Laser marking machines are required to permanently mark, engrave, and anneal on metallic and non-metallic surfaces using the beam technology. The lasers use different beam emission technology, so they are categorized differently. Fiber lasers (fiber beam), Co2 lasers (Co2 gas tubal emission), UV lasers (UV beams), and Mopa lasers (beam pulses) are all examples of lasers. It includes aluminum, stainless steel, copper, plastics, wood, ceramics, stones, and many more.

How Does Laser Marking Work?
- Laser marking: Laser marking machines works on generating focused beams of light that contain high levels of energy. Once the laser beam hits metallic or non-metallic surfaces, it creates the designs as directed by the computer commands. The marks can be colored or black and white. Similarly, the laser marking machines do the below work:
- Laser engraving: Through this technique, beams can deeply put permanent marks over the metallic and non-metallic surfaces that can resist wear, tear, and friction.
- Laser etching: It creates high-contrast permanent marks over the material via the beam emissions at a high speed.
Benefits
- High-precision marking: It provides exceptionally high processing speeds and perfect marking.
- Cost & time efficient: A laser marker helps in mass production of complex marking, designing work in cost and time-efficient ways.
- Low power consumption: Irrespective of the laser marking material needs, it consumes comparatively less power consumption.
- Highly resistive laser marking: The permanent markings are highly resistant to acid, abrasion, and heat.
- Less Marking time: It is usually between 1~3 second over any compatible materials.
Application in Industries
- Electronics hardware tools
- Electrical instrument appliances, like switchboards, cables, etc.
- Aviation and spaceflight appliance markings and engravings
- Jewelry hallmarking
- Garments like shirts, jeans markings for logo designs, etc.

How to choose best laser marking machine?
Before moving ahead to choosing which marking machine is best fit for you. Here are the few points which you should look into consideration:
- Type of Identifier: For the marking needs on QR codes, 2D codes, data matrix codes, alphanumerical serial numbers, graphics, or logos, you must choose the best-fit technology for beam emissions.
- Readability Rate & Permanence: The marking machines work fine on the reading performances of barcodes or scanners. As well as the permanence also affects the machine’s performance.
- Durability and compactness: The machine has to be durable and compact so that it occupies less space and all the parts are durable.
- Available Marking & Cycle Time: You must analyze the available marking cycle time during its operations.
For Example:
Fiber lasers use ytterbium to generate photons. It has a 1,064 nm wavelength, thus it is ideal to mark metals.
CO2 lasers use a CO2 mixture via tubal emission. It has a wavelength range between (9,000 nm and 11,000 nm), thus being fit for organic materials.
