Top performance for the railway industry

with 30,000 km railway lines, more than 3,000 superstructure products and high-speed components for over 450 km/h.

Your global market leader for rail superstructure fastening components made of plastics.


Being a Q1 supplier of Deutsche Bahn and with fifty years of experience we meet any requirements regarding output, promptness and safety.

The Deutsche Bahn was our first customer. Since then and with long-term customer relationships we have steadily developed ourselves into the global market leader for injection molded parts in the rail superstructure business. Our rail fastenings, cable ducts and switch components ensure a secure freight- and passenger transport on any heavy-load- and high-speed lines worldwide, based on process reliable plastic solutions that are manufactured and assembled at our certified plants.

Speed and axle load determine technology and material.

Our plants process virtually all common constructional thermoplastics which are suitable for superstructure thanks to their elastic and load-bearing properties. Depending on the speed and specification we select the most efficient and useful injection process, including assembly- and refinement service upon request:

  • Joint development with customers
  • Mold design and construction
  • Thermoplastic injection molding and refinement
  • Individually automated assembly solutions
  • Global logistics solutions, directly to railtracks upon request

Superstructure reference projects.

Our wide product range includes more than 3,000 rail fastening components, such as angle guided plates, intermediate pads, dowels, switch components as well as cable ducts. They prove their worth in the initial equipment of railway lines, rail reconstruction or also maintenance.
