Hangzhou Kinray Laser Co., Ltd. stands as a premier China industrial laser marking machine manufacturer and a pivotal supplier of integrated laser power supply systems, serving critical sectors of global manufacturing. Operating from our advanced facility in Hangzhou, China, we specialize in high-stability fiber, UV, CO2, MOPA, and sub-nanosecond laser options. Our engineering core integrates fundamental research and development, smart manufacturing, and localized global deployment to drive next-generation laser innovations.
Our comprehensive portfolio is purposefully engineered to optimize production pipelines. By delivering high-reliability power regulation, advanced duty cycle control, and noise-isolated signal paths, Kinray systems guarantee exceptional pulse stability and beam profile consistency across diverse substrates. Our solutions are deployed worldwide to assist distributors, system integrators, and OEM partners in executing high-precision operations in electronics, medical technology, aerospace fabrication, and automotive assembly lines.
The contemporary industrial landscape demands absolute reliability from laser processing machinery. At the heart of every fiber laser marker, UV engraver, and high-frequency cutting system lies the Laser Power Supply System (LPSS). The LPSS dictates pulse shape accuracy, thermal dissipation profiles, and the ultimate repeatability of microscopic markings. Kinray Laser addresses these operational realities with customized engineering solutions designed for complex environments:
Kinray's specialized low-power, zero-noise UV power configurations support cold marking on delicate silicon wafers and double-sided PCBs. Safe, ultra-short pulses protect internal microcircuitry from thermal shock and copper layer delamination.
Designed for heavy metals, titanium alloys, and high-density polymers, our heavy-duty fiber power units manage variable duty cycles to maintain contrast on chassis, engine blocks, and safety components over decades of operational exposure.
Precision-pulsed energy controls surface modification parameters for surgical instruments and implantable devices. This prevents carbonization and oxidation, ensuring compliance with strict FDA sterilization standards.
Industrial laser systems demand highly stable power architectures. Traditional power designs suffer from high ripple voltages and slow transient recovery times, which degrade beam quality and cause erratic markings. Kinray Laser resolved this by redesigning our power supplies to incorporate Active Power Factor Correction (APFC) and advanced closed-loop feedback systems.
Our fiber and UV laser power modules integrate high-speed microcontroller units (MCUs) that monitor real-time output currents at sub-microsecond intervals. In high-power fiber systems (20W to 100W), our power supplies deliver clean, noise-isolated DC lines directly to the pump diodes. This minimizes electromagnetic interference (EMI) and stabilizes peak current regulation. In MOPA laser configurations, where pulse duration must adjust dynamically from 2ns to 500ns, our power grids respond within nanoseconds. This ensures uniform pulse energy across wide frequency ranges and prevents pulse-to-pulse jitter, ensuring clean, sharp mark boundaries.
Our systems maintain output current ripple below 0.1%, safeguarding diode arrays from thermal stress. Rapid over-current protection shuts down energy delivery in under 10 microseconds during system faults, preventing catastrophic optical damage.
Integrated temperature sensors communicate with cooling loops to adjust thermal output dynamically. This reduces drift caused by ambient temperature changes in non-climate-controlled factory environments.
Industrial deployment requires global product compliance. Our systems are engineered and tested to satisfy safety and performance regulations in Europe, North America, and the Asia-Pacific region. Every laser power supply and fully assembled marking machine satisfies CE directives (EMC 2014/30/EU and LVD 2014/35/EU), EN 60825-1 laser safety standards, and RoHS regulations.
We work closely with local distributors, system integrators, and OEM partners to simplify factory integration. Kinray provides detailed installation guides, electrical schematics, and SDKs for customized software integration. By matching local industrial line voltages—including 110V/60Hz configurations in North America and 220V/50Hz grids in Europe—our power systems eliminate the need for external voltage regulators, reducing installation costs and saving floor space.
Kinray's laser power supply and coding solutions excel in fast-paced production lines, handling high-speed data feeds and running continuously 24/7:
Our online flying laser markers use high-frequency power switching to apply clear alphanumeric tracking codes on high-speed PVC and PE cable jacket lines. Our technology prevents character deformation or overlapping at line speeds over 200 meters per minute.
Using a rotary feeding structure paired with a 10W UV laser system and automated camera checks, our systems mark cosmetic and beverage bottle caps with unique QR codes. Defective markings are flagged and rejected in milliseconds.
Installed directly on SMT lines, our high-precision UV markers trace PCB boards, FR4 substrates, and micro-plastics without introducing heat damage or micro-fractures in neighboring components.
As global manufacturing shifts toward Industry 4.0, Kinray Laser continues to innovate and adapt. Our R&D division is focused on three primary areas designed to keep our systems at the forefront of the industry:
Integrating machine-learning models directly into our power supply controllers to predict component wear. By tracking voltage deviations, the system alerts operators to schedule maintenance before faults occur, minimizing unscheduled downtime.
Developing GaN-based power supply switches to improve energy conversion efficiency. These switches help reduce heat generation and overall footprint by up to 35%, supporting compact, air-cooled desktop laser systems.
Advancing our power supply control loops to handle pico- and femtosecond pulses. This enables precise cold material processing, essential for advanced medical implants and flexible electronic applications.
Our specialized production lines leverage clean-room environments and automated testing fixtures. These setups ensure every laser power supply system, fiber engine, and galvo head meets high standards of reliability and performance before delivery:
