Guide for Laser marking technology

Laser marking technology is one of the biggest application fields of laser processing. Laser marking is a marking method that uses a high-energy-density laser to irradiate the part and make the surface material vaporize or change color. Laser marking can print a variety of characters, symbols, and patterns, character size can be from millimeters to microns, which has a special significance for anti-counterfeiting products.

The excimer laser is a new technology developed in recent years, especially for metal marking, which can achieve submicron marking. The strong and permanent nature of the marking produced by the laser action on the surface of the workpiece is its outstanding feature, so the laser marking system can apply a single identification number to the mass production workpiece, bAR code, or two-dimensional code array label on the product, can be very effective to help the implementation of production process control, quality control and to prevent counterfeit products, often used in the car engine to produce signs and trademarks. Laser marking does not contact the workpiece, the surface of the workpiece does not produce any mechanical deformation, and high-speed marking can be achieved by online real-time marking.

Methods/steps

Film Printing: in the polymer film printed on a variety of patterns;

Spray primer: many water transfer printing processing materials are coated with a layer of adhesive, if you want to transfer a different pattern, use a different ground color;
The extension of the membrane: so that the membrane is on the water level, and to be flat membrane stretch;
Activation: a special solvent (activator) to transfer the printing film pattern activation into the ink state;
Transfer printing: using water pressure, the pattern after the water transfer printing processing activation is printed on the substrate;
Water washing: will be printed on the remaining impurities of the workpiece washed with water;
Drying: the water transfer printing process is printed on the workpiece drying, temperature from the melting point of the material and the element of the point of view;
Spray Paint: spray transparent protective paint to protect the surface of the printed object;
Drying: to dry the surface of an object which has been sprayed with finish paint.
