Foundry

The melting processes are performed in two arc furnaces with 4.5 tonnes capacity and two coreless-type induction furnaces with 500 kilogram capacity.
We perform the chemical analysis by a vacuum spectrometer.
The cold-bonded furan resin moulding process is made by moulding machine controlled by a micro-processor. The cores are made by a core-shouting machine operated automatically and half automatically and it uses cold-box system.
Casting of the boxless mould is performed on five cycle-controlled line . The fettling is made by a shot-blasting machine. After the dressing off and trimming all the castings are heat treated in furnaces heated by electricity or gas.
The foundry is able to produce castings made of carbon steel, low alloyed steel, heat- and corrosion resistant steel in good quality according to MSZ, EN, ASTM , BS and DIN standards and special costumer’s Standards.

Machine engineering
The applied technology is suitable for machining of the Corporation’s own steel castings.
  • Machining: by traditional and CNC controlled lathes or drilling-milling CNC machining centre.
  • Mechanic works: arc welding by sheathed electrode and welding in protective atmosphere
  • Assembling activities.

    Quality control
    The company has certifications from TÜV, L'loyd, Deutsche Bahn, SNCF, for its quality control system, menufacturing areas (pouring, machining, welding, assembly) and products.
    The company have integrated into it's since 1997 working quality control system acc. to MSZ EN ISO 9001 standard, and get approved by TÜV SÜD the IRIS Rev.2 - International Railway Industry Standard for the railway products (steel and steel casting prodictionm machining and welding).
    Certifications of the company can be see in the quality folder

    These days the foundry, which was originally established to produce high pressure armatures, produces machinery ( parts of earth-moving machines ), parts for vehicle, railway and electric power units and casting for building.
    By means of the machining background facilities we deliver rough and finish machined castings being in higher technical condition. The foreign market share of the Corporation has been increasing significantly.
    Beside of increasing the export it is very important to keep and develop our domestic markets and to reduce costs and expenses of our business.
