Die Casting
- Hans-Günter Krull (Deutsche Edelstahlwerke Witten Krefeld GmbH)
Highly stressed aluminum components, such as wheels and chassis parts, are often manufactured using low-pressure die casting. This is partly because the process results in a particularly low-oxide and low-porosity microstructure and therefore high strength and elongation at break. However, the increasing complexity of components and the desire to save weight also leads to challenges in...
Aluminum die casting plays a major role in automotive construction and is becoming even more important due to new production technologies such as giga-casting. In the interests of climate-friendly production, however, the CO2 footprint across the entire process chain must also be increasingly considered and approaches must be sought to minimize CO2 emissions. Toolmaking must not be left out of...
Copper alloy components, such as molds and tooling, allow efficient thermal dissipation but are prone to surface damage due to their relatively low strength. Applying hard coatings such as tool steels deposited by laser cladding, can significantly enhance surface strength, thereby extending the lifespan of these components.
In this study, H13 coatings with varying thicknesses were deposited...
The integrated die-casting technology significantly enhances the production efficiency of new energy vehicles while reducing costs, leading a revolution in the new energy vehicle industry. This technology places higher demands on the die steel materials used, and the availability of large-sized die steel is one of the bottlenecks encountered in the industrialization and application of this...
