History of aluminum alloy die casting

There are different views on the development history of die casting. According to the records of related articles, die-casting lead first appeared. 1822, William Qiao Qi built a movable type casting machine with a daily output of1.2 ~ 20,000. Twenty years later, J.J.Sturgiss designed and manufactured the first manual piston hot chamber die casting machine, and obtained a patent in the United States. 1885, Morgan Tulle studied the previous patents and invented the printing die casting machine. By 65438+60s, it was used to produce zinc alloy die castings. Die casting was widely used in industrial production at the beginning of last century. During the period of 1905, H.H.Doehler successfully developed die casting machines and zinc, tin and copper alloy castings for industrial production. Subsequently, Wagner designed a gooseneck pneumatic die casting machine to produce aluminum alloy die castings.
