number of stamping parts in instruments, household appliances, bicycles, office machinery, household utensils and other products.

Stamping part is a kind of production technology which can directly deform the sheet metal in the die with the help of the power of conventional or special stamping equipment, so as to obtain certain shape, size and performance of product parts. Sheet metal, die and equipment are the three elements of stamping. Stamping is a method of metal cold deformation. Therefore, it is called cold stamping or sheet metal stamping, or stamping for short.

As the basis of the automobile industry, auto parts are necessary factors to support the sustainable and healthy development of the automobile industry. In particular, the current auto industry is developing vigorously and in full swing for independent development and innovation, and it needs a strong component system to support it. Vehicle independent brands and technological innovation need parts as a basis, and independent innovation of components has a strong driving force for the development of the vehicle industry. They interact and interact with each other. There is no independent brand of the vehicle and a strong parts system. Its R & D and innovation capabilities are difficult to develop without the support of a strong parts system.

In the process of gravity casting, it mainly refers to the process of effectively injecting metal liquid into its mold under the action of gravity. It is also known as casting. Gravity casting effectively includes investment casting and sand casting in a broad sense. , Clay mold casting, metal mold casting, etc

Regarding gravity casting, through the previous study, we can know that it is a process of casting by gravity, referred to as gravity casting, or gravity casting, and the finished product we obtained is called casting. Then, for the study of gravity casting, the following will continue through two aspects

Zinc die casting process is everywhere. It is commonly used for parts manufacturing in industrial and construction industry, as well as in automotive industry. Many components of automobiles can be made by zinc die casting. It can be said that modern process originated from the automotive industry.

The process of aluminum alloy die casting is highly popular for making parts in building and industrial fields, but its most common application is in automotive industry. Compared with other manufacturing processes, the die casting process has the advantages of high production efficiency, high dimensional accuracy, excellent mechanical properties, high material utilization rate and better economic benefits of mass production. In the automotive aluminum alloy parts, die-casting aluminum alloy and other casting aluminum alloy components account for about 80%, processing aluminum only accounts for about 20%, and the consumption of die casting parts accounts for about 70% of the total amount of casting products. Therefore, die casting aluminum alloy products account for 54% – 70% of the automotive aluminum. With the increasing production of aluminum alloy die casting, aluminum die casting is gradually applied to automobile parts industry.

The following is a data analysis report of China’s aluminum die-casting industry for 2020-2022, which introduces in detail the market competition situation of aluminum die casting manufacturing industry, the independent innovation and development trend of aluminum die casting technology.
