Mingyu laser marking machine working principle detailed explanation

Release time:2024-08-24

Laser marking technology is an indispensable high-precision machining method in modern industry. As a well-known brand in the industry, Mingyu Laser marking machine is widely recognized for its efficient and accurate marking effect. Below, we will analyze the working principle of Mingyu laser marking machine in detail.

First, the basic principle of laser marking machine

Mingyu laser marking machine uses laser beams to mark the surface of a variety of different substances permanently. The marking effect is mainly achieved in two ways:

1. Hot working principle

① Mingyu laser marking machine uses high energy density laser beam, this concentrated energy flow irradiates on the surface of the processed material.
After the surface of the material absorbs the laser energy, a thermal excitation process is generated in the irradiated region, so that the temperature of the material surface (or coating) rises.
③ With the increase of temperature, the surface of the material will occur metamorphosis, melting, ablation, evaporation and other phenomena, so as to etch the required pattern and text.

2. Cold processing principle

Different from thermal processing, the cold processing principle of Mingyu laser marking machine relies on (ultraviolet) photons with a high load energy.
These high-energy photons can break the chemical bonds in the material (especially organic materials) or the surrounding medium, so that the material is destroyed by non-thermal process.
This cold processing method has special significance in laser marking processing, because it does not produce thermal ablation and avoids the side effect of "thermal damage".
The cold processing technology of Mingyu laser marking machine realizes the accurate processing of the surface to be processed by breaking the cold stripping method of chemical bonds, while not producing heating or thermal deformation.

2. Application examples

Taking the electronics industry as an example, Mingyu laser marking machines use excimer lasers to deposit thin films of chemical substances on substrate materials, or to open narrow grooves on semiconductor substrates. These applications fully demonstrate the excellent performance of Mingyu laser marking machines in the field of high-precision processing.

In short, Mingyu laser marking machine with its efficient, accurate marking effect and unique hot and cold processing principle, plays an important role in modern industry. Whether it is hot processing or cold processing, Mingyu laser marking machine can provide customers with satisfactory solutions.
