CONSEQUENCES OF LASER MARKER AND ITS BENEFITS

A laser marker is for marking all kinds of information such as characters such as dates and serial numbers, 2D codes, logos, etc. by irradiating an object with laser light and changing the state by oxidizing, peeling, coloring, etc. on the surface. It is a device. Laser markers have different materials and applications suitable for printing and processing depending on the wavelength of the laser light.Marcatrice laser prezzo used for marking include YVO4 lasers, fiber lasers, UV lasers, and CO2 lasers.

In contrast to marking with a stamping machine or etching, marking with a laser marker can be stamped without touching the object, so there is no burden on the product. In addition, high-visibility printing can be performed at high speed not only on flat surfaces but also on uneven surfaces and curved surfaces, and small printing of 1 mm or less is also possible. In addition, since the print contents can be easily changed, it is possible to print on a wide variety of products.

Benefits of laser markers

Advantages of laser markers 1: Printing that does not disappear semi-permanently

Since the laser marker prints with light, it is possible to print semi-permanently.

Since the material of the product itself is reacted with laser light to develop color and engrave, there is no risk of the print peeling off or coming off.

It is used not only for tracking products on the market but also for a wide range of traceability applications such as history management in the manufacturing process.

Laser marker advantage 2: No maintenance work required

Laser marking is a method of printing by irradiating the product with laser light, eliminating the need for daily maintenance work such as replacement of consumables and cleaning of the print head, which were required with the conventional ink and label methods.

Advantages of laser markers 3: Printing is possible even on three-dimensional shapes

Laser marking enables clear printing not only on flat surfaces but also on three-dimensional shapes.The laser beam can be freely scanned in the area, and not only character strings but also all kinds of information such as 2D codes and logo design printing can be printed.In addition, it also supports microfabrication such as surface roughening, cutting, and drilling.

The hybrid laser marker is equipped with a newly developed laser oscillator that combines the advantages of both high-quality printing of YVO4 laser and high-speed printing of fiber laser. Ideal for printing on metals, resins, ceramics, etc., and for microfabrication. In addition, the distance measuring sensor and multifunction camera mounted inside the laser head can automatically correct the deviation of the focal point of the laser beam and the deviation of the printing position. Prevents printing defects and realizes stable operation.

The best-in-class output of 50W and 3D control are combined to significantly reduce printing / processing time and setup change man-hours. It is a laser marker that meets the needs of high-power laser printing to shorten the printing tact and to engrave deeper. Furthermore, the stable operation performance of the laser marker has been enhanced by incorporating an environment-resistant compact fanless head thermopile type power monitor. It continues to demonstrate high printing and processing capabilities and contributes to productivity improvement.

The UV laser (wavelength 355㎚) is converted from the basic wavelength laser (1,064㎚) to 1/3 wavelength. Since the UV laser has a significantly improved light absorption rate for each material, it achieves high quality in materials that did not develop color well with conventional laser markers and in applications where there is concern about damage to printed and processed parts. In addition, the laser marker head is equipped with a multifunctional camera that can check prints and read 2D codes. One-stop printing and reading.

Equipped with a telecentric lens in which the laser light is vertically incident in the entire area, a uniform spot shape of the laser light is realized at both the center and the edges of the area. It enables uniform printing and processing quality in all areas. In addition, the φ20㎛ green laser realizes a very small character that suppresses damage in printing and a sharp cut that suppresses excess heat in processing. In addition, by adopting an ultra-rigid monocoque body, we will continue to maintain stable printing and processing quality even in applications that require high accuracy.

The CO2 laser can print on transparent materials such as glass, as well as paper, wood, rubber, and ceramics. It is also used for processing such as gate cutting, drilling, and film peeling. The 3D control function not only allows printing on three-dimensional shapes such as cylinders, slopes, and steps, but also simplifies setup changes to products of different sizes. In addition, the wide area type of 300 x 300 mm enables efficient printing and processing on products at once, reducing equipment costs.
