Die casting belongs to permanent mold casting. At the beginning of the 19th century, due to the need of movable type typesetting, William George produced a type casting machine with a daily output of 12000 to 20000 types. In 1838, little David Bruce produced an automatic typecasting machine. In 1868, Charles Babbage developed a die-casting equipment for the production of mechanical computer parts, which made amazing achievements in die-casting production.
In 1877, duesenbury improved the pressure chamber structure so that the mold could move horizontally.
In the 1860s, Charles Babbage designed a piston type machine for injecting molten metal, and at the same time, he used a mold.
The first gooseneck die-casting machine was designed by wenschner in 1907. This machine is pneumatically operated. It has no injection plunger and uses compressed air to press molten aluminum metal into the mold through a fixed gooseneck. Its appearance started the attempt of aluminum alloy die casting.
In the 19th century, die-casting began to be used in the manufacturing of currency, camera parts and bicycle industries, and began to die-cast automotive parts. Since then, the die-casting industry has maintained a kinship with the automotive industry.
At the beginning of the 20th century, zinc alloys and aluminum alloys began to replace lead and tin alloys in the field of die casting.
In the 1920s, people tried to cast brass. Due to the need of die-casting alloys with high melting points, such as aluminum and copper, people came up with the idea of separating the furnace from the machine. Therefore, the cold chamber die casting machine appeared. Among them, a cold chamber vertical die-casting machine invented by Czech engineer Joseph Pollack is suitable for casting zinc, aluminum, copper and other alloys. Then, the United States developed the cold chamber horizontal die-casting machine, which is simple to operate. Together with the cold chamber vertical die-casting machine, it has become the standard equipment for die-casting aluminum, magnesium, copper and zinc alloys.
Since then, die casting technology has begun a period of comprehensive development and increasingly mature. In addition to pneumatic die-casting machines, there are also full hydraulic and hydraulic mechanical die-casting machines, and "vacuum die-casting" for the production of high-quality aircraft castings. Although this kind of equipment is expensive and complex to operate, it plays a key role in the production of some special parts. Although it is not widely used, it has continued to this day. In addition, there is also a "rotor die casting machine" that produces motor rotors.
