Metal marking black is generally for stainless steel, stainless steel black, general laser marking machine can do, semiconductor laser marking machine, UV laser marking machine these can do. But for aluminum, the situation is not the same, aluminum can be hit into gray or dark gray, but can not hit more black. Copper also can not hit too black, can hit the clear is very good. That's what makes it so special. In fact, the real aluminum marking black is a special aluminum oxide laser marking machine it uses the laser is MOPA fiber laser, electro-optical conversion rate is high, compact size, good beam quality.
Aluminum oxide marking black laser marking machine and ordinary fiber laser marking machine is not the same, this laser marking machine with pulse width adjustable mode, the frequency can be adjusted to as high as 400Khz, you can directly hit the black effect of aluminum, magnesium aluminum, alumina, a variety of aluminum are universal, the current market of the Apple cell phone shell or ipad shell behind the small letters are useful for this aluminum oxide fiber laser marking machine to make out. Marking machine to do out.
Aluminum oxide marking black laser marking machine application scope:
Applicable materials: aluminum marking black effect, metal and a variety of non-metallic materials, high hard alloys, oxides, plating, coating, ABS, epoxy resin, ink, engineering plastics and so on.
Aluminum oxide laser blackening applicable industries:
Plastic translucent keys, IC chips, digital product components, precision machinery, jewelry, sanitary ware, measuring tools, watches and glasses, electrical appliances, electronic components, hardware jewelry, hardware tools, cell phone communication components, automobile and motorcycle parts, plastic products, medical equipment, building materials, tubes, and other high-precision product marking, recently popular, such as the Apple shell (iPhone), Xiaomi cell phone shell, millet mobile power supply LOGO, anodized aluminum, aluminum alloy, etc. are using this model, the effect is more ideal.
Aluminum oxide marking black laser marking machine use precautions:
1. laser spot size: the smaller the spot corresponds to the smaller the marking volume, therefore, the larger the spot, the faster the speed of marking.
2. marking format: because the large format marking galvanometer deflection area increased, so the large format marking speed than the small format marking speed is slower.
3. marking density: in the same format, the same spot, the same depth of the case, the higher the density of marking, the corresponding marking speed will be slower, the reason is that the density of the direct increase in the marking area.
4. marking depth: according to the demand, such as the need to deepen the depth of marking, the need for alumina fiber laser marking machine parameters are adjusted to increase the alumina fiber laser marking machine power, current and other factors, so in these processes will affect the marking speed.
Aluminum oxide marking black laser marking machine electro-optical conversion efficiency is high, the output beam quality is good, which is indisputable. But there are a small number of people in the marking, aluminum oxide marking out the black is not black enough, to white is not white enough and other issues, in fact, this is mainly due to the improper operation of the manpower caused by the Suntop laser has a group of professional and technical personnel, according to the customer samples to request proofing, customized to belong to the customer's own laser marking case.
