Compared with the United States, the lost foam casting technology in other countries developed late, but the development speed is also very fast.
Since the beginning of 1980s, Saat has designed and manufactured several production lines for the Italian foundry company fat. Among them, the more representative ones are the lost foam casting production line provided for alutek aluminum foundry in 1983 and the full-automatic lost foam casting production line provided for castek iron foundry in Turin in 1991. The former integrates casting processing and is used to produce intake manifold with production efficiency of 200 type / hour; The latter was mainly used to produce nodular iron and gray iron castings. It was not only highly automated, but also the largest lost foam casting workshop in Europe at that time. It produced 60 boxes per hour and an annual output of 5000 tons.
In 1995, a lost foam casting production line of aluminum alloy six cylinder head with an annual output of 200000 pieces was completed and put into operation in BMW automobile company of Germany. There are more than 10 production workers in the workshop. 1500 cylinder heads can be cast every day. All of them have been rough machined and tested by X-ray. The scrap rate is less than 10%.
In 1981, French Peugeot company built an advanced lost foam casting production line using CAD technology. The production line is mainly used to produce castings such as six cylinder diesel engine cylinder block, six cylinder diesel engine cylinder head and exhaust pipe, with a production efficiency of 60 cases / hour. In the same year, safam purchased a lost foam casting production line producing 40 cases per hour from utard company in France to produce iron castings and aluminum castings, with a production capacity of 7000 pieces / year.
After the Second World War, Japan’s lost foam casting technology gradually developed on the basis of drawing lessons from the introduction of new technologies from Europe and America. In the development process of lost foam casting technology in Japan, the successful experience of Ford company is absorbed, starting with the pipe fittings that are widely used, widely used and can greatly reduce the cost. After success, they are gradually promoted to other products.
Since the 1960s, Japan began to use the lost foam casting method to produce large castings. So far, Kobe iron making Institute, which has a large-scale plastic mold processing workshop and special program-controlled universal processing equipment, still uses this method to produce large machine tool castings. It was not until 1984 that Japan began to use the lost foam casting process to produce castings in large quantities. Although it started late, it has developed rapidly. Nearly 100 research institutes, companies and universities have participated in the research of EPC technology. By 1989, the total volume of lost foam casting products in Japan had leapt to the forefront of the world. At that time, the monthly output of lost foam casting of Morikawa company could reach 800 tons. However, since the late 1990s, the development of lost foam casting technology in Japan has gradually become slow. The following 10 years are even called the blank 10 years of lost foam casting technology. It was not until the early 21st century that Japan’s lost foam casting technology entered an active period.
