Features of cold laser marking

● Stable performance, compact structure, small volume, light weight and easy to carry.

● Adopting built-in laser diode technology to avoid the effect of fiber jitter on the output laser.

● The heat-affected zone is extremely small, no thermal effect, no material burning problem.

● It is a cooled laser, marking on heat-sensitive plastic materials is very good and smooth, without causing any damage to the material surface.

● Electro-optical conversion efficiency is very high, reaching more than 30%, low cost of use, power saving and energy saving.

● The machine can be equipped with other optional accessories according to the customer's actual product laser marking needs, such as rotary device, 2D/3D worktable, pen rotary table and other fixtures.

Advantages of cold laser marking

1. High precision: UV laser has a shorter wavelength and can achieve finer and more precise marking effects. It can achieve high-precision carving of text, patterns and images, maintaining clarity and detail.

2. High-speed marking: With high marking speed, it can quickly complete large-area marking tasks and improve production efficiency.

3. High contrast: UV laser has high contrast on different materials. It can produce bright and clear marking effects on materials of different colors, making the marking results more distinctive.

4. Multi-material adaptability: Suitable for a variety of materials, including plastics, metals, glass, ceramics, electronic components, etc. Unlike other laser marking technologies, it can mark and engrave on a wider range of materials.

5. No thermal impact: Due to the high energy of ultraviolet laser, it can locally heat the surface of the material to vaporization or vaporization in a short period of time without causing obvious thermal impact on the surrounding materials. This helps avoid material deformation, damage or deterioration.

6. Non-contact marking: Using non-contact marking, the laser beam acts directly on the material surface without physical contact. This can reduce damage and deformation to the material during the scoring process.

7. Environmental protection and energy saving: It usually has low energy consumption. When using ultraviolet laser for engraving and marking, there is no need to use chemicals and solvents, which reduces environmental pollution.

Application materials of cold laser marking

It is suitable for almost all materials. Widely used in metal (all metals such as iron, copper, aluminum, magnesium, zinc, etc.), glass, crystal, PCB, plastic, fiber, paper, paint, silicon wafer, LCD, polyamide, wire, plug and other polymer materials.

Application industry of cold laser marking

Especially suitable for the high-end market of ultra-fine processing, skin care cosmetics, medical drugs, food, silicon wafer micro-hole, blind hole processing, glass products, metal products, plastic buttons, electronic components, gifts, communication equipment, building materials, etc.
