The shot blasting solution of Rösler will enhance Alupress’s production efficiency, while maintaining the high-quality finish required for complex components used in electric vehicles.
To meet the rising demand for electric vehicle components, Alupress GmbH expanded its shot blasting capacity with the help of Rösler, a surface finishing solutions supplier. Indeed, Alupress has invested in Rösler’s continuous feed spinner hanger blast machine, equipped with a power & free transport system. This custom-designed setup ensures effective yet gentle de-flashing of die-cast aluminum and magnesium parts, preventing deformation even in thin-walled, intricate designs.
The shift towards lightweight materials like aluminum, essential for increasing battery range in EVs, has led to a surge in demand for high-precision die-cast parts. To address this, Alupress's facilities in both Hildburghausen (Germany) and Brixen (Italy), integrated Rösler’s advanced shot blasting technology to meet strict automotive industry standards. Rösler’s tailored equipment enables Alupress to efficiently process delicate parts - highlighting Rösler’s role in supporting manufacturers as they adapt to the evolving needs of the electric vehicle market.
Automated shot blasting solution that minimises the risk of work piece warping
Alupress GmbH chose Rösler for an automated shot blasting solution designed to prevent warping in delicate aluminum and magnesium die-cast components. The key requirement was a gentle yet efficient de-flashing process due to the thin walls and intricate shapes of the parts. Rösler's RHBD 13/18-So continuous feed spinner hanger blast machine, paired with an automated power & free transport system, fulfilled these needs by integrating de-flashing, cleaning, and quality control checks into a seamless process, thus enhancing productivity.
The machine features eight high-powered turbines (11 kW each) with wide throwing blades arranged on both sides of the blast chamber. This unique duplex setup ensures an even force application, minimizing the risk of deformation while maintaining efficiency. Additionally, a rotating workpiece carrier holding up to 80 components oscillates during blasting to achieve thorough de-flashing, including in hard-to-reach areas. The use of small aluminum cut wire as media, managed with a specialized dust collector and air wash separator, ensures minimal media loss. Safety features like multiple cleaning connections and a wet dust collector compliant with ATEX standards further highlight Rösler's focus on precision and reliability, making it an ideal partner for Alupress's expanding needs in the electric vehicle industry.
The decision to partner with Rösler was driven by their proven expertise in handling sensitive work pieces and their reputation for delivering high-quality, reliable equipment. Alupress had previously worked with Rösler on similar projects and experienced the benefits of their advanced shot blasting machinery, excellent after-sales service, and overall technical competence. This long-standing relationship and consistent performance made Rösler the ideal choice for expanding Alupress’s shot blasting capabilities to meet the growing demands of the electric vehicle industry.
Ergonomic features for improved employee health
Rösler’s shot blasting solution incorporates ergonomic and safety features to enhance employee well-being and streamline operations. The power & free handling system facilitates easy transport of work pieces, with adjustable height at the loading/unloading station to accommodate operators comfortably. Generous buffer sections ensure continuous workflow even during breaks, reducing downtime. Additionally, safety mats replace traditional sensors around hazardous areas, providing a secure environment and prioritizing operator safety while maintaining efficient, uninterrupted production.
