Laser Marking Process Parameters

For objective assessment of color changes a cie color difference formula delta e ab was.

Laser marking process parameters.

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. Altering this frequency creates different marking effects. The q switch is an electro optical system which controls the opacity of a lens making it possible to change the laser beam frequency.

Depending on the laser parameter settings certain materials can also be marked without damaging the surface. Yag green laser 532 nm. What materials can be marked with a laser. Pulse 5 ns to process the surface under normal atmospheric.

Laser etching process is used for marking those materials which cannot be marked by conventional machining processes. During the carbonizing process the. Yes there are a number of proven examples of laser marking transparent bottles in the beverage industry. 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.

This parameter is used to adjust the laser output frequency by directly operating the q switch. The color of marking is different than a mark produced by an inkjet printer. Depends on different materials and the marking effects you want so for a new operator may need conduct dozens of trials to know the ideal marking parameters for each material and even some experienced engineers. 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.

Laser marking is one of the fastest marking processes available in the market. In this work laser surface marking was performed on titanium substrate using doubled frequency pulsed nd. An additive is mixed into gabocom s pe pipes in order to ensure that the laser marking process generates high contrasts.
