Take 3 minutes to quickly understand the mopa fiber laser marking machine
MOPA laser marking machine (aluminum black laser marking machine, color laser marking machine) belongs to the category of laser marking machine. Compared with the Q fiber laser, the pulse frequency and pulse width of the MOPA fiber laser are independently controllable. Through the adjustment and matching of the two laser parameters, the high-speed scanning galvanometer system can achieve a constant high peak power output and can be applied to a wider range of standards. Engraved substrate. With high-quality laser beam, low cost of use, maintenance-free for 100,000 hours, suitable for aluminum oxide blackening, 304 stainless steel coloring, stripping anodes, stripping coatings, semiconductor and electronic industries, plastics and other sensitive materials marking and PVC plastics In the pipe industry, the marked pattern fonts are environmentally friendly and comply with ROHS standards.
Application Name Q-Switched Laser Mopa Laser Alumina sheet surface peeling The substrate is easy to deform, form a convex hull, and the shading is rough Small pulse width, small heat residue, no deformation of the substrate, fine and bright shading Anodized aluminum black Only limited quality dusting possible Through the wide-area parameter setting, different shades of gray and black can be marked. Metal deep engraving Strong strength, suitable for deep engraving, rough shading The engraving depth is weak, but the shading is fine, the taper is small, and can be brightened coloring stainless steel Need to defocus, the effect is more difficult to adjust Various colors can be printed by adjusting the pulse width and frequency combination ABS and other plastic processing The effect is easy to yellow, feel heavy and fast No hand feel, not easy to yellow, delicate processing Translucent plastic key stripping paint difficult to clean Easy to clean, sharp edges, better light transmission, high efficiency PCB board marking bar code, two-dimensional code High single-pulse energy, but epoxy resin is more sensitive to laser energy Adopt small pulse width, medium frequency, bar code, two-dimensional code is clearer, not easy to remove and easy to scan However, when many customers purchase a MOPA laser marking machine, they expect its processing speed to be the same as that of an ordinary fiber laser marking machine, but this is obviously counterproductive. The two techniques are different. When engraving color effects, the machine needs to mark at high frequencies with minimal shadowing effects, which makes the engraving high resolution, but at the same time the engraving speed is relatively slow. In addition, MOPA laser marking machine may have no advantage in metal deep engraving, because there is no advantage in single-pulse energy, but in terms of delicate effect, it is much better than ordinary laser marking machine. Therefore, customers need to understand the advantages and disadvantages of this type of laser marking machine before choosing to buy a MOPA laser marking machine.
MOPA laser marking machine is suitable for fine marking process of metal and non-metal materials, such as laser engraving black on digital product parts, mobile phone back cover, IPAD, aluminum black marking, mobile phone buttons, plastic light-transmitting buttons, electronic components, integrated circuits ( IC), electrical appliances, communication products, sanitary ware, tool accessories, knives, glasses and clocks, jewelry, auto parts, luggage buckles, cooking utensils, stainless steel products and many other industries.
