What is UV Laser Engraving Machine
UV laser engraving machines are designed to create permanent markings on materials with minimal heat damage. This is due to the high absorption rate of UV light, which protects the material surface from damage and enables corrosion-resistant marking. They are faster, more accurate, and more versatile, and they can create complex and intricate designs with ease. Its ability to produce clean and permanent marks makes it a preferred choice for applications requiring fine detail and high contrast.
Advantages of UV Laser Engraving Machine
● High absorption rate
A UV laser has a 355 nm laser with an incredibly high absorption rate. This means that even with materials that have high melting points, like glass or metal, the UV laser can still mark them without using high power. Additionally, since the absorption rate is so high, the laser does not damage the material.
● Long-lasting results
The marks produced by UV laser engraving machines are permanent and can withstand harsh environmental conditions, such as exposure to water, chemicals, and heat. UV laser engraving machines can mark on a wide range of materials, including plastics, metals, glass, ceramics, and more.
● High-contrast markings
UV laser engraving machines can produce high-contrast markings that are easily visible, even on dark or transparent materials. UV laser engraving machines can create intricate designs with high accuracy, making them ideal for applications that require detailed markings.
● Non-contact process
The laser engraving process is non-contact, which means that there is no physical contact between the machine and the material being marked. UV laser engraving machines can operate at high speeds, making them ideal for applications that require quick turnaround times.
● Cost-effective
UV laser engraving machines can reduce production costs by eliminating the need for additional materials, such as ink or labels, and by increasing production efficiency. UV laser engraving machines require minimal maintenance and have a long lifespan, which makes them a cost-effective solution in the long run.
● Safe operation
UV laser engraving machines have safety features that prevent accidental exposure to the laser beam, making them safe for operators to use. UV laser engraving machines use a non-toxic marking process that does not produce any harmful by-products, making them an eco-friendly option.
Working Principle of UV Laser Engraving Machine
The processing of UV laser engraving machine is called the light etching effect. "Cold processing" has (ultraviolet) photons with high load energy, which can break the chemical bonds in the material OT the surrounding medium, so that the material is destroyed by a non-thermal process. No heating or thermal deformation, etc. of layers and adjacent areas, resulting in a material with smooth edges and minimal carbonization. The fineness and thermal impact are minimal, representing a significant advancement in laser technology.
The reaction mechanism of UV laser engraving processing is realized by photochemical ablation, that is, which relies on laser technology to break the bonds between atoms or molecules, making them gasify and evaporate into small molecules. The focusing spot is small, and the processing heat-affected zone is very small, so it can be used for ultra-fine marking and special material marking.
How Does a UV Laser Engraving Machine Work?
he mechanism of the UV laser engraving machine is quite simple. The machine first reduces the wavelength of a 1064 nm laser to 532 nm by passing it through a non-linear crystal. The laser is then run through a second crystal to shorten its wavelength to 355 nm. This technology of reducing wavelength is known as a three-stage intracavity doubling frequency. The main mechanism of the machine begins when these UV rays with a short wavelength of 355 nm are projected onto the materials.
The 355 nm UV beams contain high-energy photons. When these photons are projected on the materials, the surface of the materials experiences non-thermal damage, resulting in the breaking of their chemical bonds. The UV laser engraving process is also known as cold processing since a negligible amount of heat is produced during the process. As a result, the surrounding area and inner layer remain unaffected, and only the surface area where the light falls is processed.
