Laser Marking Plastic Products

Laser marking plastic products and components is a precise and sophisticated technique that necessitates a thorough comprehension of how different polymers interact with distinct wavelengths of the laser. While the majority of plastics can be marked using a laser, some may necessitate the inclusion of additives, such as titanium dioxide, to achieve a permanent and high-contrast mark. Our state-of-the-art laser applications lab boasts the capacity to test an extensive array of laser wavelengths, ensuring optimal results for any plastic marking endeavor.

Various laser marking methods exist, each offering unique advantages and outcomes when applied to plastic surfaces. Below are some of the most prevalent methods:

• Carbonization marking: Employing a high-power focused laser beam, this method induces a chemical change on the plastic’s surface, resulting in a dark, high-contrast mark that is both precise and durable.
• Foaming marking: This technique generates gas bubbles within the plastic material, creating a raised mark on the surface. It delivers an aesthetically appealing and distinctive mark, suitable for certain applications.
• Color change marking: Utilizing a low-power laser, this method alters the color of the plastic surface, yielding a contrasting mark that is well-suited for specific design and branding purposes.
• Engraving: By removing material from the plastic’s surface, this method produces a deep, permanent mark. It is particularly advantageous when a long-lasting and indelible mark is required.
• Annealing: This precise method involves heating the plastic surface to a temperature just below its melting point, causing a controlled color change that results in a permanent mark with minimal surface disruption.

Selecting the appropriate laser marking method depends on several factors, such as the type and color of the plastic, the desired mark quality and longevity, as well as the specific production requirements of the project. Each method has its merits and limitations, and our team of expert engineers at CMS Laser can guide you in making the best choice for your specific application.
