Hub for railway technology in

southeast Europe

DIHAG’s Euro Metall iron foundry in the Hungarian capital Budapest, produces brake parts for railways.

Together with a German and a Polish foundry the company thus covers Europe’s markets

The molding boxes are slowly moving

forwards in the AFA 20 molding

plant. One after another, two casters

approach the casting line, each pulling

a 350 kg ladle filled with glowing

molten metal suspended from a hall

crane. Then casting takes place: there’s

a hiss, and the molten metal rapidly

disappears into the inlet, almost unrecognizable

in black bentonite molding

sand. After a short time, smoke rises

from between the two molding box

halves, flames flicker. The men concentrate

on holding the ladles in position

for a minute or two. Beads of

sweat form on their foreheads above

the dark protective goggles.

Proven technology on historic

ground

Some of the foundry machinery used

stems from the former East Germany

and continues to do its duty reliably

here in the suburb of Újpest in the

north of the Hungarian capital: the

flasked molding plant with a capacity

of 93 - 110 boxes per hour and the

sand regeneration plant. The recycled

used sand is mixed with bentonite after

each cycle and then renews its journey

– through the vibrating presses

to the cope and drag boxes, along the

core insert and casting lines until being

shaken out. The plants are logically

installed one after the other in an area

measuring about 50 x 20 square meters.

Many hundred thousand tonnes

of castings must have been cast here

during the foundry’s 111-year history.

one goes on the works grounds: a

wing, a locomotive with a red star on the

front shows visitors the way to the production

building and, next to the foundry

on the repair grounds of the Hungarian

state railway, old steam engines of all

ages stand in ramshackle halls – a paradise

for railway enthusiasts. The timeless

atmosphere in the casting hall fits

in well here: vibration presses rattle, the

smell of amines lies in the air, and casters

do their work in long aprons and protective

clothing – weathered writing in

large letters on the wall call for order and

safety. On the wall next to the pair of cupola

furnaces only the calendar provided

by the Austrian binding agent and

facing experts Furtenbach (on which a

pin-up girl displays her assets to full advantage)

provides a reference to the present

by displaying the year 2014.

MÁV is largest single customer

László Retter has been Managing Director

here for two years. His foundry,

called Euro Metall Kft., has been a member

of the Essen-based DIHAG group of

foundries since 2002. The works currently

produces 13,500 tonnes of castings

per year, which corresponds to adjusted

sales of 10.9 million Euros. The

factory is thus working at about 80 % capacity

utilization. The foundry produces

brake technology – brake blocks, weight

castings and ribbed plates – and, with

this product portfolio, is the group’s

southeast Europe hub for the markets

in Hungary, Romania, Slovenia, Serbia,

Croatia, Slovakia and the Czech Republic.

Some of its production, however,

is also exported to Austria, the UK and

Germany, as well as to some other west-
