Who is Cadaix

Stéphane Auffray , a training plastic worker,

Since 1997 I have built a solid experience in the development of technical products, in contact with major industrial groups.

My specialty is plastics.

My experiences in environments require like the automobile , the medical or the sport have allowed me to diversify my areas of expertise and to solve many problems.

Complex plastic-based developments , which can often involve other technologies such as metallurgy, "synthetic materials / ceramics", motorization, optical integration or electronics, etc.

I decided to put take advantage of this experience and support small and medium-sized businesses in their quest for a well-developed, well-produced and cost-effective product

"Let's discuss and define together your project framework and resources"


During meetings, I also realized that many companies without specific expertise in plastics and without any link with industrial players.
Many of them do not suspect the complexity of this business and the issues they will face.
My role is to analyze your project , bring you my expertise in plastics , while relying on strong bonds woven during these years. From MADE IN FRANCE to LOW COST , I am able to build turnkey, technically sound and economically realistic files.

If the product requires it, it can be considered all the stages of a complex development ( studies, simulations, prototyping, physicochemical tests , ...).

Everything is a question of specifications.


  • Prototyping - sourcing - processing - plastic welding - ceramics - plastics - integration - injection tools - development strategy - low cost - quality development - cost study - materials
  • Technical plastics and convenience.
  • Complements and complementary processes (paints, plastic welding, markings, assemblies)
  • Integration of plastic products into complex assemblies


  • Medical : Hematology Devices, consumables for the hospital environment (small and high rates, micro mechanics and skins).
  • Automotive: Interior parts, engine components, ...
  • Sport (creation of a brand of products for the middle of the Cycles: Skean )> protections of frame mtb elastomer (100% developed and produced in France ) referenced in more than 20 countries worldwide.
