Production possibilities of grey iron foundry

We have at our disposal for the successful excecution of the deliveries complete sand conditioning plant equiped by the peak technology of company WEBAC - Germany, having the capacity of 50 tons of bentonite sand mixture per 1 hour.

We are using the duplex system of melting to ensure high inside quality of the produced castings. Hot-blast cupola GHW - Germany without lining, with capacity of 8 - 12 tons of the molten metal per hour is the basic melting unit. The molten metal is transported to the electricity holding furnace JUNKER - Germany having capacity up to 53 tons of the molten metal. The temperature and chemical composition of the metal is homogenized there before the actual casting. The horizontal casting line BMD -Germany with the pulse box moulding into the frames 1 000 x 700 x 220/220 mms is the basic processing equipment. The capacity of this casting line verified by longterm operation is 520 - 550 frames per shift. The equipment is in permanent two-shifts operation with the regular continous preventive fettling and maintenance followed by the regular extensive revision and repairs (if necessary) every year.
 
The cleaning shop is equiped by two throughshot- blasting barrels produced by ŠKODA Ostrov - CZ , with the possibility of separate fettling or finishing on the belt blasting machine. The steel grits for blasting are used, followed by hand treatment and finishing, if necessary.

Even if more then 95 % of the castings are produced on the casting line BMD, the foundry keeps still also the hand production. The main reason is the solicitude to satisfy also small clients who need only several castings. To produce model devices for machine-moulding for such small orders will be unbearably expensive.

To ensure maximum flexibility, the molten metal for hand production can be prepared in two induction mid-frequency melting furnaces which we have at our disposal as well.
By this way the absolute independence of the hand production on grey iron prepared for casting line BMD is achieved.

The hand-producing working place is also indispensable for the trial production of some  challenging castings. We can fully make the best
of a craftsmanship and art of our moulders and founders.
