Micronora started yesterday and visitors can discover many microtechnology innovations. This morning, we put the light on a small French SME that presents amazing achievements in terms of micro-machining and micro-moulding.
Vuillermoz Philippe SAS has developed an encapsulated micro screw for one of its Swiss customers. It is an essential element for an innovative system of high-end mechanical watch movement. A patent has been filed and is pending.
Micromachining? It is certain.
The challenge faced was huge in terms of research and development, micro-machining and micro-injection where the tolerance on the diameter of the moulded part is 0.99 mm + 2 /-3 µ. The specialists of the company have done it and the parts are perfectly meeting the requirements. The company spokesman says: “Our customer was delighted as the result surpasses his expectations”. Despite of being a small company, every aim was respected (quality, technique, delivery time).
Knowing that a gross grain of material weight 0,02 gram, it allows the production of 14 molded parts. The weights are very light: the total weight of the encapsuled part is 0.0051 gram, the weight of the single insert is of 0.0037 gram, the weight of the material on the part is of 0.0014 gram.
These skills and parts can be discover until Friday (as well as many other things of course) in Besançon.
