Laser engraving machine, sculpture is an ancient art. In the long river of history, our ancestors developed a variety of exquisite sculpture techniques, such as tooth carving, jade carving, wood carving, stone carving, clay carving, face sculpture, bamboo carving, bone carving, inkstone carving, etc.
Since the beginning of the 21st century, with the development of laser technology applications and the wide application of computer technology, two irrelevant technical fields have intersected and merged into “laser engraving technology”. Laser has become a tool for engraving, and the engraving objects are not limited to the above-mentioned types, and there are more types of engravings such as glass, steel, and plastic.
Laser engraving is based on numerical control technology, and laser is the processing medium. The physical denaturation of the instant melting and gasification of the processed material under laser irradiation achieves the purpose of processing.
Laser processing features: no contact with the surface of the material, not affected by mechanical movement, the surface will not be deformed, generally no need to fix. Not affected by the elasticity and flexibility of the material, it is convenient to process soft materials. High processing precision, fast speed, wide range of applications.
Laser engraving machines have high processing efficiency, smooth processing edges, and a wide range of applications. Laser engraving machines are used in various industries, such as advertising industry, woodworking industry, decoration industry, decoration industry, construction industry, sheet metal industry, etc.
So far, engraving machines have been used in almost every industry and become common equipment in our daily work. Now, it is mainly used in advertising industry, handicraft industry, mold industry, construction industry, printing and packaging industry, wood industry, decoration industry, leather industry…
The first is logs, which are unprocessed wood. It is the most common laser processing material in our daily life, and it is also easy to be engraved and cut. Such as light-colored wood, birch, cherry wood or maple, etc., they are easily vaporized by laser, so they are more suitable for engraving. However, since each wood has its own characteristics, when we choose wood, we should choose according to the specific object we want to carve.
The second is plywood, which is a kind of man-made wood board and one of the commonly used materials for furniture. Carving on plywood is actually not much different from carving on wood, but one thing to pay attention to is that the depth of carving should not be too deep. The edges of the cut plywood will also be blackened like wood, but the degree of blackening depends on the kind of wood used to make the plywood.
Printing And Packaging
With the widespread application of laser engraving machine, printing and packaging printing plates have gradually applied laser engraving technology. The most common packaging in the printing and packaging industry is corrugated box packaging. However, corrugated box packaging can be divided into two categories, one is sales packaging, and the other is transportation packaging. Sales packaging generally belongs to the inner packaging, which meets consumers during the sales process, such as color boxes, white boxes, gift boxes, etc. Transportation packaging is generally an outer packaging, and its main function is to facilitate storage and transportation, such as cartons, corrugated boxes and so on.
Since the plate-making cost of laser engraving on paper packaging materials is low, only a quarter of the cost of the resin plate, laser engraving plate-making is generally used as the printing plate for corrugated box packaging in the current printing and packaging industry.
Laser engraving handicrafts refer to the use of high-energy plotted laser beams projected onto the surface of the material to cause physical and chemical changes on the surface of the material, thereby obtaining engraved handicrafts with visible patterns.
Laser engraving crafts can be divided into: paper laser engraving crafts, cloth laser engraving crafts, bamboo laser engraving crafts, leather laser engraving crafts, resin laser engraving crafts, glass engraving crafts, metal laser engraving crafts, jewelry and jade laser engraving Crafts…
The use of laser engraving machines in the leather industry has broken the problems of slow speed, difficult typesetting, low efficiency and serious material waste of traditional manual and electric shears. Its fast speed and simple operation have brought great benefits to the development of the leather industry. Just input the graphics and size to be cut into the computer, and the laser engraving machine will cut the entire material into the finished product required by the user according to the data on the computer. There is no need for tools or molds, and at the same time, it can save users a lot of human resources. Therefore, laser engraving machines are also widely used in the leather industry.
Compared with traditional engraving methods, laser engraving machines have many advantages: the edges of the leather engraved by it will not turn yellow, and the edges will be closed or curled automatically, without deformation, hardening, consistent and accurate size; it can engrave any complex Shape; high efficiency, low cost, computer-designed graphics, can engrave lace of any shape and size; processing has no mechanical pressure on the workpiece; safe operation, simple maintenance, etc.
Laser engraving machines are mainly composed of optical systems, mechanical systems and numerical control systems. Developed countries such as Europe and the United States first began to use lasers for processing and manufacturing, and occupied a large market share for a long time. Benefiting from the continuous recovery of the global economy and the deepening of national strategies, the global manufacturing industry has shifted to developing countries, and the market share of the laser industry in the Asia-Pacific region has grown rapidly. In the process of upgrading the manufacturing industry, developing countries gradually use laser equipment to replace traditional equipment, which is one of the most important driving forces for the growth of the global laser processing industry market.
