Nowadays, plastic has become the most commonly used packaging materials, we can often see on plastic products such as corporate trademarks, bar codes and numbers for identification marks. These marks are usually made by printing, embossing, punching, engraving and so on. The use of laser marking machine on the surface of plastic products for marking is a fast processing speed, can maintain the inherent surface characteristics of plastic products, so that the text or pattern and plastic into a unified whole of the advanced marking technology. So which laser marking machine is more suitable for marking on the surface of plastic products?
Different types of lasers emit different wavelengths of light and have different penetrating abilities. Therefore, marking machines equipped with different lasers differ in marking quality and marking speed. Fiber laser marking machine, UV laser marking machine and CO2 laser marking machine can all mark on plastic. But their application scope and effect are different, here are their specific application scenarios:
Fiber laser marking machine
Suitable for marking plastic materials with high ignition point in part (e.g. PC, ABS). As we all know, fiber laser marking machine mainly engraves and marks metal products, in fact, as long as the parameters are properly adjusted, fiber laser marking machine can also mark some plastic products. By choosing the appropriate parameters, the laser will only evaporate a thin layer of the plastic surface, and not burn the plastic itself. But even so, fiber laser marking machine is only suitable for partial marking of plastic products, if your workshop is only marking non-metallic materials or recommended to choose CO2 laser marking machine.
CO2 laser marking machine
CO2 laser marking machine is mainly suitable for acrylic and rubber. CO2 laser marking machine has good focusing ability as metal laser marking machine, so it is very suitable for fine marking of plastic products. Diode pumped solid-state laser has high beam quality, so that the laser beam during the marking process obtains a small focusing diameter. Currently, CO2 laser marking machines also have an irreplaceable role in plastics.
UV laser marking machine
Suitable for all plastic materials, mainly used in the high-end market of ultra-fine processing. Because the smaller line width of UV is 0.01mm, the marking accuracy of UV laser marking machine is better than other marking methods.
Advantages of laser marking plastic
When marking patterns on the surface of plastic products, laser marking machine has the advantages of low cost and high flexibility compared with traditional mechanical engraving, chemical etching, screen printing, ink printing and other methods. The laser marking machine can be controlled by a computer system, and it is very easy and convenient to complete the permanent engraving of the pattern to be marked on the surface of the material. The laser marking process does not require consumables, does not produce chemical pollution, and because it is non-contact marking, it does not damage the surface of the material, which is very safe and environmentally friendly.
Laser marking machines use laser beams to produce marks directly on the plastic surface, including marks, codes, text, numbers, patterns, lines, 2D codes, etc., and are marked in a single pass without the need for additional processing. ACCTEK laser marking machines can be used to permanently, quickly and with high quality to mark and process many different types of commercial plastics, such as polycarbonate, ABS, polyamide, etc. Due to the short set-up time and flexibility of the laser marking machine, it can be used for small-lot laser marking processes in the most economical way.
Laser marking machine marking plastic, the logo can be erased?
The patterns and numbers after laser marking are permanent and cannot be erased unless the surface layer is scraped away. So the use of laser marking machine marking product tracking code, two-dimensional code, brand logo and other information, can play a very good anti-counterfeiting effect.
