How to use laser marking machine on the product hit the color? Nowadays, due to the increasingly advanced technology, laser marking machine in modern industrial applications increasingly plays an important role, we can see that most of the electronic products have been played laser tag. Especially in the food packaging, machinery and equipment, etc. is everywhere. Since there are so many industries have used laser marking machine, then the question arises: how laser marking machine is the color marking on products? Let Les laser technicians answer it for everyone. First, we need from the principle of laser marking machine to start, laser marking machine marked mainly by the laser focus instantly generate high-temperature gasification of surface material, usually play out are not the color. Playing out mainly to see the color of the material of the product itself. But playing in the stainless steel standard, laser marking machine has two modes, one is common marking, and the other is what we call "anti", by oxidation, resulting in a black mark effect. By setting different frequencies and marking speed and other parameters that can play different color effects, but it is quite difficult to adjust. Generally do not use laser marking machine to hit the color effect. Principle of oxidation generated using color, marking speed is not only slow, if different metal content within the material, play will be different colors. Color laser marking machine for marking items with high contrast color decorative effect, general color laser marking opportunities through the use of two laser marking needs to be carried out on plastic, metal and other materials. With the right laser output for marking substrates, to meet user needs in a variety of plastic and metal surfaces play in black and white or color imprinting with high contrast. Color laser marking machine with ink deposition technology applications as well as those by different colored powders or films that make plastic more advanced laser color change with the typical physical effects related to the thermal decomposition reaction of oxygen with the polymer occurs in the environment By contrast, in the metal surface can produce a variety of color materials. One is when the laser additive to be formed in the material fused into color and then play out there, there is a smudge on the surface of the material, color laser after fought to stay in the surface of the material, and now only play color with aluminum and ceramics This method, which uses a CO2 laser marking machine.
