Introduction
Die casting is a kind of precision casting method that uses high pressure to force the metal to be hydraulically poured into a complex metal mold. In 1964, the Japan Die Casting Association defined die casting as "a method of casting a molten alloy into a precision mold at a high temperature and producing a high-precision and excellent casting surface in a short time." In the United States, die casting is called Die Casting, while in the UK, die casting is called Pressure Die Casting, and the most common in the domestic industry is the Japanese saying, called die casting. Castings produced by die casting are called Die castings.
The tensile strength of these materials is nearly twice as high as that of ordinary cast alloys. It is more positive for aluminum alloy automobile wheels, frames and other parts that are expected to be produced with higher strength and impact resistant materials.
history
In 1838, in order to manufacture molds for movable type printing, people invented die casting equipment. The first patent related to die casting was enacted in 1849 as a small manual machine for the production of press type letters. In 1885, Otto Mergenthaler invented the Linotype typewriter, which was able to die-cast a whole line of text into a single typeface, bringing unprecedented innovation to the printing industry. After the printing industry entered large-scale industrialization, the traditional hand-pressed fonts have been replaced by die-casting. Around 1900, the casting typesetting entered the market, which further improved the printing industry automation technology. Therefore, sometimes more than ten die casting machines can be seen in the newspaper. With the continuous growth of consumer products, Otto's invention has gained more and more applications. People can use the die-casting to manufacture parts and components in large quantities. In 1966, General Dynamics invented the precision die casting process, which is sometimes referred to as double punch die casting [1].
