Laser marking machine is applied to sanitary ceramic color marking

With the improvement of living standard, people more and more high to the requirement of material life level, the pursuit of personalized, ceramic laser marking machine high efficiency, good effect, such as ceramic sanitary ware, ceramic crafts, ceramic tableware products provides a good marking option.

The first, sanitary ware ceramic color marking on the process:
Due to the laser diffuse reflection happen on ceramic (close to the total reflection), ceramic of laser absorbent is very poor, so how to make ceramic absorption laser forming color tag?We take the train of thought is a layer of ceramic coating on ceramic coating, laser color marking on the ceramic is the result of high energy laser beam and the interaction of ceramic glaze, when the temperature reaches 800 ℃, and hair color laser ceramic carbon powder to infiltrate the ceramic glaze and glaze, color tag technology.At present there are two commonly used: laser coating and color paper, laser laser coating is color powder, its technological process is: first the powder and water mix, then evenly daub on ceramic surface, stay dry coating, with laser engraving.Laser color paper compared with laser coating operation is simple, convenient, and its technological process is: the laser color paper soaked in water, after falling off the laser color paper on the ceramic surface, about 5 minutes, instantly for laser engraving.

The second, the characteristics of the laser on the ceramic color tag:

1. using computer mapping, can make all kinds of text and graphics, fonts, specification, pattern formation is fast, and can be arbitrary processing.
2. is a great variety of ceramic sanitary ware industry, a variety of shapes and laser equipment can be used in a fiber optic transmission, make it portable, can work smart.
3. permanent marking, aesthetics, precision, no pollution, low cost, can greatly improve the grade of products!Can effectively improve product quality.

Why the optical fiber laser marking machine than semiconductor laser marking machine long life:

The service life of the semiconductor laser marking machine is twenty thousand hours, and the service life of optical fiber laser marking machine is 100000 hours, so the price of the semiconductor is much cheaper than fiber, because the price cheap, has caused many manufacturers choose semiconductor laser marking machine, at present is the most common metal industry laser marking equipment, with more and more research and development of domestic manufacturer of fiber laser technology is more and more mature, fiber laser marking machine price have been falling, probably in a few years of semiconductor laser marking the opportunity to be replaced by optical fiber.

Why there are such a big gap between them:

1. semiconductor laser tube core is very small, the working current density and power density is high, and as the material of semiconductor laser single crystal material is prone to defects, these defects under the action of electric and optical development gradually, causing degradation of device performance.
2. semiconductor laser marking machine laser mirror is formed by the cleavage process, the mirror itself is affected by environmental conditions and pollution can also lead to laser performance degradation.Pipe core welding is the key technology and core welding on heat sink, heat sink and active to distance are only a few microns;Semiconductor laser work can be fever, if too much solder and heat happens slowly climbing, short circuit in the semiconductor laser, laser degradation.
3. with the extension of working hours, the laser threshold current will increase slowly, resulting in the semiconductor laser marking machine, laser degradation.

Actually, the service life of semiconductor laser marking machine is not fixed, as long as we pay attention to maintenance at ordinary times, still can prolong the service life of it.In order to let your semiconductor laser marking machine is able to work longer, please you at ordinary times should pay attention to maintenance,the prospect of laser marking machine for sale is very good.
