Material, precision requirement and budget are three core factors for model selection. Choose accordingly:
1.Fiber Laser (1064nm infrared, ideal for metals & hard engineering plastics)
✅Applicable materials: Stainless steel, iron, aluminum, copper, all alloys; hard plastics like ABS, PC, nylon, electroplated parts, hardware, auto spare parts, gold & silver ornaments.
✅Advantages: Nearly maintenance-free, fast marking speed, capable of black marking/annealing discoloration on metals, cost-effective.
❌Not suitable: Paper, leather, transparent PET & soft plastics (prone to scorching and blurry marking).
👉Application: Mass marking for hardware, auto parts, molds, metal components, 3C metal casings.
2.CO₂ Laser (10.6μm far infrared, ideal for most non-metals)
✅Applicable materials: Paper carton, leather, wood, acrylic, rubber, PET bottle, fabric, ceramic, ordinary glass, production date marking on food & medicine packages.
✅Advantages: Low procurement cost, high-speed large-area marking, clear color marking on nonmetals, top choice for packaging lines.
❌Not suitable: Most metals (laser reflected), ultra-thin thermal-sensitive plastic (easy to burn).
👉Application: Food & daily chemical packaging, wood engraving, leather logo, barcode marking on paper boxes.
3.UV Laser (355nm cold laser, ideal for precision & heat-sensitive materials)
✅Applicable materials: Transparent/thin-wall plastic, PCB, medical consumables (syringes, rubber stoppers), display glass, soft rubber, chips, thermal-sensitive plastic, tiny components; cold processing without thermal burning to avoid bubbling, deformation or yellowing.
✅Advantages: Highest precision (ultra-fine 0.001mm characters), zero thermal damage, specialized for tiny QR codes & micro characters.
👉Application: UDI marking for medical devices, precision electronic components, high-end transparent plastic, small-size high-precision marking.
