Knives and blades are involved in the production process of many materials such as paper, label production, packaging materials, flexible materials, films and so on. Like all other precision tools, cutting blades and knives have to be marked before being sold to manufacturers.
But how to mark cutting knives?
Laser markers are the perfect solution for marking on metal cutting tools, by a process of annealing the blade surface. The laser, however, must not etch or engrave the metal. The marking process must only be superficial with a color change so as not to damage the blade itself. Moreover, a perfect anneal marking is much more visible than engraving and will be permanent marking on the material.
Usually, cutting knives manufacturers will have the need to mark the name of the company, maybe a company or brand logo, a serial number, a part number or some information about the material and the product itself. Furthermore, the information marked on the blade surface can help the manufacturer to track the product on the market and for preventing not-original component or an improper use of the knife itself. Safety, handling and disposal information would also be such an application example for this type of marking.
How to chose the perfect marking laser
We usually do not suggest to use a fiber laser. Because of its more powerful laser beam output and marking characteristics that tend to engrave the metal easlier and may cause stress points or weaken the material. For metal blades and cutting knives Automator suggests to use YVO4 lasers or our aWaveTM proprietary technology laser marker. These marking systems can rapidly react to the part surface, without engraving or damage. Effectively causing the desired color change.
