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. ![UV Laser Marking Machine]() ### Advantages of UV Laser Marking Machine 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. ### Applications of UV Laser Engraving Machine 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 two-dimensional code marking, glassware surface drilling, metal surface coating marking, plastic buttons, electronic components, gifts, communications equipment, building materials, etc. **Types of Plastic You can Engrave with UV Laser Marking Machine** Silicone. Polyamide (PA). Polyimide (PI). Polyester (PES). Polystyrene (PS). Polyethylene (PE). Polypropylene (PP). Polycarbonate (PC). Polyoxymethylene (POM). Poly ether ketone (PEEK).

R #### _Rolland_ _4_ out of 5 Reviewed in France on 2022-08-29 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. C #### _Charles_ _5_ out of 5 Reviewed in the United States on 2020-02-23 I don't write a lot of reviews but I'm compelled to write this review. The UV laser engraver has worked great for what I use it for. I use it to engrave polyethylene, polyamide, ABS and many other plastics. I love this laser machine. #### Leave Your Review 1 to 5-star rating5 stars4 stars3 stars2 stars1 star ##### Share Your Thoughts with Other Customers Review Title Your Name Your Email Your Review Guest Post Captcha ![Click To Change Captcha]() Submit Your Review ## Further Reading ### No Previous Product Available ### Desktop UV Laser Marking System for Plastic, Silicon, Glass STJ-3U[Next Product](https://www.stylecnc.com/uv-laser-marking-machine/uv-laser-marking-system.html "Desktop UV Laser Marking System for Plastic, Silicon, Glass") ## Related Stories ![How to Install & Use EZCAD for Laser Marking Machine?]() 2026-06-08By Jimmy ### [How to Install & Use EZCAD for Laser Marking Machine?](https://www.stylecnc.com/cnc-software/ezcad.html "How to Install & Use EZCAD for Laser Marking Machine?") ![How To Setup A Laser Marking System for Beginners and Pros?]() 2025-01-06By Jimmy ### [How To Setup A Laser Marking System for Beginners and Pros?](https://www.stylecnc.com/user-manual/Laser-marking-machine-system-setup.html "How To Setup A Laser Marking System for Beginners and Pros?") ![A Comparison of Laser Engraver, Laser Etcher, Laser Marker]() 2024-04-02By Charles ### [A Comparison of Laser Engraver, Laser Etcher, Laser Marker](https://www.stylecnc.com/user-manual/A-comparison-of-Laser-engraving-etching-marking-machine.html "A Comparison of Laser Engraver, Laser Etcher, Laser Marker") ![How to Buy Laser Engraver Cutter for Custom Jewelry Maker?]() 2024-01-02By Charles ### [How to Buy Laser Engraver Cutter for Custom Jewelry Maker?](https://www.stylecnc.com/blog/jewelry-laser-engraver.html "How to Buy Laser Engraver Cutter for Custom Jewelry Maker?") ![Daily Maintenance for Fiber Laser Marking Machine]() 2023-10-07By Jimmy ### [Daily Maintenance for Fiber Laser Marking Machine](https://www.stylecnc.com/user-manual/Daily-maintenance-of-fiber-laser-marking-machine.html "Daily Maintenance for Fiber Laser Marking Machine") ![Fiber Laser Engraving Machine for Consumer Electronics]() 2023-10-07By Jimmy ### [Fiber Laser Engraving Machine for Consumer Electronics](https://www.stylecnc.com/cnc-solutions/Laser-engraving-machine-and-laser-marking-machine-used-in-consumer-electronics.html "Fiber Laser Engraving Machine for Consumer Electronics") ## Related Products ![Desktop UV Laser Marking System for Plastic, Silicon, Glass]() STJ-3U 4.9 (33) $5,400 - $6,500 ### [Desktop UV Laser Marking System for Plastic, Silicon, Glass](https://www.stylecnc.com/uv-laser-marking-machine/uv-laser-marking-system.html "Desktop UV Laser Marking System for Plastic, Silicon, Glass") ![Battery-Operated Portable Handheld Fiber Laser Engraver]() STJ-20FB 4.8 (57) $1,500 - $2,500 ### [Battery-Operated Portable Handheld Fiber Laser Engraver](https://www.stylecnc.com/fiber-laser-marking-machine/portable-fiber-laser-marking-machine.html "Battery-Operated Portable Handheld Fiber Laser Engraver") ![2026 Best Laser Engraver for Gun Stippling & Grip Texturing]() STJ-50F-S 4.9 (19) $2,400 - $6,500 ### [2026 Best Laser Engraver for Gun Stippling & Grip Texturing](https://www.stylecnc.com/fiber-laser-marking-machine/laser-engraving-machine-gun-firearm-weapon.html "2026 Best Laser Engraver for Gun Stippling & Grip Texturing") ### STYLECNC
