Development of lost foam casting in China

China is a country that began to research and apply lost foam casting after the United States, Germany, Britain and Japan.

In 1965, the Shanghai Machinery Manufacturing Technology Research Institute and the first Department of mechanical industry began to study the technology of lost foam casting. The foam materials used in the early research were mainly made of foam plastic profiles, machined and machined by electric hot wire cutting, and then processed into adhesive parts. In 1966, after one year’s experiment, Shanghai Institute of mechanical manufacturing technology obtained the preliminary success of the process test, and successfully poured the first large steel casting in China. A small climax was formed in the early 1970s. More than 50 tons of steel castings and more than 30 tons of iron castings were successfully poured in Shanghai in 1967 and 1971 respectively, which laid a solid foundation for the development and application of lost foam casting Technology in China. In 1985, China’s first lost foam casting production line was built in Changchun Institute of Optics and machinery, Chinese Academy of Sciences.

However, it was not until the middle and late 1990s that lost foam casting technology really attracted the attention of the domestic casting industry and achieved gratifying development. It has become the most widely used high-tech in transforming the traditional casting industry.

In 1993, the light engine plant of the first automobile group company introduced vibration table, pre foaming machine and forming machine from Fukang company of the United States to produce automobile aluminum alloy intake pipe.

In 1995, Quanjiao diesel engine factory introduced the lost foam casting production line for the production of four cylinder head of gray iron diesel engine from Fukang company of the United States.

In 1996, sofa motor factory, Chifeng Fulong group and Heli Forklift Group introduced lost foam casting production lines from Italy, Japan and the United States respectively for the production of aluminum alloy, gray iron and nodular iron castings.

In 2007, China became a real large country of EPC production, and the total output of EPC jumped to the first in the world, reaching 648000 tons.
