Design & Manufacturing Considerations
Laser marking specifications should be confirmed during the early design stage to ensure marking location, size, and contrast meet both functional and regulatory requirements.
Permanent Product Marking Requirements
Determine the marking depth and processing method according to the operating environment, including high temperatures, chemicals, and wear conditions.
QR Code & Serial Number Traceability Planning
Verify the minimum QR code module size to ensure reliable readability across various scanning devices.
Logo & Brand Identity Design
Provide vector artwork (.AI / .DXF) to ensure accurate reproduction of engraved lines.
Anodized Surface Engraving Evaluation
Marking after anodizing produces high-contrast results. Sample verification is recommended to confirm color differences.
High-Contrast Marking Analysis
Select the optimal laser parameters based on the substrate color and surface condition to achieve the highest contrast.
