Specialty Steels for the Future of the Automotive Industry

The trend in the automotive industry is increasingly moving toward lighter, safer, and more resource-efficient vehicles. This applies not only to vehicles with low-CO2 drives but also to the production of components for electric vehicles, which rely on lighter materials to maximize range and energy efficiency. The Swiss Steel Group offers special steels such as Bainidur 1300, which enable the production of components with less material usage while optimizing performance. The bainitic steel allows cost-effective manufacturing of lightweight components that can be processed without additional tempering processes or the risk of distortion—even for large components (> 60 mm round / approx. 2.4 inches round). Due to reduced material usage and easier machinability, this steel significantly contributes to resource conservation. The Swiss Steel Group also provides tailored solutions for the most demanding applications in the automotive industry. For example, the heat-resistant steel Thermodur 2383 Supercool ensures shorter production times in the manufacturing of sheet metal components such as B-pillars by significantly reducing process costs through combined hot forming and heat treatment. The plastic mold steel SF-2000 LQ40 from Sorel Forge is characterized by a purity that enables a high-gloss polishable surface—ideal for the production of crystal-clear headlamp lenses.The special steel HSX 90 from Steeltec is used in the production of airbag casings, ensuring fast and reliable manufacturing where the steel withstands extreme stresses until the airbag is deployed.

Tooling Materials for Aircraft Interiors

Rampf develops and manufactures customized high-tech composite components for aircraft interiors—including structural and non-structural seats, seat pack boards, wall and ceiling panels, overhead bins, furniture for business jets, structural components, airflow systems, and elements for lavatory areas. Rampf offers a comprehensive portfolio of modeling and mold-making materials that maximize precision, productivity, and cost efficiency in composite manufacturing: With Raku Tool board materials, Rampf provides epoxy boards with high strength, excellent dimensional stability, and ultra-fine surfaces for fast machining and minimal rework. Close Contour Castings are near-net-shape polyurethane castings without adhesive joints, reducing milling times and material waste. The homogeneous structure ensures fast and precise machining with significantly less material consumption compared to bonded block materials. With Close Contour Pastes, Rampf enables seamless production of large-scale models and molds with fine surfaces and high temperature resistance. These can be easily processed manually or via CNC and cure quickly at room temperature. Infusion and laminating resins are low-viscosity epoxy resin systems with good flow behavior, optimal fiber wetting, and reliable vacuum processing for high-temperature-resistant composite components. Additionally, Rampf offers structural resins that can be processed at low temperatures, reducing tooling and development costs. The resins are scalable from prototype to series production and compatible with all Raku Tool board materials; they are available in formulations meeting FAR 23.1193, FAR 25.853, and FAR 25.855 FST requirements.

Reactive, Design-Integrated Surface

Covestro, Marquardt, and E Ink have combined their expertise to develop responsive, design-integrated surfaces for vehicle interiors. This involves a fully transparent film based on the water-based INSQIN PU technology using Impranil DLC-F. Impranil DLC-F is a water-based polyurethane dispersion commonly used in the top layer of textile coatings for vehicle interiors. The result of their joint effort: a transparent coated plastic surface that preserves the high-quality feel of automotive textiles while fully showcasing the dynamic colors of the display, simultaneously meeting the various high-performance requirements of vehicle interiors. The solution is intended to be used in the door interior panel of the concept car "The Centum," developed by Marquardt. The "The Centum" door panel combines adaptive color functions with the premium look and feel of PU-coated textiles for vehicle interiors.
