Current status of China’s die-casting industry


The economic environment promotes steady growth in industry scale

Die casting, also known as "pressure casting", refers to a method in which liquid or semi-liquid metal fills the die-casting mold cavity at a high speed under high pressure, and then forms and solidifies under pressure to obtain castings.

Die casting is a metal casting process characterized by applying high pressure to molten metal using a mold cavity. Molds are typically machined from stronger alloys, a process somewhat similar to injection molding. Most die-cast castings are iron-free, such as zinc, copper, aluminum, magnesium, lead, tin and lead-tin alloys and their alloys. Depending on the type of die casting, a cold chamber die casting machine or a hot chamber die casting machine is required. Divided according to the material of die-casting products, the main product categories of the die-casting industry include: aluminum alloy die-casting products, zinc alloy die-casting products, copper alloy die-casting products, magnesium alloy die-casting molds, and other metal die-casting molds.

my country's die-casting industry has gone through four stages of development, from the embryonic period in the 1850s to the current period of rapid growth in the 21st century. Thanks to the rapid development of the national economy, in the context of the rapid growth of my country's automobile industry, the production and sales of automobile die-casting parts have The volume increased significantly and reached a certain scale.

From the perspective of development history, my country's die-casting industry has also formed an industry with Chinese characteristics. Currently, our country has more than 3,000 non-ferrous metal die-casting production companies with tens of thousands of die-casting production employees. Entering the 21st century, with the rapid development of the national economy and driven by the downstream automobile, communication equipment manufacturing, railway locomotive and general equipment manufacturing industries, the die-casting industry has developed rapidly. Die-casting companies have begun to concentrate in South China and East China, forming a certain Due to technological advancement, the types and complexity of die-casting products are also increasing in the industrial clusters formed around leading downstream companies. At the same time, due to my country's labor cost advantages, foreign die-casting manufacturers have also begun to gradually transfer their industries to my country.

China's die-casting industry will develop professionally in the future

Since the emergence of the die-casting industry to its large-scale development in my country today, the industry has continued to improve and will evolve and develop in a better direction in the future. The development direction will be mainly reflected in four aspects: In order to be more consistent with other downstream industries, products will gradually become centralized. and regionalization; in order to meet higher technology requirements, products will also be more high-end; in order to better meet customer needs, companies will participate in customer R&D systems and carry out targeted development; in order to adapt to the rapid development needs of the industry, companies will Strive to achieve modular production.
