Laser Marking

Laser Marking, also called laser engraving, uses high frequency ray to treat surfaces. A laser beam can be used to engrave a permanent mark into a transparent surface. We often purchase watches, bracelets, and other metal items that have lettering done on them; these products typically use radium carving, which has a respectably high efficiency. It has texture and can be preserved for a very long time.

Laser Marking is the most popular industrial application for which scan systems transform lasers into useful tools. Due to scan systems' dynamic performance, precision, and speed, as well as the cost-effectiveness they have achieved, there are numerous marking applications.

Lasers can be used to mark a variety of materials, including paper, metal, and plastic. The markings are extremely durable, waterproof, and smudges, solvents, and abrasion-resistant. Additionally, Laser Marking offers remarkable design flexibility because no molds or stencils are required. The process is also wear-free and contactless.

Owing to their unique characteristics, scan systems are perfectly suited for numerous Laser Marking applications.

Applications for Laser Marking

Laser marking technology is growing in popularity and has a wide future, applied by many different sectors including electronics, automotive, healthcare, and aerospace.

Consumer Electronic

Laser marking technology is frequently utilized in the processing of casing, keyboard, touch pad, camera protective cover, and other components for products like smart phones and tablets.

Medical Industry

Manufacturing of medical equipment, medical containers, biochips, and other items can be done using laser marking technology.

Automotive Industry

Automotive interior components, such as instrument panels, door panels, etc., can be produced using laser marking technology, enhancing and personalizing the inside of the vehicle. Nowadays unique identity is required in automotive industry by IATF 16949. Laser marking is a rather good method for indentifying each plastic part.

Aerospace

Solar panels and other products may be made using laser marking technology.

The Advantages of Laser Marking

In part of a procedure known as plastic engraving or Laser Marking, plastic parts and components can be engraved or identified using a laser. The plastic must absorb the laser beam 34–36 in the non-contact optical process known as Laser Marking. Many thermoplastics and polymers have the option of Laser Marking. The results of the Laser Marking depend on the kind of plastic being used, any additives present in the plastic, and the kind of laser being used. The advantages of Laser Marking include the following:

A long-lasting, consistent and dependable procedure.
Highly adaptable design for markings of various dimensions and forms.
Programmable software allows for quick design changes and the generation of 2D and 3D marks.
Precise arrangement of marks and letters, particularly on curved or uneven surfaces.
Photos with exceptional clarity, precision, and resolution.
Waterproof, wear-resistant, heat-resistant, light-fast, chemical-resistant, permanent, indelible marking.
The capacity to endure repeated sterilization.
Meet the UDI requirements.

Differences Between Fiber Laser and
CO2 Laser

Various types of lasers emit different wavelengths depending on their gain medium(one component of the laser source). The material you will be marking will determine which type of laser marking system you need.

Fiber laser system

Fiber laser system is the best method for marking metals. Fiber laser systems are sometimes treated as solid-state lasers. They have a laser source that contains an optical fiber which includes a rare earth metal such as ytterbium. They generate laser light with a wavelength of about 1 micron (1064 nanometers). Most metals respond well to fiber laser marking.

CO2 laser system

CO2 laser system is the best method for marking organic materials. The CO2 laser system has a laser source containing gas. It is also known as gas-state laser system. The CO2 laser system can produce lasers with wavelengths ranging from 9 microns to 10.2 microns (9000-12,000 nanometers). Most organic compounds respond well to these wavelengths. But in contrast to fiber laser systems, metals respond poorly to these wavelengths.

The quality of the laser mark depends on the type of material.

Plastic type

Black ABS material, black ABS radium carving white font, and black ABS radium carving gold font are the most popular ABS radium carving materials on the market.

Part thickness

The effect of laser marking is influenced by the thickness of the components; if the parts are too thin, harm can be easily done.

Additive type and level

A good additive may enhance the ability of plastics to absorb laser energy, produce characters engraved in radium that are clear, and increase the speed and effectiveness of radium engraving when engraving plastic with a laser.

Laser type

The distinction between laser engraving machines is primarily made by the lasers, UV laser engraving machines, 3D laser marking machines, semiconductor laser engraving machines, and other various laser engraving machines in different materials of the object to play the effect is different, such as depth, speed, color, thickness, and so on.

Wavelength of the laser beam

If the laser beam wavelength is too short, it won't be able to reach the workpiece's surface, leaving the marking incomplete. Otherwise, it will have a heat effect on the waste materials and other parts of the workpiece. As a result, while processing, we must be careful to choose laser beam wavelength that is appropriate for our own processing goods.
