The laser engraving machine can improve the efficiency of our engraving, make the surface of the engraved place smooth and round, quickly reduce the temperature of the engraved non-metallic material, and reduce the deformation and internal stress of the engraved object; it can be widely used for various It can be said that the laser engraving machine is a high-tech product in the world today, and the product has a high technical content of optical, mechanical and electrical integration. In the mid to late 1990s, with the successful development of laser engraving technology, the engraving industry began to develop rapidly. Up to now, the application of engraving machine has spread in almost every industry, and it has become a common equipment in our daily work. Now, it is mainly used in the advertising industry, craft industry, mold industry, construction industry, printing and packaging industry, wood industry, decoration industry, leather industry... Let us briefly understand the laser engraving machine in various industries. in the application.
1. Application of laser engraving machine in decoration industry in all walks of life
There are many applications of laser engraving machines in the decoration industry. The following is an introduction to the engraving of wood:
The first is logs, which are unprocessed wood. It is one of the most common laser processing materials in our daily life, and it is also easy to be 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 type of wood has its own characteristics, we should choose wood according to the specific objects we want to carve. We recommend researching the characteristics of the engraving machine before engraving unfamiliar woods.
Next is plywood, which is a 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 note is that the carving depth should not be too deep. The edge of the cut plywood will also turn black like the wood, but the degree of blackening depends on the kind of wood the plywood is made of.
Generally speaking, the engraving on wood is usually in the shadow, and the engraving depth is generally required to be deep, so the power is generally set to be relatively high. If you encounter hard wood it may make the engraved graphic presentation darker. If you want to make the color lighter, you can increase the engraving speed and try to engrave several times. Some wood will produce some oily smoke attached to the surface of the wood when carving, if the wood has been painted. It can be wiped off carefully with a damp cloth, if it is unpainted, it may not be wiped clean, causing contamination of the finished surface.
Second, the application of laser engraving machine in all walks of life in printing and packaging
With the wide application of laser engraving machines, the printing and packaging industry 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. Transport packaging generally belongs to the outer packaging, which is basically not suitable for consumption during the sales process. 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 one quarter of the cost of resin plate, so in the current printing and packaging industry, laser engraving plate-making is generally used as the printing plate for corrugated box packaging.
The laser engraving machine realizes engraving in the way of dots, which has a natural advantage in grayscale performance. For this reason, the grayscale representation is used as much as possible in the engraving design. The advantage of this is that it reduces the coloring process and saves the cost; on the one hand, it enriches the expressive means of engraving and increases the level of graphics.
3. The application of laser engraving machine in all walks of life
Laser engraving handicrafts refer to the engraving handicrafts that use a high-energy conspiracy laser beam to project onto the surface of the material to make physical and chemical changes on the surface of the material, thereby obtaining visible patterns.
Laser engraving crafts can be divided 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 jade laser engraving crafts...
Next, I will mainly introduce the engraving of laser engraving machine on plexiglass handicrafts.
The most common material in our daily life, acrylic, is actually a kind of plexiglass. It is easy to be cut and carved into various shapes and sizes, and the cost is relatively low, so it naturally becomes a craft industry One of the most commonly used carving materials. The plexiglass produced by casting method has a very white frosting effect after laser engraving, which is in sharp contrast with the original transparent texture, and can produce very good results after engraving; It is still transparent and does not have a sufficient contrast effect, so it is relatively rarely used. Therefore, when we buy plexiglass, we must pay attention to that kind of high purity, otherwise the purchased plexiglass material may melt when engraving or cutting.
Fourth, the application of laser engraving machine in all walks of life leather
The use of laser cutting machines in the leather industry breaks the problems of traditional manual and electric shears, such as slow speed, difficult typesetting, low efficiency and serious material waste. It is fast and easy to operate, which has brought great benefits to the development of the leather industry. You only need to 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 you need according to the data on your computer. There is no need for knives and molds, and at the same time, it can save you a lot of human resources. Therefore, laser engraving machines are also widely used in the leather industry.
Compared with the traditional cutting method, the laser cutting machine has many advantages: the edge of the leather it cuts does not turn yellow, and it also automatically closes or curls the edges, does not deform, does not harden, the size is consistent and accurate; it can be cut Arbitrary complex shape; high efficiency, low cost, computer design graphics, can cut any shape and size of lace; processing without mechanical pressure on the workpiece; safe operation, simple maintenance, etc.
Due to the combination of laser and computer technology, as long as the user designs the pattern on the computer, it can be output and the engraving pattern can be changed at any time, realizing the concept of designing and producing products. It can be said that the emergence of laser engraving machines has greatly promoted the development of the leather industry.
Practice has proved that laser processing is the best choice for energy-saving processing and environmental protection processing.
