On the basis of advanced technology around the world, this Lost foam casting equipment which is combined with China's national conditions and practice meets the technological requirements. Meanwhile there are many outstanding features such as small investment, quick effectiveness, labor saving, stable performance, flexible production, wide range of applications, etc. Lost foam casting equipment is ideal for new and old commercial foundry to reform technique.
According to the process, this method makes foam plastic pattern (manual, mechanical) first, and then smear some special coating. After drying, place in a special sand-box and fill in dry sand. Three-dimensional vibration is tough. When casting begins in vacuum condition, model gasification disappears. Liquid metal will replace the pattern and duplicated castings as the foam plastic pattern come into beings.
Process flow:
4, Release the vacuum; Turn over the box after the casting is condensed; Take the casting out of the loose dry sand. Proceed to the next cycle.
Technical advantages:
EPC process sets full mold casting, advantages of v-process casting process as a whole. Lost foam casting equipment is suitable for cast steel, cast iron, bronze, cast aluminum and other brands, as well as all kinds of material, different structures and size( large, medium and small ) of all kinds of castings. The type is fixed by dry sand, and the prototype is original. The casting is highly precise, uniform and no less than core, and not to box, and the casting is not Burr. The smooth of the surface is close to precise casting. Its internal structural is stable, which remove and reduce the defects such as blowholes and gas air. There are two level of environmental treatment throughout the production process, so as to get rid of pollution.
To sum up, the EPC in line with overall trends in today's casting technology development, as well as bright prospects. Compared with traditional casting technologies, EPC technologies has unparalleled advantages. In 1999, the National Ministry of science and technology focused on the promotion of EPC technology in national high-tech. It is foundry industry at home and abroad as the "casting technology of the 21st century", "casting industry of green revolution".
