The Developing Process of Die Casting

Die castings have advantages of complex shapes, stable dimensional accuracy, simplified assembly and a variety of surface processing options. Die casting has quickly spread to other fields and has made our lives easier ever since. Do you know the history of die casting?

In 1849, Stuarts(J.J.Sturgiss) designed and manufactured the first manual piston hot chamber die casting machine, and it had been patented in the United States.

In 1885, Mersen-thaler studied the previous patent and invented a printing die casting machine, which was only used for the production of low-melting lead and tin alloy type castings and was used for manufacturing zinc alloy die casting parts in the 1860s. Die casting was widely used in industrial production only in the beginning of the last century, and was mainly applied to the production of cash registers, phonographs and bicycles.

In 1904, Franklin(H.H. Franklin) began to use die casting method to produce connecting rod bearings for cars, setting a precedent for die casting parts being used for automotive industry in UK.

In 1905, Dole (H.H.Doehler) developed a die casting machine for manufacturing zinc, tin and copper alloy die casts in industrial production. Later, Wagner designed a gooseneck type pressure die casting machine for producing aluminum alloy die castings.

In 1927, a Czech engineer, Jessf Pfolak(Jesef Pfolak), designed a cold chamber die casting machine. Crucibles that were used for storing molten alloys were separated from injection chambers, which can significantly improve injection pressure and overcome the shortcomings of hot-pressing chamber die casting machine so as to meet industrial requirements and make die casting technique move a big step. Aluminum, magnesium, copper and other alloys can be used for making die casting parts. The entire die casting process is completed in the die casting machine, and with the requirements of die casting qualities, yields and expanding applications, we have new and higher requirements for die casting facilities. Moreover, the emergence of new die casting machine and adoption of new techniques have accelerated the development of die casting manufacture.
