Laser engraving machine industry development history

Carving is an ancient art, and in the course of history, the world has developed a variety of sculpting techniques with exquisite skills, such as jade carving, wood carving, stone carving and so on.

Since the twenty-first century, with the development of laser technology applications and the widespread use of computer technology, two disparate technical fields have intersected and fused into the “laser engraving technology”. Laser has become a tool for engraving, and the object of engraving is not only limited to the above-mentioned types, more glass, steel, plastic and other types of engraving. Laser engraving processing is based on the use of CNC technology, laser as the processing medium. Processing materials under laser irradiation instantaneous melting and vaporization of physical denaturation, to achieve 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. It is not affected by the elasticity and flexibility of the material, which is convenient for processing soft materials. Its high processing accuracy and speed make its application field wide.

The process of engraving and cutting with a laser engraver is as simple as using a computer and printer to print on paper. Users can use a variety of graphic processing software, such as Lightburn, to design graphics under PC operation, and vectorized graphics and a variety of CAD files can be easily “printed” into the engraving machine. The difference is that printing applies toner to paper, while laser engraving shoots laser light onto wood, acrylic, plastic, metal, stone and almost every other material.

Laser engraving machine, as the name implies, is an advanced device that uses laser light to engrave the material to be engraved. The laser engraving system consists of 3 main parts: the high energy laser, the laser transmission system, and the optical system. The machine regulates the energy per unit area by adjusting the focal length.

The high processing efficiency of laser engraving machine and its smooth processing edge make it widely used. Laser engraving machines are used in various industries, such as advertising industry, woodworking industry, decorative products industry, decorative decoration industry, construction industry, sheet metal industry, etc.

The classification of laser engraving machine is mainly divided into solid state laser engraving machine, gas laser engraving machine, and semiconductor laser engraving machine.

Laser engraving machine can improve the efficiency of engraving, make the surface of the engraved place smooth and round, rapidly reduce the temperature of the engraved non-metallic materials, reduce the deformation and internal stress of the engraved object, so it can be widely used in the field of fine engraving of various non-metallic materials.

So far, the application of engraving machine is spread in almost every industry, becoming a commonplace equipment in our daily work. Nowadays, it is mainly used in the advertising industry, craft industry, mold industry, construction industry, printing and packaging industry, wood industry, decoration industry, leather industry…

Decoration industry

The first is logs, which is wood that has not been processed. It is one of the most common laser processing materials in our daily life and can be easily engraved and cut. For example, light-colored woods, such as birch, cherry or maple, are easily vaporized by the laser and are therefore more suitable for engraving. However, since each wood has its own characteristics, we have to choose the wood according to the specific object we want to engrave. We recommend studying the characteristics of the engraver first before carving less familiar woods.
The next is plywood, which is a man-made wood panel and one of the common materials used for furniture. Carving on plywood is actually not much different from carving on wood, except for one thing to note, the carving depth should not be too deep. The edges of the cut plywood will also be blackened like wood. But how dark it is, the key is to see what kind of wood is used to manufacture the plywood.

Printing & Packaging Industry

With the widespread use of laser engraving machines, the printing and packaging industry is also gradually applying laser engraving technology. The most common type of packaging in this industry is corrugated carton packaging. However, corrugated carton 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 with consumers in the sales process, such as color boxes, white boxes, gift boxes, etc. Transportation packaging generally belongs to the outer packaging, whose main role is to facilitate storage and transportation, such as cardboard boxes, corrugated boxes and so on.

Because of the low production cost of laser engraving on paper packaging materials, which is only one-fourth of the cost of resin plates, laser engraving plates are commonly used in the current printing and packaging industry as printing plates for corrugated packaging.

Craft Industry

Laser engraving crafts are engraving crafts that use a high energy dense laser beam projected onto the surface of the material to make physical and chemical changes to the surface of the material to obtain visible patterns.

Laser engraving crafts can be divided by material into: paper laser engraving crafts, fabric 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, etc.

Leather Industry

The leather industry uses laser engraving machine to break the traditional manual and electric shear slow speed, difficult to layout, low efficiency and material serious waste phenomenon of the difficulty.

Its fast speed and simple operation have brought very great benefits to the development of the leather industry. People only need to input the graphics and dimensions for cutting into the computer, and the laser engraving machine will cut the whole sheet of material into the finished product that the user needs according to the data on the computer. There is no need for knives or molds, and at the same time, it saves a lot of human resource input. So laser engraving machine is also widely used in leather industry.
