Watchmaking
In the watchmaking industry, our EDM wires deliver ultra-precise gear cutting. These components are then strengthened through heat treatment and enhanced with a surface coating—improving both their aesthetic appeal and wear resistance.
The combination of heat treatment and surface coating achieves an unmatched level of perfection. By adapting each process to the specific materials and applications, we support our clients in developing tailor-made solutions that blend traditional craftsmanship with technological innovation.
EDM Wires
Ultra-precise gear cutting
Heat & thermochemical treatment
Optimization of the alloy’s internal structure for long-term durability and stability
Surface coating
Enhanced aesthetics and improved wear resistance
Aeronautics
In the aeronautics industry, our EDM wires ensure high-precision cutting of turbine blades, while heat treatment enhances their electronic and magnetic properties. A specific surface coating is then applied to protect them from oxidation and wear, ensuring long-term durability under extreme conditions. At the same time, our specialty wires support onboard systems by securing signal transmission and electrical connections in highly constrained environments.
