Foundry production

OZMM casting production is a large modern casting shop with annual production capacity of 35 000 tons of shaped castings. The shop is equipped with crane equipment, hoisting capacity of which reaches 80 tons.

Small-scale production is prevalent in the casting shop. The products are mainly manufactured in small lots.  But there is a possibility to produce constant serial nomenclature.

The casting shop consists of steel-smelting and molding sections.

1. Steel-smelting section is equipped with 5 electric arc furnaces with capacity of 6 and 14 tons of liquid steel. Casting ladles with capacity of 14 tons of liquid steel are equipped with locking mechanisms.
2. Molding section has two lines of the mechanized molding, the section of hand-molding and core molding. The lines of  mechanized molding are designed for:
   • large half-molds: (clear dimensions)
     2780*2600*300-900 (400; 600) mm 
     half-mold's weight is up to 15 tons
   • small and middle half-molds in boxes:
     1200*1600*500/600
     1600*2000*600 mm 
     half-mold's weight is up to 5 tons
   • hand-molded castings in boxes:
     2000*2000*500 mm
     3000*3000*500 mm
     3600*3600*600 mm

Casting production at the plant is carried out according to the latest technological processes developed  by "Borden" (UK). These technologies are based on the use of cold solidification sand blend:  Alfa-set process for mouldings and Beta-set process for cores.

 The mouldings and cores  have  tensile strength not less than 10-12 kg/cm²  and high dimensional accuracy. In heat resistance and erosion resistance they exceed traditionally applied thereto sands with furan resin. Low sands gas generation enlarges the possibility of producing responsible castings from carbon and alloyed steel grades (pump housing, valving etc.)

This technology provides the possibility of wide nomenclature production, fast readjustment  of technological process  while entering new nomenclature, reduction of pre-production time and producing of single and small-lot castings.

High strength and  short solidification cycle according to  Alfa-set process  enables  to realize snap flask molding, reducing the cost of production tooling.

Application of  "Beta-set" core manufacture  gives considerable  possibilities of highly efficient producing of complicated castings. The cores are made on core shooter  with a  cycle of  40-50 seconds.

New technological  processes of cores and mouldings production in combination  with highly-effective antiburning tools provide a  real possibility to produce castings of various degrees of complexity with minimum machining tolerances.

Using our custings  consumers will be pleased with both excellent appearance and high quality of products.
