Application of Mopa laser marking machine to marking black anodized aluminum
With the rapid development of my country’s aluminum products, electronics, machinery and other industries, the market’s demand for alumina continues to grow. Alumina uses metal or alloy parts as anodes and uses electrolysis to form oxide films on the surface. The metal oxide film changes the surface state and properties, such as surface coloring, improving corrosion resistance, enhancing wear resistance and hardness, and protecting metal surfaces.
In the production process, companies want to engrave LOGO trademark text and patterns on these alumina products. How did these words or patterns get on? In fact, it is formed by laser marking processing.
The Triumph laser marking machine is fast and efficient in aluminum marking, and the patterns are clear and exquisite. So it is very popular. Like Apple mobile phone shell, keyboard markings, lighting industry and so on.
Anodized aluminum is used in many industries. Because of the uniqueness of aluminum oxide, ordinary lasers cannot produce black color. Aluminum can be painted gray or black-grey, but it can’t be blacker. Copper can’t be too black either. It’s good to be clear. This is also its special feature.
In fact, it is a special fiber laser marking machine that can really mark alumina into black. Our name is Triumph Mopa fiber laser marking machine. It adopts fiber laser to output laser, high electro-optical conversion rate, small size and good beam quality. It can perform shallow blackening effect on aluminum alloy (aluminum oxide, anodized aluminum) to achieve visual effects and durability. Triumph Mopa fiber laser marking machine can make black logos, text patterns, etc. on the surface of various colors of anodized aluminum.
The aluminum oxide black laser marking machine is different from the ordinary fiber laser marking machine. This laser marking machine adopts the pulse width adjustable mode, and the frequency can be adjusted up to 400Khz, which can directly mark the aluminum material with a black effect. Aluminum, aluminum oxide, and various aluminum materials are common. The small characters on the iPhone shells or ipad shells on the market are all made with this fiber laser marking machine.
Triumph Mopa fiber laser marking machine for anodized aluminum laser marking principle is based on the quality of oxidation, that is, the thickness of the oxide film directly determines the effect and efficiency of blackening. Generally, it is easier to blacken when the film thickness is 10-20um. When the film thickness is less than 8um, the oxide film is too thin, easy to break, and white spots appear. It is necessary to increase the pulse frequency and increase the filling density.
In addition, the anodized aluminum surface treatment process will directly affect the blackening effect. Sandblasting and surface drawing are common processes. The thickness of the sandblasting will have different effects on the marking effect. The finer the sandblasting particles, the better the blackening effect. . It is recommended that the film thickness of anodized aluminum be 10-15μm, so that the overall blackness effect will be better.
Black anodized aluminum laser marking machine can choose Triumph Mopa fiber laser marking machine. Triumph Mopa fiber laser marking machine can realize the effects of deep engraving, light engraving, black engraving and white engraving on alumina, as well as engraving LOGO trademark, text, two-dimensional code, pattern, serial number on aluminum products , Serial number, symbol.
Triumph Mopa fiber laser marking machine has fast engraving speed, high production efficiency, long service life, simple operation, zero consumables, and free modification of patterns and text. Triumph laser has a group of professional technical team and after-sales service team, which can provide customers with free proofing, remote technical guidance and other services.
