RESEARCH & PRODUCTION

Laser Micro-Welding

Precise laser micro-welding enables the delicate structures that define Excellence Titan frames.

CHARMANT is a pioneer in applying advanced laser welding to eyewear manufacturing. Before this technology was introduced, traditional joining methods compromised either the strength or the appearance of frame components. In collaboration with Osaka University, our researchers dedicated more than five years to refining and adapting laser micro-welding technology. The result enables frame structures that combine exceptional flexibility, light weight, and refined aesthetics.

The joining points are finished so precisely that the connection is nearly invisible, creating a clean and elegant appearance.

Frame components are joined without filler metals. Concentrated heat reduces thermal impact and preserves the material’s original properties.
