Lenaal Andrzej Pokusa is an aluminum and zinc diecaster at Radom, in central Poland, and like automotive suppliers everywhere it seeks technology and process advantages to enhance its market position. Lately, it is saving costs and improving its processes with a new tilting melting and holding furnace operation.
In addition to automotive customers, Lenaal supplies castings for engineering, electronics, household equipment, construction, and military applications.
The StrikoMelter MH II system was developed in Germany by StrikoWestofen, and assembled at its factory in Strzelce Opolskie, Poland. The furnace replaces two crucible melters that, at 120 m3 of gas per metric ton of molten aluminum, consumed nearly twice as much gas as the StrikoMelter. Thanks to its low gas consumption, the managers at Lenaal expect the investment to be repaid after about two years of operation.
Further savings result from the considerably improved material efficiency (up to 99.7%) and considerably shorter downtime resulting from longer intervals between maintenance.
In daily operation, the system does not only produce melt of excellent quality – it is also extremely economical:
