Laser Marker for Polyamide Strip Identification | POLYWELL

A laser marker engrave printing machine is an advanced manufacturing tool that uses a focused laser beam to permanently mark, engrave, or etch surfaces with high precision and speed. Unlike traditional printing methods like inkjet, which apply a substance to the surface, laser marking is a non-contact, non-abrasive process that alters the surface properties of the material itself. Common laser technologies include fiber lasers, ideal for metals and some plastics, and CO2 lasers, better suited for organic materials like wood, glass, and many polymers. The process is controlled by computer software (CAD/CAM), which directs the laser beam to create text (such as serial numbers, date codes), 1D/2D barcodes (like Data Matrix or QR codes), logos, or other graphics. The marking mechanism can vary: for plastics, it often involves foaming (creating a light mark), carbonization (creating a dark mark), or color change through a chemical reaction. The key advantages of this technology are its permanence and resilience; the marks are resistant to fading, abrasion, and heat, ensuring traceability throughout a product's lifecycle. It is also an extremely clean and eco-friendly process, requiring no consumable inks or solvents. In an industrial setting, such as a profile extrusion line, a laser marker can be integrated to directly mark product information onto the plastic profile at line speed. This allows for unparalleled traceability, quality control, and customization, meeting stringent industry requirements for part identification in sectors like automotive, aerospace, and construction, where durable, high-contrast markings on components like thermal break strips are essential.
