The first China die casting equipment was invented in 1838 as a small manual machine, patented in 1849. The combination of tin and lead is melted and then poured into steel molds - this mold is called "mold". As a metal alloy is cooled, a mold is formed and cured. The last element taken from the mold is "casting".
Over the past 30 years, China die casting is only used to help the printer create type. From the beginning of the 1890s, more molds were created in various shapes. As the world enters the new century, cash registers, phonographs, frames and other large-scale production elements are being created by die casting.
The new mold allows die-casting in almost every major industry to provide spare parts for the machinery supplied to the country.
Lead and tin are the main metals used in early die casting, and they have significant ductility. From 1914 onwards, when the introduction of zinc and aluminum alloy, the process transferred to a more secure material, but also can make the product more powerful.
Copper and magnesium alloys are introduced in the coming years, and most of today's alloys are available in the mid-1930s. Now the expansion of the material makes the die casting machine to create a wide range of components and products for flexibility, heat resistance, erosion or weatherability, reuse and so on.
With the introduction of new alloys, the die-casting process has changed to accommodate new requirements and the creation of new parts. Early, die-casting machinery can only produce low-pressure injection system, to consistently produce high-quality products. Since the strength and heat resistance of the materials used to develop the machine are improved, a higher pressure condition and process are allowed later.
Today, high pressure casting methods have become standard, usually offering better quality products and strong finished products. Found in today's mechanical equipment is very strong parts, with excellent surface finish, and delivery is very large. There are new alloys than ever better performance, opened up a new die-casting market.
