Jewellery Laser Marking Machine: Case Study

A luxury watch manufacturer in Geneva faced challenges marking serial numbers and logos on titanium and gold components. Traditional engraving methods caused micro-fractures and required post-processing to smooth edges. Surface distortion affected the precision fit of delicate parts, leading to increased rejection rates.

They adopted a fiber laser marking machine with a 30W MOPA source and galvo scanner. The laser delivered high-contrast, permanent marks without mechanical stress or material removal. Fine features like QR codes and intricate hallmarks were marked in under 8 seconds per piece.

Operator training took less than a day, and integration into the existing production line was seamless. The non-contact process eliminated tool wear and reduced consumables, cutting maintenance costs by 60%.

The laser’s pulse width control allowed safe marking on thin substrates without warping. With adjustable frequency and peak power, operators achieved matte, annealed, or high-gloss finishes for brand-specific aesthetics.

Annual throughput increased by 180%, enabling the facility to fulfill rush orders without overtime. The machine paid for itself within 11 months through reduced labor, scrap, and consumable costs. Klear Laser’s solution proved not only precise but also a strategic efficiency driver in high-end jewellery manufacturing.

Principales características y ventajas

The Klear Laser jewellery marking machine uses a high-performance IPG fiber laser source. It offers adjustable pulse frequency from 20-200 kHz for precise material control. This prevents thermal damage on delicate gold and silver surfaces.

The precision galvo scanning head features a 20µm spot size and 7000 mm/s speed. Advanced optics ensure consistent focus during high-speed operations. Minimal heat input maintains substrate integrity for intricate designs.

Air-cooling maintains stable temperatures during prolonged use. This ensures consistent marking quality in high-volume production environments.

Aplicaciones industriales

Jewellery laser marking is rarely found on an auto or aerospace production line, but the underlying technologies—fiber MOPA engines, 144 mm ZnSe lenses, and 0.001 mm galvo accuracy—were perfected for turbine blades and fuel-injector nozzles before being miniaturised for hallmarking rings. That same pulse-on-the-fly control lets us melt a 10 µm trench on a 24 kt bangle without removing the polishing film next to it, so tier-one suppliers borrow our recipes when they need to put 2D codes on gold-plated connector pins inside a satellite.

Marine applications centre on anti-counterfeiting: luxury yachts now laser-seal every 18 ct white-gold railing clamp with a unique nanographic code that survives 1 000 h salt-spray. The same MOPA source that anneals a deep black mark on a platinum engagement ring is also used to put UV-readable serials on titanium shackles that will live under 40 m of seawater.
