The United States is one of the first countries to use the lost foam casting method in foreign countries. MIT college began to study the lost foam casting method in 1959. Alfred Duca successfully poured works of Art – Bronze Pegasus and ductile iron bell frames by using the foam evaporation method developed by himself.
In 1974, Ford Motors produced aluminum alloy castings by lost foam casting method. In 1982, G motors. Of the United States established a fully automated lost foam aluminum alloy casting production line for producing aluminum alloy cylinder heads and intake and exhaust manifolds; Ford Motors established the first automatic full mold casting production line in 1984, with a production efficiency of 180 models per hour. The annual output of intake manifold produced by this production line can reach more than 3 million pieces. About 5% of the castings failed to meet the production requirements due to the damage of the pattern in the molding process. In 1987, Saturn company of the United States established a lost foam casting production line of 80 cases / h for the production of auto parts. The production line of the company is the equipment imported from Vulcan company and fata company of the United States.
In 1984, Robinson’s automatic gray iron production line with an output of 50t / h was built in its gray iron foundry. In addition, many enterprises of out board marinecorp and John Deere also began to raise a lot of funds to set up lost foam casting production line or foundry, and use this method to produce the required workpieces.
The picture shows the development of production output and types of lost foam castings in the United States from the end of the 20th century.
