Laser

shimimage3Laser processing technology is utilized for a wide range of industries, such as the motor vehicle, medical industries, mechanical, electronic and optical components and many more …
The reference is to instruments that emit controlled, coherent light, of light waves in a narrow spectrum and low diffraction – (Light Amplification by Stimulated Emission of Radiation).

Numerous applications exist for processing materials by means of a laser beam for a variety of industries, such as: laser marking, laser cutting, laser welding, removal of coatings by laser, ornamentation and so on.

The significant advantage of laser use is that the processing is performed without mechanical contact. Other than the energy radiated on the material, there is no mechanical friction and consequently attrition of the welding equipment is reduced. The absence of friction facilitates “freer” movement, enables freer and greater geometry of the item being processed. The laser beam is usually narrower than mechanical implements and facilitates microscopic applications..

Laser Cutting

A laser is utilized in this technology for cutting various materials. The procedure involves focusing a high capacity laser beam, by means of a computer, on the surface of the material intended for cutting. The material absorbs the laser’s energy and responds to an appropriate intensity by melting, evaporating or dispersing. The laser operates according to a focus distance, in other words, the distance between the lens and the material. Therefore laser cutting is particularly efficient in cutting flat panels (fixed distance from the lens). The thickness of the material that can be cut depends on the intensity of the laser beam, as well as the range of focus of the beam. The more the beam is focused the shorter the range of focus. Various types of laser exist at different wavelengths, suitable for diverse materials. For metals, for instance, a narrow wavelength (high frequency) laser beam is used, which ensures minimal energy dispersal. The concentrated energy succeeds in acting on the metal. For organic materials (wood, stone, leather, plastic), which do not disperse energy, wider wavelengths (lower frequency) can be used to cut efficiently.

Laser Welding

Utilization of a laser beam for welding is the perfect solution when an especially delicate and precise seam is required, or when the welded material must not be overheated.

Laser Marking

Laser marking is a unique procedure in which only the surface of the material is processed. Adjustment of the intensity enables marking a wide variety of materials and diverse shapes, such as: numbering items, company logos, scales (also circumferential) and so on.
