Laser Marking Process Parameters

The color of marking is different than a mark produced by an inkjet printer.
Laser marking process parameters. For objective assessment of color changes a cie color difference formula delta e ab was. The investigations were performed using a commercially available industrial pulsed fiber laser. What materials can be marked with a laser. An additive is mixed into gabocom s pe pipes in order to ensure that the laser marking process generates high contrasts.
Laser marking is one of the fastest marking processes available in the market. During the carbonizing process the. This parameter is used to adjust the laser output frequency by directly operating the q switch. The aim of the current study attempts to investigate the effects of laser etching parameters specially the scanning speed ns peak power kw frequency khz and heat input j mm 2 on the corrosion resistance and variations in surface roughness properties of the marine.
This is an application that is often used to print the time of manufacturing and the expiration date on the product. In marking metal and plastic there is a setting parameter range for reference to test speed 100 2000 adjustable power 30 80 adjustable frequency 5 30. Depending on the laser parameter settings certain materials can also be marked without damaging the surface. In this work laser surface marking was performed on titanium substrate using doubled frequency pulsed nd.
Plastics which as a result of a laser marking process show no contrast in the pre doping phase display a legible inscription after the additive has been added. Altering this frequency creates different marking effects. Laser etching process is used for marking those materials which cannot be marked by conventional machining processes. Pulse 5 ns to process the surface under normal atmospheric.
The q switch is an electro optical system which controls the opacity of a lens making it possible to change the laser beam frequency. This paper presents the results of the measurement and analyses of how the laser marking process parameters influence the colors created on titanium. This results in high productivity and cost benefits during manufacture.
