History of die casting

1838, in order to make molds for movable type printing, people invented die-casting equipment. The first patent related to die casting was issued by 1849. It is a small manual machine, which is used to produce type on the printing press. 1885, Otto Mergenthaler invented Linotype typesetting machine, which can die-cast a whole line of characters into a single font, bringing unprecedented innovation to the printing industry. After the printing industry entered large-scale industrialization, the traditional hand-pressed mold has been replaced by die casting. 1900 or so, printing entered the market, further improving the automation technology of printing industry, so sometimes more than a dozen die casting machines can be seen in newspapers. With the continuous growth of consumer products, Otto's inventions have gained more and more applications. People can mass-produce parts by die casting. 1966, General Dynamics Company invented the precision speed-intensive die-casting process, sometimes called double-punch die-casting.
