Cast-iron production is a closed technological cycle of mass production of grey cast-iron, ductile cast-iron castings as well as alloyed cast-iron castings of various grades. The melting of cast-iron is carried out in coreless induction and arc furnaces made in Russia and in Germany. Mixers of different capacities are used to warm up and soak the metal.
Automatic molding lines for flaskless molding manufactured by DISAMATIC (Denmark) is capable by using cores to produce castings of any complexity weighing from 0,2 to 20 kg. Up-to-date high-productive automatic moulding line DISA 230A (Denmark) allows not only to provide high degree of accuracy of the produced castings but also considerably reduce production cycle and the opportunity to put in minimum machining allowances in the casting reduces time and expences for manufacture of the machined part.
Large size castings (0,1 - 20 tons) such as bulky dies, various architectural modules (barriers, lamp posts, benches, etc.) and other castings weighing from 0,1 to 20 tons are produced in flasks, caissons and in casting pits with the use of hand moulding technique. To create diverse cavities in the castings Japanese (NANIVA) and domestic-made core-making machines are used.
The production capacity of cast iron castings is 35 000 tons annually.
The main types of castings that we produce are:
-anchor and rail joints for railway;
-sewage and sidewalk grids;
-impellers for water pumps;
-truck and tractor cylinder liners and other various parts (more than 300 items).
