Laser Marking




This can be achieved on materials that have some degree of carbon content within the metal. Black marks on tool steel, blue/black on titanium, green on cobalt etc. This style of marking is still permanent (material must be removed to alter the mark) but induces the least amount of stress, does not impinge of the material or create tissue capture regions for the medical instrumentation field.


The laser marking can penetrate through the coating to reveal the base metal. If this is not desirable, marking can be performed prior to plating and the end result is a subtle, uniform marking underneath the plating.


Depending on the requirement, laser marking can typically go .005″ deep and as much as .020″ deep. Self-diagnostic software monitors output power to the piece and will hold depths to within .0005″. Plated products such as anodize will give you a high contrast marking (silver or white in color) and still maintain its corrosive inhibiting properties.


Removing material in localized areas in lea of masking prior to plating. A typical application would be cutting circuit boards to complete an electrical series or parallel conductive circuit. In short, removing material under controlled conditions when stripping the entire material is not an option.


Constant heat and temperature cycles in an autoclave can adversely affect laser marking over time. Nitor has developed a process that does not break down during these cycles. This is a process that was developed with our medical partners.
