UV laser marking is a “cold” marking process, which means it minimises thermal stress on the target material. Instead of relying on heat, UV lasers photochemically alter the material’s surface, resulting in precise, high-resolution marks without melting or damaging delicate substrates. As industries drive deeper into miniaturisation and material innovation, UV laser marking becomes indispensable for achieving unmatched detail, traceability, and product integrity.
