What should I pay attention to when buying a laser marking machine?

One:Technology and Performance

• Fiber laser marking machine: Suitable for metals and some rigid plastics, with a wavelength of 1064nm and high absorption, suitable for high-precision marking.
• CO2 laser marking machine: Suitable for non-metallic materials, with a wavelength of 10.6μm, suitable for the packaging and handicraft industries.
• UV laser marking machine: Suitable for sensitive materials, due to its cold working properties, minimizing thermal damage, and suitable for microelectronics and medical devices.

Power and Speed

• Fiber laser: 20W-50W is suitable for most metal marking, 100W and above for deep engraving.
• CO2 laser: 30W-60W is suitable for non-metals, 100W and above for cutting.
• UV laser: 3W-10W is suitable for precision marking.

Precision and Resolution

• Fiber laser: Resolution up to 18 microns, suitable for precision marking.
• CO2 laser: Larger spot size, slightly lower precision, suitable for large-area patterns.
• UV laser: Smallest spot size (approximately 10-20 microns), suitable for ultra-high precision.

Work Area and Processing Dimensions

• Desktop Models: 100 x 100 mm or 200 x 200 mm, suitable for small parts.
• Industrial Models: 300 x 300 mm or larger, suitable for large batches or large workpieces.

Two: Cost

• Fiber laser: 20,000-100,000 RMB (20W-100W), with imported brands (such as IPG fiber) being more expensive.
• CO2 laser: 15,000-80,000 RMB (30W-100W), with glass tubes being cheaper and RF tubes being more expensive.
• UV laser: 100,000-300,000 RMB, with the highest cost due to its complex technology.
