Ultraviolet laser marking machine is a type of cold laser engraving system for ultra-fine printing on plastic, polymer and silicon, as well as glass and metal.
STJ-3U UV laser marking machine is a cold engraving tool using third-order intracavity frequency doubling technology for fine engraving of metal, plastic, glass, silicon wafer, film, silica gel and fruit. The frequency of the laser generated by the pump is doubled to generate a 355nm short-wavelength ultraviolet laser beam. The computer controls the high-speed scanning galvanometer to deflect and change the optical path of the laser beam to realize automatic marking. In addition, it can be combined with the automatic control system to automatically load and unload materials, and automatically feed in and out materials to realize assembly line operations.
• Integrated modular structure design, easy to operate and humanized.
• Excellent beam quality, creating ultra-high-precision engravings, the beam quality is much better than traditional solid-state laser marking machines, for the fundamental mode (TEM0O) output, the focus spot diameter is small, the minimum character height is 0.3 mm, and the width is 0.03 mm, professional for fine and precise marking.
• Using high-speed scanning galvanometer, the marking speed is fast, the efficiency is high, and the time cost and labor cost are saved.
• Water-cooled design, maintenance-free, high electro-optical conversion efficiency, energy saving, low cost of use, no consumables are required.
• The mark is environmentally friendly, permanent and does not fade, and complies with RoHS standards.
• The marking software is powerful, compatible with file formats such as PLT, DXF, AI, DST, BMP, JPG made by CorelDraw, AutoCAD, Photoshop and other CAD software, and supports automatic coding, printing of serial numbers, batch numbers, dates, barcodes, QR codes, and automatic skip numbering.
• Easy maintenance, long service life, small size, space saving, and suitable for working in harsh environments.
UV laser marking machines are used to etch and engrave most metal and non-metal materials such as plastic, wood, metal, ceramics, glass and crystal, as well as the surface treatment of highly flame-retardant materials. In addition, inks, paints, and sprayed materials can be stripped and processed much cleaner than fiber optics, with neat edges, less burrs, and no burnt phenomena.
Ultraviolet laser marking machine is used in electronic equipment, watches, personal computers, metal gifts, electrical products, PCB, control panels, nameplates, hardware products, instruments, precision equipment, bathroom accessories, batteries, industrial bearings, molds, jewelry, jade and all walks of life for personalized engraving.
