Research and development

iwis has been working for more than 15 years on the research and development of new leaf chains. We combine up-to-the-minute technology and assembly processes with optimum materials, coatings and geometry to constantly improve the technical characteristics of our products. 

Our chains are designed in close collaboration with end users and are available from different iwis production sites.

We offer the following customer services on request:

  • Wear analysis
  • Fatigue strength analysis
  • Tensile load analysis
  • Technical assessment tool available

We use in-house developed test stands and methods
to assure quality.
