Explore our industrial-grade, certified laser systems designed for gold, silver, platinum, stainless steel, and fine gemstone marking.
An in-depth look at how luxury manufacturers, hallmarking offices, and automated factories integrate laser engraving technology.
Global jewelry hubs (e.g., Surat, Vicenza, Shenzhen, and New York) are subject to strict hallmarking laws like Dodd-Frank conflict minerals rules and ISO 9202 standards. Fiber laser systems provide permanent, high-contrast serialization, purity markers (such as Au999 or Pt950), and micro-QR codes down to 0.5mm x 0.5mm, ensuring foolproof traceability throughout the downstream distribution chain.
Unlike mechanical cutting or heavy acid etching, laser engraving is a non-contact photothermal process. When configured with custom coaxial fume hoods and high-efficiency particulate air (HEPA) gold-dust recovery systems, factories can reclaim up to 99.5% of vaporized precious metals, representing a substantial ROI factor over high-volume production schedules.
Precious alloys such as sterling silver (925) and rose gold are highly reflective and thermally conductive. Standard Q-switched lasers often run hot, which can cause micro-cracking and surface deformation. Utilizing advanced MOPA (Master Oscillator Power Amplifier) pulse technology allows pulse duration modulation from 2ns to 500ns, resolving localized heat build-up and securing flawless, distortion-free marks.
Choosing the correct laser setup is critical to output quality, cycle time, and material compatibility. Here is the technical breakdown used by top industrial designers:
Standard fiber lasers excel at direct deep engraving on brass, steel, and titanium. However, they lack the pulse control needed for high-reflectivity precious metals without causing discoloration or rough slag edges.
By allowing custom pulse-width configuration, MOPA systems let operators mark gold, silver, and platinum with minimal melting, producing high-contrast black engravings on silver, color marks on titanium, and clean micro-etchings inside rings.
Operating on a much shorter ultraviolet wavelength, UV lasers destroy molecular bonds directly instead of using thermal energy to melt materials. This cold process is perfect for gemstones, glass, pearls, wood, and organic polymer packaging without risk of heat fracture.

For modern smart factories (Industry 4.0), data integration and format flexibility are paramount. Our laser systems are built to natively support complex geometric data files, including DXF, PLT, AI, and DWG formats directly from standard CAD software packages like AutoCAD, CorelDRAW, and Illustrator.
This allows rapid setup times for customized batch orders. Coupled with 3D dynamic focus software and multi-axis rotary modules, the systems automatically parse rings, bangles, and watch bezels, dynamically adjusting the focal plane in real time to avoid design skewing on curved surfaces.
Ensuring compliance with international customs regulations and maintaining worker health and safety standards.
All machinery exported by Hangzhou Kinray Laser is certified under **CE, FDA (CDRH Accession numbers), and FCC** regulations, ensuring trouble-free customs clearance and full workspace audit compliance in European, North American, and Asian jurisdictions.
For high-traffic retail or lab environments, we provide optional Class 1 fully enclosed configurations with certified laser protective viewport glass, interlocked access doors, and exhaust ports to ensure compliance with OSHA and international safety guidelines.
Kinray supports distributors worldwide via secure remote SSH diagnostic links, video-guided alignment setups, and field service technician dispatch, assuring rapid resolution of alignment issues and minimizing production downtime.
Engineered for high-volume factories requiring heavy-duty continuous output and customized rotary integrations.
Providing clear, verified responses to the technical questions most frequently asked by procurement managers and design directors.
Standard Q-switched lasers have fixed pulse durations (typically around 100ns). When marking high-conductivity precious metals like gold or silver, this causes significant thermal buildup, resulting in melted burrs, slag, and potential metal loss. MOPA (Master Oscillator Power Amplifier) fiber lasers allow variable pulse width control (from 2ns to 500ns). This versatility enables precise heat input control, allowing high-contrast dark marks, color engraving on titanium/stainless steel, and minimal surface vaporization loss.
It depends on the application. For standard surface hallmarking, micro-marking, and barcoding, a 20W or 30W system is optimal. If your primary process requires deep cutting, nameplate engraving, coin mould routing, or fast metal removal, 50W or 100W systems provide higher material removal rates and shorter processing times.
Yes, our systems run on industry-proven controllers (such as EzCad or CNC controllers) which support universal file formats including DXF, PLT, AI, and DWG. You can export directly from AutoCAD, CorelDRAW, or Adobe Illustrator and feed the vector files straight to the marking software without format conversion errors.
We design specialized, sealed workspace chambers equipped with vacuum collection nozzles mounted directly around the focal point. This configuration extracts fine aerosol gold particulates into a multi-stage HEPA filters system. Once the filter is full, it can be incinerated at gold refineries to reclaim and recover the accumulated precious metal dust.
