THE FELSS GROUP

The Felss Group is a solution provider in the field of cold forming of metallic tubes and solid materials for the automotive industry. As lightweight construction experts, we develop optimal, sustainable solutions and processes for our customers: from product development and machines to the finished part in component production. Around 700 employees are already working with our customers today on the challenges of tomorrow. And they do so worldwide at our seven locations in Germany, Switzerland, the USA, China and Slovakia.

A holistic competence in the industry through Make & Buy–Felss supplies individual solutions for in-house production or the purchase of components. Here, Felss Systems stands for Make, i.e. mechanical engineering, including prototyping and engineering as well as their advanced development and implementation. Felss Rotaform stands for Buy and thus for the entire spectrum of component manufacturing with a global, energy-saving footprint, even in large-scale production.

Since May 2019, the traditional company HMP has been a part of the Felss Group, with headquarters in Königsbach-Stein. HMP is considered a specialist in rolling technology and thus adds another benefit to the Felss Group's range of services. The rolling technology is firmly integrated in the Felss Group and appears under the brand name HMP ROLLING.

Our ambition is to convince customers from different industries with resource-efficient, highly resilient and precise products. Whether for the automotive industry, medical technology, aviation or precision mechanics: Felss is a strong partner in the processing of metallic materials such as steel, aluminum or titanium along the entire process chain. From the blank to the ready-to-install component.

The right process for every requirement.

With our know-how in cold forming and many years of experience in the construction of machines for tube processing, Felss offers the appropriate technologies, processes and solutions for all problems.

Rotary swaging

The rotary swaging cold forming process enables the efficient and economical production of lightweight components. Several tool segments strike a workpiece simultaneously, repeating the process in quick succession. The material starts to flow and is formed with a high level of precision. The process is suitable for forming all kinds of external and internal geometries. The distinguishing feature of this technology is the way it allows maximum design freedom for visible and non-visible components alike. Rotary swaging is characterized by a wide range of forms and different degrees of deformation. It offers a much broader range of possibilities than most other cold forming processes. For instance, it is just as suitable for hose connection manufacturing as for the rapid, high-precision production of steering shafts, drive shafts, airbag cylinders or adjustment wheel drives.

Axial Forming

Axial forming is benifitial in lots of different applications but it is particularly beneficial for high-quality spline components requiring economical production processes. With the axial forming process, all spline dimensions are specified with maximum precision. Given that the teeth are an exact copy of the tool, there is absolutely no risk of pitch errors. The profiles are highly precise and the root circle radius is fully symmetrical, thereby increasing the fatigue strength considerably. Each component is produced within short process times and – in contrast to manufacturing processes that rely on cutting – the components become stronger as a result of the process.

Tube+

The Tube+ process developed by Felss is the first of its kind to allow partial tube thickening by cold forming. The process is used to complete preliminary steps with a view to simplifying other steps further along the process chain. It can be used to supplement rotary swaging or as an alternative to it.

HMP Rolling

Since acquiring the HMP companies in 2019, the Felss product portfolio now also includes a wide variety of rolling systems and technologies. Wire reduction rolling, flat and profile wire rolling, ultra-precision rolling, strip rolling or sectional rolling.
