STJ-5U UV laser marking machine is a type of cold laser etching system with Ultraviolet laser designed for ultra-fine marking for plastics, including polymer, silicon, ceramics, crystal glass, PC, PE, PET, and ABS. Now the 2025 top rated UV laser engraving machine for sale at affordable price.
UV laser marking machine is also called UV laser engraving machine, which has high beam quality and small spot, and the processing of heat affected area is small, which can be used for ultra-fine marking, special material marking. UV laser marking machine is suitable for processing more extensive materials, such as plastics, including PP (polypropylene), PC (polycarbonate), PE (polyethylene), ABS, PA, PMMA, silicon, glass and ceramics.
1. Perfect marking quality: 355nm output wavelength to reduce the thermal impact on the workpiece, high-precision galvanometer marking head can ensure fine and repeatable marking, high-precision fine spot to ensure the perfect marking results, The marking process is non-contact, the marking effect is permanent.
2. UV laser engraver machine has a large marking range.
3. Heat affected area is very small, there will be no thermal effect, the material is not deformed and charred.
4. High speed and high efficiency.
5. Machine performance is stable, small size, low power consumption.
6. The UV laser engraving machine is suitable for heat radiation reaction of large materials processing, if it's used for the production line with the automatic loading and unloading, it can realize automatic access to materials. It's suitable for the vast majority of metal and non-metallic materials on the marking industry.
UV laser engraving machine is mainly used in ultra-fine processing of high-end market, pharmaceuticals, cosmetics, video and other polymer materials, the surface of the bottle marking, the effect is very fine, marking cleaning firm, better than inkjet and no pollution, flexible PCB board marking, scribing, silicon wafer micropores, blind hole processing, LCD liquid crystal glass 2-dimensional code marking, glassware surface drilling, metal surface coating marking, plastic buttons, electronic components, gifts, communications equipment, building materials, etc.

This Ultraviolet laser kit is exactly what I need. It is a really convenient engraver for custom personalized glassware and drinkware, and it does a great job of that. My first project is etching a stemless wine glass (clear), and turned out excellent but not without trial and error.
