The difference between UV laser marking machine and fiber laser marking machine

With the continuous development of the laser industry, many customers do not know enough about lasers, they only understand the fur but do not know the meaning. There are many types of laser marking machines, and their performance is completely different. I have received many inquiries from customers, including those for marking and processing mobile phone shells, some for marking and processing glass cosmetic bottles, and others who need to engrave LOGO on egg shells and seafood shells. I receive many inquiries from customers for different products every day!

As a member of laser equipment, I tell everyone that laser marking machine is just a general term, laser marking machine includes (ultraviolet laser marking machine, fiber laser marking machine) Marking machine,) And these two kinds of marking machines have their own functions and characteristics!

1. Ultraviolet laser marking machine

Due to the extremely small spot of the focused light of the ultraviolet laser, And the processing heat-affected zone is very small, so ultra-fine and precise marking and special material marking can be carried out. As shown in Figure 1, it is the first choice for customers who have higher requirements for marking effects.

In addition to copper and metal accidents, UV laser is also suitable for processing many pharmaceutical markings.

The main advantages of UV are not only good beam quality, smaller focus spot, ultra-fine marking, extremely small heat-affected area, no heat effect, no material burning problem, fast marking speed, high efficiency, The whole machine has stable performance, small size, low power consumption and other advantages.

2. Fiber laser marking machine

The fiber laser marking machine evaporates the surface material through a laser beam to expose the deep material, which is caused by light energy. The chemical and physical changes of the substance 'carved' traces. It still burns off part of the substance through light energy, revealing various patterns such as patterns, texts, barcodes, etc. that need to be etched.

Suitable for metal products processing, because the fiber laser marking machine burns some of the material of the product through light energy, so it is a better choice for metal and stainless steel materials. If you have more demanding and more precise products , The fiber laser marking machine will appear awkward, and then we compare the UV marking machine with the fiber marking machine, do you think they are completely two performances!
