Product Marking: Technical Specifications

Industrial product marking has shifted from mechanical stamps and chemical etchants to wavelength-selective lasers that put permanent codes on metals, plastics and ceramics without consumables or post-cleaning. Fiber, UV and green sources give you the photon energy that breaks molecular bonds instead of melting bulk material, so you get high contrast, corrosion-resistant marks at micron scale. The trick is matching the wavelength to the absorption edge of the substrate while controlling pulse energy so you ablate only the coating or oxide layer and leave the base part untouched. KLEAR engineers run 1064 nm fiber for anodized aluminum, 532 nm green for gold connectors and 355 nm UV for white medical plastics because each material pair yields a different threshold fluence.

Pulse energy, not average power, determines mark depth and edge sharpness. A 1 mJ, 10 ns pulse from a MOPA fiber laser peaks near 100 kW and vaporizes 5–10 µm of stainless steel oxide, but the same 20 W CW beam only heats the surface until it discolors. By stretching pulse width from 4 ns to 200 ns we drop peak power by 50×, letting the heat flow laterally to darken anodize without penetrating the barrier layer—ideal for scannable DataMatrix on 6061 cases. Water-cooled UV lasers hold ±0.3 °C cavity temperature so the 355 nm line stays within 0.1 nm; air-cooled units drift 2 nm and the mark turns grey because the ceramic no longer absorbs efficiently.

Closed-loop chiller capacity scales with wall-plug waste, not just laser rating. A 20 W UV marker at 5 % electrical-optical efficiency dumps 380 W of heat, while a 100 W fiber marker at 35 % efficiency rejects only 190 W. KLEAR integrates 0.6 kW R-134a chillers for UV islands and 300 W passive radiators for fiber heads, keeping ambient coolant at 22 °C so condensation never forms on 355 nm crystals. The same chiller feeds the scan head aluminum housing, holding mirror drift below 3 µrad and maintaining <25 µm over a 200 mm field after eight hours of continuous QR coding on titanium dental screws.

Because every photon is delivered in a controlled pulse, KLEAR markers can anneal high-contrast black on 304 SS surgical tools at 80 kHz without adding Cr oxide thickness beyond 50 nm, keeping Ra surface finish <0.2 µm so bacteria cannot colonize rough crevices. The same source, tuned to 0.3 mJ and 4 ns, removes 3 µm of anodize on 7075 aerospace brackets to expose bright aluminum underneath, creating a high-reflectance UID that survives 1 000 h salt-fog yet leaves the 25 µm hardcoat intact for corrosion protection. With wavelength agility, pulse-on-demand energy control and thermally-stable chillers, laser marking replaces every legacy surface-altering process while delivering traceability that survives sterilization, fuel immersion and thermal shock from −55 °C to +150 °C.

Principais caraterísticas e vantagens

Klear Laser redefines product marking by utilizing advanced fiber laser technology to eliminate the need for toxic inks and solvents found in traditional printing methods. Our systems provide a permanent, non-contact solution that ensures traceability in the harshest industrial environments. This aligns perfectly with our mission to replace polluting manufacturing habits with clean, energy-efficient solutions.

At the core of our marking superiority lies the integration of premium laser sources from industry leaders like JPT and Raycus. We utilize MOPA (Master Oscillator Power Amplifier) architecture which allows for independent control of pulse duration and frequency. This technical capability ensures high contrast marking on sensitive plastics and stainless steel without causing thermal deformation to the substrate.

The beam delivery system features high-speed digital galvanometer scanning heads designed for extreme precision. These heads utilize mirrors with high reflectivity and low inertia to achieve marking speeds exceeding 7,000 millimeters per second. Coupled with high-quality F-theta field lenses, we guarantee consistent beam spot size and power density across the entire marking field to prevent distortion at the edges.

Our engineering team configures these components to handle distinct industrial requirements ranging from deep engraving to color marking on stainless steel. The combination of variable pulse width control and high-speed optics results in superior edge definition and cycle time reduction. Klear Laser ensures that your product identification meets aerospace and automotive standards for longevity and readability.

Aplicações industriais

Product marking using lasers is not a core capability of Klear Laser. Our industrial focus is exclusively on laser welding and laser cleaning systems. We do not manufacture or supply laser marking equipment for part identification or serialization.

Klear Laser solutions serve critical roles in automotive, aerospace, and marine manufacturing through precision welding and eco-friendly cleaning. Our fiber laser welders join structural components with minimal heat distortion, while pulsed laser cleaners remove contaminants without damaging sensitive substrates. These processes directly support quality control and part preparation stages within these demanding sectors.

The following table outlines key materials processed by Klear Laser equipment in these industries, emphasizing cleaning and welding applications instead of marking:

Our pulsed laser cleaning systems ensure substrate safety on aerospace alloys through controlled pulse widths below 200ns, preventing thermal damage. Fiber laser welders achieve consistent penetration in marine-grade stainless steel using Raycus sources and wobble optics for seam quality. This replaces chemical cleaning and TIG welding, eliminating hazardous waste in all three sectors.
