With their optimized tool steels and expertise in innovative 3D printing, voestalpine companies demonstrated their capabilities at EUROGUSS 2020, Europe’s leading trade fair for the die casting industry.
At EUROGUSS 2020 the voestalpine companies demonstrated their expertise in the field of additive manufacturing, innovative steel brands, and production experience. The turbulence caused by changes in the automotive market is having a broad impact. The die casting industry also faces major challenges with respect to lightweight construction and emissions reductions.
voestalpine innovations strengthen lightweight construction
voestalpine products support the industry’s efforts towards lightweight construction, the exhibitors from voestalpine High Performance Metals Deutschland GmbH with its BÖHLER and Uddeholm brands, Buderus Edelstahl GmbH, and Eschmann Stahl GmbH are all convinced. Stefan Wetzel of voestalpine High Performance Metals Deutschland GmbH explains: “We can meet the demand for steel brands for optimized die casting tools with our BÖHLER W350 special brands, and particularly with BÖHLER W360, which is available in round, flat, plate, or ingot form, and as an additive manufacturing powder. They make the hybrid construction of die casting inserts economic.” The manufacturers of tool mold steel within the Group are continually optimizing their product range to offer greater fatigue strength, toughness, and corrosion resistance, as well as improved workability, and weldability.
The demands made of die cast products are primarily:
- reduced wall thicknesses;
- improved surface qualities;
- more complex geometries, and
- closer tolerances.
The goal in the industry is for lightweight construction to enable the process-reliable manufacture of wall thicknesses of 2.0 mm. The material savings will result in a 1:1 reduction in vehicle weights, manufacturers claim. This is contingent upon near-net-shape tempering of tools which–because of current voestalpine capabilities–is a realizable aspiration.
voestalpine 3D printing has a sustainable impact
The tool inserts demonstrated by the voestalpine Additive Manufacturing Center Düsseldorf have already proven this.
"By printing tools using voestalpine steels, the voestalpine Additive Manufacturing Center produces tools which are sustainable in many ways. They reduce the scrap rate, increase the service life of the tool insert, and reduce CO2 emissions."
DGH Heidenau, a voestalpine customer in Dohna, Saxony, is able to reduce its annual CO2-footprint by around 80 tons, purely through the use of cooling-optimized tool inserts. The developers at voestalpine improved the temperature management by introducing near-net-shape cooling channels. The sustainable tool was built by means of additive manufacturing using BÖHLER W360 AMPO. “To date the voestalpine Center in Düsseldorf is the only manufacturer of die casting mold steels of this class,” stressed Armin Wiedenegger.
Effective partnership between Buderus Edelstahl and Eschmann Stahl
At EUROGUSS 2020 Buderus Edelstahl GmbH and Eschmann Stahl GmbH, companies in the voestalpine High Performance Metals division, demonstrated the effectiveness of their joint sales strategy. “Tool inserts and filling chambers made from EschmannStahl tool steels are the perfect supplement to Buderus Edelstahl die casting mold frames, and that was something we were able to clearly demonstrate to our guests at the joint EUROGUSS stand,” said sales executive Oliver Schaub, Buderus Edelstahl GmbH, highlighting the synergy of the joint appearance.
With over 750 exhibitors from 36 countries, the Nuremberg-based trade fair was once again a success for exhibitors. The voestalpine companies at the show agree:
