Plastic laser marking and printing, which is also referred to as plastic engraving, refers to the process through which plastic materials and components are marked with the help of a laser. The type of polymer that the plastic parts are made from the influence the methods to be used and the energy that is required to put the marks on the plastic.
The result of laser marking, to a large extent, depends on the type of plastic as well as the presence of additives such as dyes and the kind of laser used. Plastic laser marking an optical process that is non-contact and the plastic to be marked is made to absorb the laser beam. The same principle is utilized in plastic laser welding. In plastic laser welding, one of the welding partners absorbs the laser beam while the other is transparent.
Many thermoplastics and plastics are laser-printed and marked. If the properties of the plastic make it impossible to be laser marked, it can always be modified with an additive to make plastic laser marking possible. Some additives such as color pigments have also be known to influence laser marking capacity. Laser plastic marking and printing is advantageous in the following ways.
Plastic laser marking and printing are becoming popular in many industrial applications. This is because they are reliable, robust, of high quality and cannot easily be forged. Plastic laser marking and printing is permanent and cannot easily wear and tear. It is also heat resistant, resistant to chemical corrosion, and it is lightfast. They also have maximum flexibility in the printing and marking design and can be suited for areas that are difficult to access.
Plastic laser marking and printing are non-contact, and that means there are no wear and tear of tools. The cost of consumables that is common for the other forms of printing, such as inks and chemicals, are also non-existent in laser printing. This helps you to save a significant amount of money. The materials used for laser printing are free from tensions, pressure, and fixings, which means you can expect uniform and consistent results for multiple plastic laser printing processes. The plastic services to be marked also remain unimpaired, and the color does not change. The process is simple to handle, and pre or post-treatment is not necessary.
During the plastic laser printing and marking that is done through laser beam exposure, the material to be marked undergo some laser optical changes. Different laser media are used, and they bring out a huge difference in how the laser is generated. The process of plastic marking involves distinguishing the dye, gas, and solid-state lasers.
During the laser marking of plastics, the end results are affected by the wavelength of the laser in addition to the type of laser used. Solid-state lasers such as CO2 and fiber lasers are usually preferred because they bring out high-quality plastic markings. You should find a laser beam that works well with the type of plastics that needs to be marked.
