Structural assembly – the highest
precision components

Our services

Partner­ship – our basis for quality

There is a reason why Kaelin components exhibit the highest precision and technical maturity: our claim is as clear as our results – only top quality counts.
We are certified supplier to EASA part 21/G manufacturing companies; our quality sytem is EN 9100 compliant. We work with our customers on an equal footing; we rely on mutual partnership, exact implementation of the manufacturer's specifications and absolute punctuality.

Quality is convincing: for years we have been a permanent partner of the Swiss Pilatus Flugwerke AG and successfully produce numerous components for different Pilatus models. Their PC-24 business jet alone accounted for around 50,000 hours of working time in 2018. A positive signal for us: we are not only a competent partner – we also have the manpower to reliably implement all requirements. If you are interested in our quality policy and goals, we look forward to hear from you via the contact form.
