Located in the high-tech hub of Hangzhou, Kinray Laser benefits from direct, rapid access to premium component clusters. From industry-leading light sources (Raycus, Max, JPT) to precision optical lenses, galvo scanners, and robust linear stages, this concentration keeps material costs low and production lead times exceptionally short.
We don't just assemble parts. Every fiber laser system undergoes advanced beam profiling, power calibration, and rigorous high-temperature endurance runs. Our engineers inspect galvo drift and focal alignment with micron-level testing fixtures, ensuring long-term field stability that equals or exceeds western competitors.
Our products are engineered to conform with rigorous international standards, including CE, FDA, and RoHS directives. Kinray's systems feature proper EMI shielding, standard protective ground connections, safety interlocks, and dedicated laser safety glasses to guarantee compliance and user safety at global facilities.
A comprehensive whitepaper analysis of emerging laser marking innovations and strategic application architectures.
For many years, standard Q-switched fiber lasers (wavelength 1064nm) were the industry workhorses for generic metal engraving. However, the rise of modern industrial materials demands highly dynamic and precise thermal management. This is where MOPA (Master Oscillator Power Amplifier) technology excels. MOPA lasers allow operators to adjust pulse duration (ranging from 2ns to 500ns) independently of pulse frequency. This enables black marking on anodized aluminum, high-contrast marks on medical plastics, and color marking on stainless steel by fine-tuning the heat input.
Manual alignment represents a significant bottleneck in high-throughput production lines. To address this, modern factories are adopting Auto-Alignment Fiber Laser Marking Systems integrated with industrial cameras. Coaxial and off-axis camera configurations use machine vision algorithms to detect part position, orientation, and dimensions automatically. This allows the galvo system to realign the marking pattern on the fly, eliminating the need for expensive physical jigs and ensuring error-free marking on small components like microchips, medical needles, and connector terminals.
Today's production lines require continuous marking on the fly (MOTF) at speeds exceeding several hundred meters per minute. Kinray's flying laser markers integrate seamlessly with high-speed extrusion lines, bottling plants, and wire harness assemblies. Furthermore, the advent of 3D Laser Marking systems equipped with dynamic focusing systems has revolutionized the marking of curved, spherical, and sloped surfaces. By adjusting the focal length in real-time, 3D laser scanners maintain precise beam spot sizes across complex 3D surfaces without requiring physical axis rotation.
Unlike traditional ink-jet printers, chemical etching, or physical stamping, fiber lasers do not require consumables, inks, or harsh solvents. With low power draw (typically under 600W for a standard 30W setup) and a lifespan of up to 100,000 operational hours, fiber lasers represent one of the cleanest and most cost-effective technologies for product traceability and green industrial compliance.
How global industries apply our fiber laser marking machines to solve complex traceability problems.
Permanent marking of safety-critical parts (engine blocks, chassis parts, brake components, and tire molds) with durable, deep-etched 2D DataMatrix codes. Designed to survive extreme friction, heat, and coating processes.

Recommended Power: 20W - 30W MOPA / UVCorrosion-resistant marking of surgical steel, titanium implants, and pharmaceutical-grade packaging. Marks withstand autoclaving, chemical washes, and standard medical sterilization protocols.
Recommended Power: 20W - 30W JPT MopaGet professional answers from Kinray's engineering team on selecting, operating, and maintaining fiber laser systems.
Q-switched fiber lasers (like standard Raycus and Max systems) have fixed pulse durations and are ideal for general marking, metal engraving, and deep etching. MOPA (Master Oscillator Power Amplifier) fiber lasers (like the JPT M7 series) offer variable pulse durations, allowing you to tune the heat input. MOPA lasers are essential for color marking on stainless steel, high-contrast marking on anodized aluminum, and marking on delicate plastics without melting them.
20W: Best for surface marking, thin metal engraving, plastic marking, and barcode etching.
30W / 50W: The industrial standard. Excellent balance between speed and depth. Ideal for deep engraving on steel/aluminum, jewelry cutting, and faster cycles.
100W+: Designed for high-speed industrial lines, deep molds, tire marking, and rapid material removal.
Yes. However, the results depend on the type of plastic and the laser's pulse width. ABS, Polycarbonate (PC), and Nylon (PA) typically mark well with standard fiber lasers. For thermal-sensitive plastics like PE or PP, a MOPA fiber laser or a UV laser is recommended to achieve high contrast without burning or bubbling the material.
Our standard systems support EZCad2 and EZCad3, which are compatible with popular design formats including DXF, BMP, AI, DWG, PLT, and DST. They run on Windows 10/11 and easily integrate with databases and automation controllers for barcodes, serial numbers, and variable text generation.
Fiber laser sources are solid-state and virtually maintenance-free. They do not contain flashlamps, gas tubes, or mirrors that require alignment. Under normal operating conditions (clean environment, stable voltage, adequate ventilation), the laser source has an estimated operating life of 100,000 hours, equivalent to over 10 years of continuous operation.
