LASER ENGRAVING IS EFFECTIVE FOR WHAT REASONS?

- Advertisement -

Laser engraving – what is it and what does it do?

Lasers leave permanent, deep marks in the material by vaporizing it into fumes. Laser beams act as chisels, making marks on materials as they remove layers. By striking localized regions with enormous energy, lasers create high temperatures that lead to vaporization.

The purpose of this article is to explain laser engraving in detail and to help readers choose a laser engraving machine.

Are laser engravings better than laser etchings?

There are three factors to consider when choosing laser marking:

  • Adaptable to harsh circumstances: able to cope with harsh circumstances
  • Production bottlenecks are prevented by laser marking speeds
  • It should be possible to mark the material with a method compatible with that material

Workpieces that are exposed to wear and surface treatment are typically engraved with laser technology. Aluminum and steel can be engraved with laser engraving machines (including anodized and diecast aluminum).

A high-readability 2D code is created with this process after post-processing. You can address traceability issues with shot blasting, electrocoating, and heat treatment.

Since laser etching is a high-speed, less ablation process, it is often preferred over engraving for highly resistant identifiers.

Solids are turned into gases by the process of gasification

With laser engraving, the surface of the material is sublimated, while laser etching melts the surface. Surfaces become gases without ever becoming liquids when they absorb enough energy.

Laser engraving systems producing sufficient energy must be able to reach the material’s vaporization temperature within milliseconds. Laser engravers can be quite powerful machines, given the high temperatures necessary for sublimation.

When these temperatures are reached, materials begin to vaporize. The surrounding environment and the lens should always be protected by fume extraction systems in laser systems. The price is often a factor considered by customers when buying laser engraving machines. 

Using fiber lasers to engrave metals is ideal because their wavelength is compatible with metals.

Selling laser engraving machines

From the following list you can find a laser engraving machine that meets your needs:

  • Additionally, we offer industrial lasers that you or an integrator can integrate with our OEM marking systems. Fiber lasers and CO2 lasers are both available.
  • Find turnkey laser solutions on our page for integrated laser machines.
  • The metal you will be marking can be found beneath the list of metals.
  • Experts are the best people to ask for advice when in doubt.

Is it possible to produce engravings with high contrast and quality?

There are deep crevices left by laser engraving, which appear darker (engraving depth can reach 0.5mm).

Laser engraving allows for two types of contrast.

A contrast is created between the bare surface of the material and the marks engraved there. The method shouldn’t be used unless the bare material has a pale enough color to produce high contrast.

 The second (and more elaborate) engraving method engraves both black and white marks, which gives it the appearance of having a higher level of contrast. The black marks are created by laser engraving and the white marks are created by laser etching.

Can laser engraving machines be purchased for a reasonable price?

Laser engraving machines are often chosen by customers based on price. 

You can find a CO2 laser, for instance, in small cutters or engraving machines sized 300x500mm for $2999*2400, 900x600mm for $3899*4699, and 1300x900mm for $3699*5399. Larger and more powerful lasers are more expensive, as are more powerful lasers.  If you need to engrave metal, fibre lasers are the best option. 

Fibre lasers are more efficient and easier to use than CO2 lasers to process thin metal materials, which is important for the creation of the metal product manufacturing industry. A 20W laser marking laser costs $2950, a 30W laser costs $3500, and a 50W laser costs $5500. Steel, stainless steel, and iron can be processed with a 20W laser;

For example, if you are looking to leave a deep mark on your jewellery, a laser of 30W or higher will do the trick; if you are looking for a delicate print, a 50W laser will do the trick. Please feel free to request a free sample test so that you may ensure that the machine you purchase meets your needs. During this test, you will receive information that will help you make the best choice.

It is more important to focus on what benefits and profits you will reap from laser engraving machines or fibre laser systems than on how much money you will spend. Maintaining the quality and efficiency of the machine is inextricably linked to maintenance costs and its added value, such as its longer lifespan.
