![]() ![]() ![]() The wavelength of the laser plays an important role in marking plastic. During plastic processing, the result is influenced not only by the type of laser but also by the wavelength used. For this purpose, a variety of laser supports are used, which differ in the way the beam is generated. Types of lasers usedDuring laser marking, plastics undergo optical surface changes through exposure to the aforementioned beam. Thanks to the short set-up times of the laser machine and the flexibility offered, even small batches can be marked economically.Processing is simple and no pre-treatment or post-processing is required.The processed plastic is always free from pressures, tensions and fixings, in order to guarantee consistently uniform results.There is no tool wear and no additional cost for extra materials such as chemicals, inks, etc.The whole process takes place without any contact with the material.Maximum flexibility in the design of the marking, so it is also suitable for areas usually difficult to access.Laser marking is an extremely effective, high quality and forgery-proof process.The marking is permanent, as it is waterproof, resistant to wear and heat, light and chemicals.The absorption by the macromolecular structure of the plastic is usually in the ultraviolet and infrared range.įor further information read -> Why UV Lasers are used: applications, characteristics and types The advantages of Laser Marking on PlasticProcedures such as laser marking and engraving are used more and more frequently in the industrial field as they are considered particularly reliable and also offer numerous advantages over conventional marking technologies: The low thermal conductivity of the plastic means that the energy loss during laser marking is low, so processing is very fast. Metals tend to reflect most of the ray, while in plastic the reflection is widespread and absorption is very high. The key in the plastic laser engraving process is to achieve sufficient absorption of the laser beam into the material. Additives such as color pigments can also affect laser marking ability. By masterbatch we mean a concentrated mixture of pigments and / or additives encapsulated during a thermal process in a support resin which is then cooled and cut into a granular form. If a plastic cannot be laser marked, it can usually be processed with an additive or masterbatch suitable for laser marking plastic. Many different types of plastics and thermoplastics can be laser marked. This typical behavior is also exploited in the laser welding of plastics, a process during which one welding joint absorbs the beam while the other welding joint is transparent to the laser. Laser marking is an optical process in which plastic absorbs the laser beam without having any contact with it. The result of laser marking depends on both the type of plastic and the additives used such as dyes and the type of laser used. The polymer of which the plastic parts are made determines the method used and also the amount of energy needed to carry out the laser engraving of the plastic. Delrin, Teflon, PEEK, Ceramic and ABS are examples of medical plastics that are commonly marked by the plastics engraving process.Laser marking on plastic or laser engraving on plastic is a process by which components are labeled or marked with the aid of a laser. Laser marking plastic can produce a dark, smooth mark on most surfaces so the laser marking does not trap blood or tissue material and thus simplifies cleaning and sterilization. The medical engraving process is approved by the FDA, so instrument and component manufacturers have one less hurdle in the product approval process. Now that plastic is common in the doctor’s office, manufacturers of medical devices have found that laser engraving medical devices offers many benefits such as mark clarity, permanency (no added paints or chemicals), and its ability to survive repeated sterilization. Laser Marking Plastic for Medical Devices Our clients use the precise, laser engraving process for bar codes, 2d codes and part serialization in both large and small lot runs.
