About Fiber Laser Marking Machine?
Laser marking uses a laser to make marks on the surface of various materials. And the result of marking is to expose the deep material through the steam of the surface material. Or to “carve” traces through the chemical and physical changes of the surface material, whats more to burn off part of the material through light energy to show the patterns and text.
The marking machine can mark a variety of metals, such as gold, silver, stainless steel, copper, aluminum, and brass. And alloys and metal oxides , such as anodized Al. And some non-metallic and special surface treatments, such as silicon wafers, ceramics, plastics, rubber, epoxy resin，PVC and ABS.
The use of MOPA laser smaller pulse width can make the material not easy to deform. And the shading is more delicate. This is because the MOPA laser uses a small pulse width to make the laser stay on the material shorter. And it has a high enough energy to remove the anode layer, so for the thin Al oxide plate surface to strip the polar anode processing, MOPA Laser is a better choice. MOPA laser has a wide range of pulse width and pulse frequency adjustment. Using narrow pulse width and high frequency can produce a black effect on the surface of the material. And different combinations of data can also mark different gray-scale effects. The MOPA laser can adjust the pulse width and frequency, which not only makes the line fine, but also the edges appear smooth and not rough.
