Summary of laser marking machine marking plastic problems

Laser marking machine is a laser marking machine using fiber laser. The laser marking machine has the advantages of long service life, maintenance-free, no consumables, high stability, high production efficiency, wide application range, and low cost. At present, more and more industries are introducing and using laser marking machines. So how extensive is the application range of laser marking machines?

The materials marked by the laser marking machine are mainly metals and some non-metals. Its principle is to evaporate the surface layer of an object by laser to form a mark. For metal materials, most of them can be marked with a laser marking machine, but the effect is good or bad. For example, aluminum and copper can only be marked in white when marking on aluminum, and the marking is not clear. It takes a certain skill to make a clear marking on it. It’s good to be able to make a mark if it is copper. For plastics, hard plastics such as ABS are better for marking. There are many types of plastic materials. Generally, the harder, the darker the color, the easier it is to mark with a laser marking machine.

So can the laser marking machine mark plastic? The answer is yes. But there are conditions, some can be played, and those who do not meet the conditions cannot be played. Is it possible to mark different colors on the plastic? Generally speaking, the color of the laser marking machine is the color of the material itself. But like stainless steel, you can adjust the parameters to make the printed logo show a variety of colors. For plastics, generally only gray-black can be printed, and only the depth of the color can be adjusted, but other colors cannot be printed.

Will the laser marking machine burn the plastic when marking on the plastic?

The laser marking machine will not burn the plastic when marking on the plastic. The output power of the laser marking machine is generally not high. As long as the parameters are adjusted properly, the laser can only A thin layer of the plastic surface will evaporate without burning the plastic itself. So there is no need to worry about this issue. It is a laser cutting machine. Nowadays, it is difficult to use laser cutting machines to cut plastics in the industry without melting and yellowing. Of course, this is a digression.

Can the marking be wiped off when the laser marking machine marks plastic?

Generally not. Laser markings are generally sexual. Unless the surface layer is scraped off, it cannot be wiped off. Therefore, using a laser marking machine to mark the production date, the anti-counterfeiting mark is still very useful.
