Nowadays, due to the increasingly advanced technology, laser marking machine in modern industrial applications increasingly play a decisive role, we can see that the majority of electronic products have been played laser tag. Especially in the food packaging, machinery equipment, etc. is everywhere. Since there are so many industries have used laser marking machine, then the question arises: how laser marking machine marking colors in the product? Let Lesser laser technicians answer it for everyone.
First, we need from the principle of laser marking machine start, laser marking machine marked mainly by the laser focus will instantly generate high-temperature gasification of the material surface, generally play out it is not color. Playing out of color mainly depends on the material of the product itself.
But playing in the stainless steel standard, laser marking machine has two modes, one is ordinary marking, the other is that we say "anti", by oxidation, resulting in a black mark effect. By setting different frequencies and marking speed and other parameters, you can play a different color effect, but it is quite difficult to adjust. Generally do not use laser marking machine to fight color effect.
The principle of oxidation produced 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 goods with high contrast color decorative effect, general color laser marking opportunity by using two laser marking needs to be carried out on plastic, metal and other materials.
With the right laser output marking the substrate is to meet user needs in a variety of plastic and metal surfaces in black and white or color imprint shot with high contrast. Color laser marking machine with ink deposition techniques and those obtained by using color powder technology or film is different, more advanced lasers allow plastic color change with the typical physical effects related to the thermal decomposition reaction occurs with the polymer in an oxygen environment By contrast, in the surface of the metal material capable of generating a variety of colors.
One is when the laser additive to form in the material fused into color and then play out there, there is a smudge on the surface material, color laser fought to stay in the rear surface of the material, and now only playing colors with aluminum and ceramics This method, which uses a CO2 laser marking machine.
