Comparing the Effects of Ultraviolet and Fiber Lasers on Materials

In practical tests, UV lasers are superior in terms of fine processing and handling of sensitive materials, which makes them ideal for the electronics and medical industries. Fiber lasers, on the other hand, are better for metal processing, and are more cost effective, which makes them better suited to mass production.Each of these two techniques has its advantages, and the choice between them must be made by considering the properties of the material and the production requirements.

Precision comparison.

In practical tests, UV laser marking machines have been shown to be superior to CO2 lasers for fine processing.For example, when carving out a two-dimensional barcode 0.1 millimeter deep in a metal surface, the UV laser produces a sharper edge, while the fiber laser leaves a slight burn mark.However, for metals thicker than 2 mm, fiber lasers have the edge in both speed and cutting power.

Differences in material adaptability.

Sensitive materials expression.

Materials such as plastic and glass, which can easily be deformed by heat, are virtually unaffected by the cool UV laser.When testing the marking of acrylic, ultraviolet lasers preserve the original color of the material, whereas fiber lasers cause the edges to turn yellow.

It has a metal processing effect.

The fiber laser is even more efficient at processing common metals such as stainless steel and aluminum alloys.In particular, the fiber laser can carve a depth of 0.5 mm in a single pass, whereas the UV laser requires multiple passes.

Long-term cost analysis.

Although the purchase price of UV laser equipment is about 30 % higher, it is more advantageous in terms of the frequency of replacement of consumable materials.After working continuously for 2000 hours, the power of the ultraviolet laser drops by only about 5 %.For factories that operate at high frequencies every day, the total costs over three years may be even lower.

Suggested industries.

For marking electronics or medical devices, where high precision is required and the materials are highly sensitive, ultraviolet lasers are a safer choice.The price-performance advantage of fiber lasers is even clearer in the mass production of car parts, tools, and other items that require efficiency.
