As a Die Casting Parts Supplier, share with you. Hot chamber die casting Hot chamber die casting, sometimes called gooseneck die casting, is a molten, liquid, semi-liquid metal in a metal pool that fills the mold under pressure. At the beginning of the cycle, the piston of the machine is in a contracted state, at which time the molten metal will fill the gooseneck. A pneumatic or hydraulic piston squeezes the metal and fills it into the mold. The advantages of this system include rapid cycling (approximately 15 cycles per minute), ease of automation, and the ability to melt metals. Disadvantages include the inability to die-cast metals with higher melting points, and die-casting of aluminum because aluminum will carry iron out of the molten pool. Therefore, hot chamber die casting machines are commonly used for zinc, tin and lead alloys.

The four basic processes of die casting aluminum industry are annealing, normalizing, quenching and tempering. These four processes are called “four fires” in die casting. In the process of die casting, the relationship between quenching and tempering is very close, and one of them is indispensable.

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.

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.

The spread of COVID-19 has a great impact on human life and production, as an important part of the manufacturing industry, the die casting industry can’t be spared. What challenges and difficulties will the epidemic situation have on the casting foundry and die casting automobile parts supply? What measures should a die casting company take to turn the crisis into an opportunity?

Die casting is a process employing the pressure to inject molten metal into a mold or die, then to obtain the casting products that have exact shapes or geometries as the internal shape of the mould. In this article, we’ll talk about the equipment for this process, what is die casting machine and common types of die casting machines, as well as their mechanism and selection.
