Latest Technology used in Laser Marking Machines
Laser marking of metals as well as other metallic items is among the most recent technological applications. This cutting-edge method of marking is being used successfully in a variety of industries to achieve the best outcomes in terms of quality and design. Our metal marking equipment is used in a variety of applications and use cases, including QR or Barcode branding, tools, and labels.
Due to its large applicable areas, the laser engraving machines are generally customised to Industrial needs, although Standard Specific based laser marking machines are more cost effective and quick to adopt, the Customization can attract additional costs and more time and energy to develop solutions for the Customer Use Case. Some engraver machines use a stationary workpiece and only move the laser (or inversely). Other machines are designed to work with cylindrical objects.
An advanced and more powerful laser source used in a Laser marking machine, provides a high quality and stable beam whose thickness can be measured in M2 units. The sharper the beam, the lower is the M2 value. Depending on the use case, customers can opt for various thickness and power of the beam. The beam, which is generated on the basis of use of Multiple pump diodes placed inside the laser source, is processed through a very sensitive Fibre inside the optic fibre of the laser source.
This laser beam is further modulated and optimised and processed through galvo mirrors present in Galvo scanners on the laser equipment. The high precision of movement of galvo mirrors guarantees very precise and micro marking accuracy in the laser marking machine. The focal length at which the laser beam excites heat and power is a very important spot from where the entire Peak energy is made to mark or cut the sample.
A very intuitive software which runs the whole system, has versatility to do numerous jobs including data marking, bar code or image marking, automated marking of serial numbers, date and time real time and many more applications are ready to use for customers who want to make the most out of the modern laser marking machines.
MANUFACTURING
Ink printing on a product or packaging typically results in messy, imperfect lettering or smearing in the manufacturing process, particularly if the object is moving while being imprinted.
Laser engraving solves this problem by being far more precise and able to generate even the tiniest text and symbols precisely as required by the operator. It solves many problems that cause identification issues and tracking issues in the Industrial environment. India is a growing market for laser equipment usage in many industries. Right from automobiles, to medical to steel to plastic. Laser machines cater an ocean of applications and industrial needs.
Since the last decade Laser equipment is revolutionising the Jewellery Industry. Due to the large segment of the jewellery industry moving into the transformation stage from traditional and unorganised to Organised and Industrial level, laser marking machines, laser soldering machines and laser cutting machines have become a big boon to this Creative industry.
Carbonising
Carbonising is the method of choice for marking organic materials and polymer blends. Heat from the laser causes plastic bonds to dissolve, releasing hydrogen and oxygen. The area darkens whenever this reaction occurs.
Carbonising may not always be ideal for dark-colored things since the mark generated is grey to blue-grey. As a result, there will be little difference between the indicated area and the remainder of the workpiece. Wood, paper, leather, packing material, and other materials are carbonised.
Foaming
Carbonizing isn’t very helpful when it comes to making light-colored marks. Foaming is more suited for such purposes. The laser is utilised to heat the surface of a substance in this process.
As a result of the material melting, gas bubbles are released. This foaming of oxidised gas bubbles reflects light. This strategy works best with dark-colored objects.
Staining
Whenever it comes to laser etching, the chemical structure of the substance can sometimes be leveraged to our benefit. Localised heating is caused by the laser beam. A chemical reaction is triggered by the heating. If the byproducts are a different colour, they provide such a lot of contrast wherever the laser hits the surface.
No puncture is required for staining. The mark’s appearance is determined by the thickness of the oxide layer.
Engraving by Laser
The laser beam eliminates some particles from the surface during engraving. This leaves a mark in the shape of depressions on the surface. This method works with a wide range of materials. Metals, plastics, stone, and ceramics are among examples.
CONCLUSION
The bottom line is that every modern firm should use cutting-edge technology to improve and streamline their manufacturing lines. Laser engraving is the youngest kid on the block, and it’s here to stay for the time being.
