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.

Ultraviolet Laser Marking Machine for Plastic and Metal


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.

UV Laser Engraving Machine for Plastic and Metal

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.

경제성과 관련하여 이 레이저는 내 창의성을 훨씬 더 확장할 수 있게 해주는 완벽한 마킹 도구입니다. 상자에서 바로 작업을 시작하는 데 필요한 모든 것이 포함되어 있습니다. 이 조각사는 개봉부터 시작까지 약 10분 정도 걸렸고, 금속과 플라스틱에 훌륭하게 작업했습니다. STYLECNC는 구매 후 약 1주일 후에 저에게 연락하여 제가 제품을 어떻게 사용하고 있는지 확인하고 제가 가진 모든 질문에 답변해 주었습니다. 이 자외선 레이저를 강력히 추천합니다. 사용하기 쉽고 창작을 시작하는 데 필요한 모든 것, 훌륭한 고객 서비스 및 저렴한 기계가 함께 제공됩니다.
