Functions and Application of Laser Marking Technique

Posted by John Smith on February 18th, 2019

The laser engraving or marking technique is used when a fast writing speed, great flexibility, and no force is exerted on the component. Other advantages are a short time needed and the great flexibility in the design of the characters, like stencils for lettering & designs. This technique can be used in stainless steel, steel, plastic, cast iron, and aluminum among other material.
 
Function description:
 
Thanks to the effect of the bundled light beam reflected by a deflecting mirror, the material is removed, paint is applied or foam is applied.
 
In the market, you can find many stainless steel panels engraved services that handle equipment, special equipment with automatic feeding of the workpiece and integrable devices according to the individual requirements of the client.
 
 Some applications of laser marking in metal:
 
Codes marking for product traceability and logos are one of the most used applications of engraving services.
 
These applications are found in many sectors like electricity and electronics, tool manufacturing, medical technology, signage, jewelry, automotive industry, metal plate processing, and mechanical engineering.
 
Laser marking techniques are also using in Name plate engraving.
 
Marked color in stainless steel:
 
Stainless steel has its particularity which can be marked with different colors. The particular type of laser allows markings in repeatable colors in stainless steel.
 
Engraving services offer the opportunity to create plates and differential products, special colors, such as a logo of the company or functional brands such as the indication of cold and heat in stainless steel facilities.
 
Tools for Printing:
 
The main tool used in this process is the steel stamps which are steel molds with cavities or internal holes called grooves, whose contours correspond to those of the piece to be made.
 
The stamps are made of high-quality carbon steels, being made those dedicated to making pieces of certain importance of alloy steels of high-quality tools. The stamp is made up of two parts: the upper part which is held in the mallet of the hammer, and the lower part, which is placed in the box for stamps.
 
In the cavity of the lower stamp, the blank to be transformed is placed which has been previously heated; by the effect of the blows of the upper stamp, the metal will fill all the holes of the stamp and the surplus excess is squeezed by a special notch to the effect. These burrs have from 15 to 20% of the total weight of the forged blank.
