| The plant produces aluminium high-precision castings for
enterprises of automobile and machine building industries, parts for electric
motors, household appliances and others.
Method of metals injection moulding ensures a high-precision
dimensions (the 3-d – 7-th grades of accuracy), relief purity and roughness of surface (for aluminium castings – the
5-th – 8-th grades of accuracy), that all minimizes further machining.
Industrial and food aluminium melting of АК7П, АК12, АК5М2 grades is carried out in ЭСТ-250 electric furnaces with 250-kg crucibles.
At the plant for injection moulding versatile
casting machines (711А07 and 711А08 models) are used.
