The watch industry is not only the heir to artisanal craftsmanship, but also the perfect fusion of art and technology. While preserving traditional expertise, the sector is progressively adopting smart manufacturing technologies to enhance efficiency and precision—laser processing being one of the most advanced among them.
Laser Welding in Watchmaking
The trend toward miniaturization and automation has opened new applications for laser technology, particularly in laser micro-welding within the watch industry.
Laser micro-welding is a highly advanced and versatile technology, ideal for applications requiring exceptional precision and quality. Its operating principle is based on the high concentration of laser energy in an extremely small area, creating a highly localized fusion zone.
The limited heat input allows for weld seam widths below 200 micrometers, ensuring maximum accuracy and control.
These systems are especially valuable in daily workshop operations, enabling quick repairs of dents and minor damage to watch cases and bracelets, as well as more complex processes such as the full restoration of watches worn by previous polishing treatments.
Additive Manufacturing in Watchmaking
The Laser Metal Fusion (LMF) process, also known as metal 3D printing, is currently one of the most promising technologies in metal additive manufacturing. A high-intensity laser selectively melts metal powders following CAD design paths, creating fully dense three-dimensional metal components.
A wide range of materials can be used, including steel, titanium, bronze, gold, and platinum.
Laser Metal Fusion enables efficient production of highly complex geometries with fine internal channels and cavities, achieving exceptional quality standards.
