This technological upgrade also has a significant impact on operational sustainability. RKL Slévárna is actively and demonstrably reducing its environmental footprint.

The entire installation of the S-Max® printer was a challenging project carried out with the support of our partners. Our sister company, RKL Opava, handled the transportation of the equipment, and experts from Colmex Sp. z o.o., the distributor, as well as experts directly from the manufacturer, ExOne, assisted with the commissioning.

The entire holding company team, the management of our partner company Storvik, representatives of our technology partner ExOne, and the distributor Colmex attended the ceremonial launch of full-scale operations. The symbolic ribbon marking the start of production was ceremonially cut by the holding company’s owner, Mr. Karel Suchánek, and a representative of Storvik, Mr. Nils L. Sande.
