Background technique

The embryonic form of the low-pressure casting method can be traced back to the beginning of the last century. It was applied to aluminum alloy in France in 1917 and in Germany in 1924, but it did not form a large-scale industrial production. The production for commercial purposes began in 1945 after World War II. Mr. Lewis of the United Kingdom founded the Arumascu Company and began to produce rainwater pipes and beer containers. In the 1950s, cylinder heads were produced in Austria and Germany. In 1958, Zeneramotas of the United States used a large number of aluminum alloy castings on engine parts (cylinder heads, boxes, and gearboxes) of small cars, and adopted a low-pressure casting method. This event was an indispensable impetus to the low-pressure casting method that is still widely used today, and especially caused great repercussions in the automotive industry all over the world. The low-pressure casting method was introduced into my country around 1957, but it really attracted the attention of the industry, and it was around 1960 that various researches and equipment were introduced.
