EUROGUSS 2020 News Optimized Processing of High-Pressure Die Cast Parts
Higher quality and efficiency in post-processing of high-pressure die casting components, Friction Stir Welding for aluminum components for electro mobility combined with a high automation competency: at Euroguss 2020, Grenzebach presents its portfolio.
Friction Stir Welding for E-mobility
During the Auto Summit in Berlin early November, politicians, association representatives and industry members once more emphasized their commitment to electro mobility. New mobility concepts, such as traveling with “green” electric power, have a direct impact on the development of casting components. “We observe an increased demand for welding of die cast components in the automotive industry, such as the manufacturing of battery trays or heat exchangers for electric vehicles. This is where our Friction Stir Welding solution can make a difference”, says Sahin Sünger, Product Manager for Friction Stir Welding at Grenzebach. Commonly, this involves work with cavity-prone die cast parts with uneven surfaces, which is extremely difficult to do with conventional welding technologies. This is where Friction Stir Welding makes the difference. A rotating tool generates the required process heat at the seam with friction and pressure. The material becomes plastically deformable with the heat applied and is stirred along the joint with the rotation of the tool.
Scalable Solutions Focused on Efficiency
The FSW technology enables the production of durable and media-tight weldings. Since Friction Stir Welding is a solid state joining technology no pores or hot cracks are generated. Exactly these effects are very common to conventional fusion welding. Grenzebach offers scalable FSW solutions for serial production. The double spindle FSW gantry units of the D-DSM series provide two independently working welding heads. “With this innovation, our customers can reduce their effective cycle time. Besides the dynamics and the welding speed, the quick loading and unloading of the machine are critical for cycle time and economic efficiency. Our customers can benefit from our expertise of numerous successful projects”, says Sahin Sünger.
Aluminum Still on the Rise
The FSW technology more and more complements the foundry technology, also due to the fact that aluminum substitutes steel! The automotive and aviation sector count on lightweight components; in mechanical engineering, aluminum ideally withstands mechanical stresses. “The quantity of processed aluminum in vehicle bodies increases every year. Especially in the automotive industry changes are under way. That is why support our customers with the use of FSW technology and the development of new products offering consulting services and sample weldings”, says Sünger.
