Metal casting for gas-fired models Lost Foam Casting is improved in the shops, and we also continue to equip the foundry with equipment. Modernization of the foundry on the basis of science. For the quality of shaped castings, economy and high production culture, today there is no alternative to casting on gasified models (LGM). Foam models are often manufactured on a CNC machine or 3D milling machine.
In the sand form, a single foam model is replaced by molten metal when pouring, which gives a cast of any of the most complex geometries of ferrous and non-ferrous alloys. When forming small models are assembled into blocks or bushes and placed in the volume of the mold, and not in the plane as in the usual form. The absence of traditional shapes and rods eliminates the use of molding and core compounds, the molding consists of filling the model with sand.
For 1 ton of casting consumes only 4 types of model-molding materials: quartz sand -50 kg, expanded polystyrene - 6 kg, non-stick coating-25 kg, polyethylene film. - 10 sq.m.
In recent years, LGM technology is increasingly used in foundries. The world practice shows a constant increase in the production of castings by this method, which exceeded 1.5 million tons per year, is especially popular in the USA and China (in one PRC more than 200 such shops have been working since 2006, producing up to 2 million tons of castings in year). The developer and supplier of casting equipment for foam plastic models is the FTIMS Institute (Kiev), which supplied the equipment and launched a number of LGM sites.
In the foundry of Russia and Ukraine, more and more such workshops are being created. Equipment for LGM, which is supplied by FTIMS inexpensive and easy to use when casting ferrous and non-ferrous metals with a casting weight of 0.1-1250 kg. Foundry shop FTIMS (Kiev) pilot production produces such castings of cast iron, steel, aluminum, copper alloys up to 50 tons per month, serial and single parts, designs and manufactures molds for models. Foundry - the master casting castings of cast iron, steel, aluminum, copper alloys, serial and single parts.
