Laser marking has become a cornerstone of modern manufacturing, offering unparalleled precision and durability for marking plastics. However, achieving clear, high-contrast marks on certain plastics can be challenging without the right tools. This is where laser marking additives come in, enhancing the marking process for a wide range of applications. In this blog, we’ll explore how to use laser marking additives effectively, which plastic materials require them, and spotlight industry expertise from leaders like DOME Materials.
What Are Laser Marking Additives?
Laser marking additives, or laser-sensitive additives, are specialized compounds mixed into plastic substrates to improve the visibility and quality of laser marks. These additives enhance the material’s response to laser energy, enabling crisp, high-contrast markings without compromising the material’s integrity. They are particularly useful for plastics that are difficult to mark, such as those with dark pigments or high filler content.
How to Use Laser Marking Additives
Using laser marking additives is straightforward but requires attention to detail to achieve optimal results. Here’s a step-by-step guide:
- Select the Right Additive: Choose an additive compatible with your plastic substrate and laser system (e.g., CO2, fiber, or UV lasers). Consult with manufacturers like DOMEMaterials, who offer tailored solutions for specific polymers and marking requirements.
- Mix the Additive with the Substrate: Incorporate the additive during the injection molding or pelletizing process. Ensure even distribution by thoroughly blending the additive with the plastic pellets. Typical additive concentrations range from 0.5% to 3%, depending on the material and desired marking effect.
- Prepare the Raw Materials: Use natural or transparent raw materials for best results, especially when aiming for black or gold markings on dark polymers. Avoid carbon black or black masterbatch, as these can interfere with the laser’s ability to create contrast.
- Dry the Materials: Before mixing, dry the raw materials to remove moisture, which can affect the molding process. No baking is required for the additive itself—just ensure the pellets are dry and ready for processing.
- Test the Laser Settings: Conduct a small-scale test to fine-tune laser parameters (e.g., power, speed, and frequency). This ensures the additive responds as expected and produces clear, precise marks without damaging the material.
- Follow Manufacturer Guidelines: Always adhere to the additive manufacturer’s instructions for dosage, mixing, and processing. Proper handling and disposal of materials are also critical for safety and environmental compliance.
By following these steps, you can achieve consistent, high-quality markings that enhance both aesthetics and functionality.
