SED-ZWMJ5-G is a 5 W ultraviolet (UV) laser marking/coding printer using a 355 nm UV laser with third-order intracavity frequency-doubling. The very short wavelength focuses to a tiny spot and breaks molecular chains dir
Como funciona
A 355 nm UV laser (5 W average output, 30–150 kHz pulse repetition, <13 ns pulse width, M² < 1.2 beam quality) is delivered through a 10 mm digital galvanometer scanning system and an F=160 mm field lens. The galvanometer steers the focused beam at up to 10,000 mm/s across a 100×100 mm marking field; the cold UV photon energy directly breaks molecular bonds in the substrate, producing a high-contrast, fine, burn-free mark. A red-light 2-point assisted focusing system aligns the focal plane. An external trigger signal (photoelectric / encoder) and the touch-screen control system synchronise marking with the production line for on-the-fly coding (text, serial numbers, dates, shifts, QR/barcodes, vector graphics).

Limpeza e manutenção
Keep the laser head sealed and the field lens clean; no oil mist or condensation in the operating environment. The fully-sealed laser cavity has a self-cleaning system to reduce maintenance. Maintain the double-circulation water-cooling system at ±0.2 °C and replace cooling water periodically.
