Zhongshan LED lamp laser marking machine laser coders LED drive casing (Shaw 189-8857-7595 / 180-3816-4716 welcome to inquire) fiber laser engraving machines generally use fiber laser, capable of a variety of metals and some non- laser engraving on metal, including mild steel and stainless steel, inconel and titanium. Because fiber lasers and fast pulse rise time and high beam quality, which is particularly suitable for metal marking. This laser can be used with galvanometer marking the first combination constitutes a pocket-sized package system. Marking on the metal usually used 20W fiber laser, from the time when the material factors focused laser beam, due to the surface oxidation of the formed color mark, mark type is formed by laser energy input, the protective gas and the marking materials used in the decision . Because the marking on the metal is a high energy process, and therefore the smaller spot size, the shorter the focal length, the quality of play, the higher mark, marking cycle is relatively short. But this should reduce the cost of the entire range of marking. For stainless steel products, the greatest practical spot diameter of 300mm, a minimum of about 100mm. Obviously, the lens focal length and marking range maximization can significantly shorten the laser engraving or laser engraving of the time.
