Plastic is a material that can be laser marked with the appropriate laser system and settings. Laser marking on plastic is a versatile process used for a variety of applications such as product branding, serial numbers, barcodes, logos, decorative designs, and more. The process of laser marking on plastic involves using a laser beam to create a permanent mark on the plastic’s surface.
However, not all types of plastic are equally suitable for laser marking, and the results can vary based on factors such as the type of plastic, its composition, color, and additives. Here are some common types of plastics that can be laser marked:
Acrylic (PMMA): Acrylic is a popular plastic for laser marking due to its consistent and high-quality results. Laser marking on acrylic can produce clear, precise marks with high contrast.
ABS (Acrylonitrile Butadiene Styrene): ABS plastics can be laser marked, but the results can vary based on color and composition. Dark-colored ABS tends to provide better contrast.
Polypropylene (PP): Laser marking on polypropylene is possible, although the contrast might not be as high as with other plastics. Some additives can improve marking quality.
Polycarbonate (PC): Polycarbonate can be laser marked with good results. It’s often used for industrial applications requiring durability.
Polyethylene (PE): Marking on polyethylene can be more challenging due to its low energy absorption, but some formulations can be successfully marked.
Polyethylene Terephthalate (PET): PET plastics can be laser marked with suitable settings, producing varying degrees of contrast depending on the color.
Polyvinyl Chloride (PVC): PVC can be laser marked, but caution is needed due to the release of chlorine gas during the process.
It’s important to note that different types of plastics have varying responses to laser marking, and factors such as color, additives, and surface texture can affect the quality and contrast of the mark. Laser marking systems that provide control over parameters like laser power, marking speed, and frequency can help optimize results for different plastic materials.
Before laser marking any plastic material, it’s advisable to consult with laser marking experts, test on sample pieces, and optimize the laser settings to achieve the desired results while ensuring that the material remains structurally sound.
