Cold Laser Marking is an advanced laser engraving method that utilizes ultra-short laser pulses to mark materials without generating significant heat. This “cold” process is essential for applications that require high precision, minimal surface damage, and no thermal distortion—especially in plastics, electronics, and medical devices.
Cold laser marking, also called cold ablation, uses femtosecond or picosecond laser pulses to remove material or alter the surface without thermal side effects. Unlike traditional laser marking systems that rely on heat, cold lasers vaporize the material at the molecular level before it heats up, resulting in precise, clean marks with no burning, melting, or discoloration.
Marks surgical tools, implants, and catheters without altering structural integrity or biocompatibility. Often used for UDI compliance.
Used for PCB coding, semiconductor wafer marking, and high-density data applications without short circuits or material damage.
Enables high-contrast marking on plastics like polycarbonate and polyimide, which are sensitive to heat.
Cold laser engraving creates intricate, permanent marks on tiny components without deformation or scratches.
Cold lasers are compatible with a wide range of materials, including:
Unlike thermal laser systems, cold laser marking uses ultra-short pulses (femtoseconds/picoseconds) that remove material faster than heat can spread, eliminating burn zones.
It depends on the application. Cold laser marking is superior when working with delicate, heat-sensitive, or micro-scale parts where thermal damage would be unacceptable.
Typically, femtosecond lasers and picosecond lasers are used. These ultrafast lasers offer incredibly short pulses and high peak power for precision ablation.
Yes, it’s ideal for plastics that are prone to melting or discoloration under heat. It allows sharp contrast marking on materials like PI, PC, and ABS.
Yes, the marks created are permanent, abrasion-resistant, and unaffected by moisture, chemicals, or UV exposure.
Cold laser marking offers a powerful solution for industries requiring ultra-precise, damage-free, and permanent marking. By eliminating the risks of thermal distortion, this method is especially suited for cutting-edge applications in electronics, medical manufacturing, and advanced plastics.
