# JW Laser UV Laser Marking Machine Product Introduction<br /> <br /> JW Laser UV laser marking machine adopts **355nm UV cold laser**, utilizing intra-cavity tripling frequency technology to achieve photolytic cold etching processing, differing from the thermal ablation mode of fiber and CO₂ lasers. It is a specialized high-end equipment for ultra-fine permanent marking in precision electronics, plastic, glass, and medical device industries, suitable for high-contrast, burr-free, and distortion-free precision engravings, supporting static marking and high-speed flying marking on production lines.<br /> <br /> ## ✅ Product Principle<br /> <br /> The 355nm short-wavelength UV laser has high photon energy, directly breaking the chemical bonds on the material surface for marking and engraving through **cold processing**, rather than relying on high-temperature burning. The heat-affected zone is extremely small, nearly free of thermal deformation, slag, charring, or edge cracking. The beam spot is fine, and the lines are sharp, making it suitable for heat-sensitive, transparent, and brittle precision substrates.<br /> <br /> ## ✅ Core Advantages<br /> <br /> 1. **Cold Processing, No Material Damage**<br /> No obvious thermal effects, solving common issues from conventional laser marking such as yellowing, bubbling, cracking of plastics, edge cracking of glass, or coating damage. Transparent, thin-walled, and soft rubber parts maintain a clean and transparent surface after processing.<br /> 2. **Ultra-Fine Beam Spot, Extremely High Precision**<br /> Outstanding beam quality with a focused spot size, enabling the engraving of micro QR codes, serial numbers, LOGOs, precision characters, and micron-level patterns. Marked edges are sharp, high-contrast, and wear-resistant, meeting high-end product traceability and anti-counterfeiting requirements.<br /> 3. **Wide Material Compatibility**<br /> High absorption rate for polymer materials, making it easy to achieve high-definition marking on materials that are difficult to process with conventional fiber machines.<br /> 4. **High Speed and Stability, Suitable for Mass Production**<br /> High-speed galvanometer scanning system for fast marking, water-cooled constant-temperature laser, stable power output for long-term continuous operation, and high repeatability accuracy, compatible with production line flying marking, rotating fixtures, and automatic loading/unloading.<br /> 5. **Intelligent System, Simple Operation**<br /> Industrial touch control marking software supporting text, barcodes, QR codes, vector graphics, variable serial numbers, and automatic date jumps; process parameters can be saved and called with one click; built-in laser safety protection, emergency stop, power monitoring, and fault alarms.<br /> 6. **Eco-Friendly and Durable, Low Maintenance**<br /> Oil-free and consumable-free, no solvents required; long-lasting laser life with low maintenance costs; markings are permanent, resistant to friction, acid, alkali, and high temperature.<br /> <br /> ## ✅ Materials Suitable for Processing<br /> <br /> PC, ABS, PP, Nylon, Silicone, Rubber, Epoxy Resin, Transparent Plastics; Glass, Quartz, Ceramic, Sapphire; PCB Circuit Boards, FPC Flexible Circuit Boards, Silicon Wafers; Plated Layers, Coatings, Anodized Layers; Some Thin Metals, Medical Consumables, Food and Drug Packaging Films, Paper Films, etc.<br /> <br /> ## ✅ Typical Application Industries<br /> <br /> - 3C Electronics: Data cables, charging heads, connectors, chips, capacitors/ resistors, LCD screens, plastic casings with QR code traceability<br /> - Medical Devices: Syringes, surgical consumables, medical plastic parts, medical glass reagent bottles (meets pharmaceutical traceability requirements)<br /> - Packaging and Daily Chemicals: Cosmetic bottles, medicine bottles, transparent packaging, anti-counterfeiting markings<br /> - Optics Industry: Lenses, glassware, crystal, optical components for internal and surface marking<br /> - Automotive Electronics: Automotive interior buttons, sensors, wire harness terminals, plastic parts<br /> - Home Appliances, Sensors, Laboratory Instruments, Precision Metal Plating Engraving<br /> <br /> ## ✅ Machine Configuration (Multiple Power Options Available)<br /> <br /> - 3W: Lightweight, suitable for extremely fine, low-sensitivity plastics, films, and small-character QR codes<br /> - 5W: Best-selling, high comprehensive cost-performance, mainstream choice for electronic parts, glass, and PCBs<br /> - 10W/15W: High-power UV, suitable for thick coatings, dark plastics, high-speed area marking, micro-cutting, and micro-hole processing<br /> <br /> > <br /> > Standard Configuration: Industrial water cooling system, high-speed galvanometer, positioning red light, protective goggles; optional rotation axis, flying marking module, automation integration, CCD vision positioning; supports CE certification, suitable for domestic factories, export orders, and global distributor placements.
