The art of high precision

At the heart of this collaboration is the agility of a human-sized structure combined with cutting-edge equipment. In his 400 m² facility located in Charvonnex, Nicolas Pennamen operates machines capable of meeting the demands of the most exacting sectors such as watchmaking and jewelry. 

Usinage CNC 5 axes de haute précision pour matériaux compositesFront-loading machining center

This expertise is particularly evident in our 5-axis CNC machining, which enables us to produce complex geometries while ensuring flawless repeatability.

Whether for the processing of metals or composite materials, such as carbon fiber or fiberglass, each step is guided by a quest for absolute rigor. This technical expertise enables us to achieve very precise overall tolerances (± 0.02 mm) in our materials, a requirement that is essential for cutting-edge industries. From grinding to finishing and assembly operations, each part receives special care, including a systematic cleaning process to ensure a perfect surface condition and impeccable technical compliance.


A vertical integration to meet your challenges

For Lavoisier Composites, this collaboration allows us to offer fully integrated services, breaking down the traditional barriers between the design office and the workshop. For our clients, this means comprehensive support from concept to production.

3D design interface and high precision control

By handling these finishing and complex machining steps in-house, we are able to meet the most demanding specifications with greater responsiveness. This direct proximity allows us to adjust prototypes in real time and ensure the industrial viability of each part, from single units to production runs. Our decision to manufacture locally in Haute-Savoie (France) reinforces our commitment to a local, high-performing, and responsible industry capable of transforming cutting-edge materials into finished components of exceptional quality.
