Laser marking machine is a kind of laser machine which can achieve deep material through evaporation of surface material. Most of our daily necessities are processed by laser marking machine and get exquisite trademarks, patterns and words.
Laser marking machine
Because laser marking machine technology is becoming more and more superb, more and more exquisite workmanship, popular love. Demand for the market is also gradually expanding. This also makes many laser marking machine manufacturers more and more, but few high-quality laser marking machine manufacturers. So how can we find a high quality laser marking machine manufacturer?
I. Network Resources
There are abundant resources and information on the internet. No matter what products we can find, we can almost find the relevant manufacturers'information on them. For example, laser marking machine, which is used more frequently, there are not only a large number of manufacturers doing promotion on the internet, but also many professional forum platforms for manufacturers to promote and exchange. Therefore, if you want to know something about the manufacturer, you can search online directly, which is convenient and time-saving.
II. Offline Resources
Only after our own field investigation can we know the good and bad of laser marking machine. This is the dumbest way and the smartest way. And we are familiar with the principle of laser marking machine is better, it will not matter, I now give you popular science.
At present, there are two recognized principles of laser marking machine:
1. "Hot-working" laser beam with high energy density (it is a concentrated energy flow) irradiates on the surface of the material being processed, absorbs laser energy on the surface of the material, and generates thermal excitation process in the irradiation area, which causes the temperature of the material surface (or coating) to rise, resulting in the phenomena of metamorphosis, melting, ablation, evaporation and so on.
2. "Cold processing" has a very high load of energy (ultraviolet) photons, which can interrupt the chemical bonds in materials (especially organic materials) or surrounding media, so as to cause non-thermal process damage of materials. This kind of cold processing has special significance in laser marking because it does not produce thermal ablation, but does not produce "thermal damage" side effects and break the chemical bonds of cold stripping, so it does not produce heating or thermal deformation on the inner layer of the machined surface and adjacent areas. For example, excimer lasers are used in the electronics industry to deposit chemical thin films on substrates and to create narrow grooves on semiconductor substrates.
If you really want to start a laser marking machine, here we suggest you shop around three.
