The development trend of laser cutter template

Laser die-cutting version in recent years, with the continuous improvement of people's living standard in our country, the demand for goods is not only stay on the practical level, to the appearance of the commodity packing also put forward higher requirements, especially for display, gift bag is more and more picky. Parts of printing and packaging industry was rapidly, so have the introduction of foreign cooperative joint venture, some enterprises are also a large number of imported famous brand gravure and flexo mechanical equipment, at the same time, also introduced a lot of international famous brand die-cutting machine, such as Bosch, Switzerland, Japan's xu iron brands. But the die cutting plate processing industry in China packaging industry development is relatively backward, handmade die cutting version is still in some enterprise applications. Manual die-cutting version of quality affected by man-made factors, for the high requirements of die cutting version or curve of die cutting plate can't meet the requirements. Now, especially the application of advanced die-cutting machine, more and more high to the requirement of die cutting plate, manual die cutting have been struggling, and laser die cutting version of the application is more and more widely. The following from various aspects about laser die cutting plate. A, 1, laser laser cutting principle characteristics make it widely used: a high brightness: the brightness values of gas laser of 108 w/cm2ooSr. After lens, near the focal point is to thousands or even tens of thousands of degrees of high temperature, almost can processing all of the materials. B high directivity: laser beam divergence Angle is small, so can guarantee gathered to get high power density. C high monochromaticity: the output of the laser frequency stabilization monochromaticity Δ gamma/Δ lambda can reach 10 - 1010 - 13 orders of magnitude. D high coherence: is the spatial distribution character of the optical field depends on the features and spectrum distribution. Because the laser has the characteristics of the above, the laser processing has the following characteristics: precious because it is a non-contact processing, and high energy laser beam energy and its movement speed are adjustable, so it can achieve a variety of processing purposes. B it can undertake processing of a variety of metals, non-metallic materials, especially can processing and high hardness, high brittleness, and high melting point of materials. 2, the laser cutting mechanism based on its physical and chemical phenomena can be divided into the following form: vaporization cutting, melting cutting, the thermal oxidation melting cutting, fracture control cutting, wood cutting mainly vaporization cutting, metal cutting mainly melt cutting. Beam laser cutting board, the focus of a condenser is above board, high light effect over the wood, wood burning, evapotranspiration into sawdust and ashes; Beam with three kilograms same direction compressed air blowing, will burn, evapotranspiration sawdust dust blown away can achieve the goal of cutting. Adjust the focal length of the laser beam and a certain speed, can form a smooth, flat, and uniform cutting seam. Laser cutting metal materials, the same direction of blowing oxygen, oxygen combustion effect, make the combustion can produce more energy, the metal melt; Blowing effect and blow away the molten steel slag and neat, smooth and uniform kerf up and down. With laser cutting wood and metal speed, high precision and graphics accurately.
