Whether your next laser etching product is an art product or an industrial product, choosing the best laser pointer machine that can meet your needs is the first step to success.
This physical process changes the properties and/or appearance of the material. Material modification is used for laser marking on the material surface by changing the appearance or properties of the material.
The terms laser engraver cutting, laser engraving and laser marking are commonly referred to as laser processing. Depending on the compatibility of the materials, a single laser process or a combination of multiple processes can be applied to the material.Cold processing + precision processing UV laser has unique characteristics, which is called “cold” processing. Lasers with shorter wavelengths and pulse widths and lower M2 (beam quality) can produce a more concentrated spot and maintain the smallest heat affected zone (HAZ). In marking applications, it can retain objects to the greatest extent and reduce damage during processing. For example, glass marking, ceramic carving, glass perforation, flexible circuit board cutting, etc., are very popular among processing companies.
Ultraviolet rays are invisible to the naked eye. It has small spots (0.07mm), narrow pulse width, fast speed and high peak output. High-energy blue laser pointer is used to irradiate the workpiece locally to evaporate surface material or change color. The photochemical reaction leaves a permanent mark. High power, high pulse repetition frequency (PRF), pulse shaping and pulse splitting can all help improve the productivity of micromachining.
When viewing marketing materials, please pay attention to the following keywords: powerful, bright, super, super, military grade, powerful, blasting, burning, burning, adjustable focus, lithium battery and lithium power.Eye injuries caused by lasers are usually not injured. Therefore, it is better than regretting, to be safe and not to let all laser pointers close to the eyes.
Laser etching is faster, but laser engraving is more durable. This is because reaching a material’s melting point (laser etching) requires less energy than vaporizing it (laser engraving). Deep laser engraving may even require several laser passes and inevitably even more time.
Laser etching stands out when it comes to creating high-contrast markings. Whereas laser engraving only creates black marks, laser etching can be used to create both black and white marks. For this reason, laser engraving is usually used in combination with laser etching to create high-contrast engravings.On the other hand, the holes dug with engraving have a better protection against abrasion than the elevated marks formed with etching. In fact, the laser etching elevation can reach up to 80 microns whereas the laser engraving depth can reach 500 microns.
