How To Choose The Right Power Fiber Laser Marking Machine

In order to select the appropriate power fiber laser marking equipment, it is necessary to comprehensively consider the influencing factors. The factors affecting the marking depth include material properties, material, hardness, surface finish, laser power, scanning speed, filling density and number of scans.

Choose the right power fiber laser marking on metal:

• Material Characteristics: Different materials have different absorption efficiencies of the laser, which directly affects the final results of marking. In general, metal usually absorbs more laser energy than plastic, which requires higher power to mark metal. Most metals have better absorption for 1060nm, so 1060nm fiber laser is more suitable for metal materials.

• Hardness: Harder materials require higher laser power or more scans to achieve the same marking depth. Some metals or specially treated metals are relatively hard, low power laser is difficult to engrave on the surface, increase the power marking will be easier. There is also the use of laser spray, similar to brilliancelaserinks technology, this technology is very suitable for those difficult to use low-power laser engraving metal.

• Surface finish: Smooth, highly reflective surfaces require laser power and parameters to be adjusted to ensure that the laser energy is absorbed efficiently and quality marking is achieved. Mirrored surfaces reflect laser light, resulting in less laser light being absorbed by the surface and less effective engraving. Reflected laser light can damage the laser components and the operator to a certain extent, so the operation must pay attention to safety precautions. Short wavelength laser is more suitable for high reflection materials, such as precision stainless steel, brass, copper, aluminum alloy, gold and other materials.

• Laser power: Higher power lasers can mark faster and deeper, but need to strike a balance between thermal effects and marking quality to avoid overheating or damage to the material.

• Scanning speed: Slower scanning speeds allow the material to absorb more laser energy, which increases marking depth, but this can also reduce productivity.

• Filling density: Higher filling density increases the laser coverage area and improves marking depth and uniformity, but it also increases processing time.

When choosing a fiber laser marking machine, it is necessary to comprehensively consider the specific needs of the customer to ensure that the marking effect meets the requirements, while maintaining efficient, high-quality production
