History of development
The history of the development of die-casting is quite different. According to the relevant article, the first thing that happe** was die-casting lead. In 1822, Willam Church created a lead type **hine with a daily output of 1.2 to 20,000 letters. Twenty years later, J.J. Sturgiss desig** and created the first manual piston hot chamber die casting **hine and obtai** a patent in the **. In 1885, Mørgenzel studied previous patents and invented a press die casting **hine. By the 1860s for the production of zinc alloy die-cast parts. Die-casting is widely used in industrial production only at the beginning of the last century. In 1905, H.H. Doehler successfully developed die casting **hines, die-cast zinc, tin and copper alloy castings for industrial production. Wagner then desig** a gooseneck pneumatic die casting **hine for the production of aluminum alloy die castings.
