Laser engraving machine is a kind of commonly used advertising production equipment, which can be divided into carbon dioxide (CO2) type, optical fiber cutting type and YAG type.

In terms of power and speed, laser engraving machines can be divided into many more detailed models, but they are suitable for gift engraving and marking industries, and only CO2 and YAG models are suitable.

The main difference between CO2 and YAG laser engraving machines is that the materials used to make laser are different. CO2 laser engraving machine generates laser by exciting the mixed gas molecules of cation and dioxide, while YAG laser engraving machine generates laser by exciting yttrium aluminum garnet crystal or crystal rod. Various light sources emit different laser wavelengths, so each engraving machine is suitable for carving different materials.

Longtai laser engraving machine, also known as laser cutting machine, is the most common in the gift industry. It is a flat laser engraving machine made of carbon dioxide (CO2) laser tubes. Lithographic laser engraving machines also use YAG laser tubes, but not many. For the plane laser engraving machine, the laser beam moves on the flat plate through a forward and backward moving cart.

Another engraving machine using carbon dioxide (CO2) laser is galvanometer type, also called galvanometer type. It controls the movement of the beam on the surface of the workbench by rapidly rotating the reflector, so that the beam can run at a high speed without moving the entire cart.

Common laser engraving and cutting machines on the market.

However, the galvanometer type also has its disadvantages. Its processing size is small (generally 12x12 inches or 14x14 inches). If the galvanometer type is used for cutting, the cutting process is not straight cutting, but has a certain radian. When the power reaches 100W, the power of the galvanometer laser engraving machine is equivalent to that of the flat plate laser engraving machine, up to 100W. However, at the same power, the galvanometer has a great speed advantage. The vibrating mirror is mainly used for marking, not for cutting. Their company also sells vibrating mirror type and planar CO2 laser engraving machines. In addition, at present, the speed of the flat laser engraving machine has become faster and faster, and the gap with the mirror module is smaller and smaller.

The reason for the widespread use of carbon dioxide (CO2) lasers is simple: they are extremely versatile. CO2 laser engraving machine can carve or mark plastic, acrylic, painted metal, glass, leather, paper, cloth, wood, marble, etc. It can also be used to cut many such materials. The only thing that cannot be carved is the metal without coating.

YAG lasers can be divided into two categories. The main difference between them is that YAG crystals are excited by flash or diode. The biggest difference between these two kinds of lasers lies in how they generate light to excite crystals to form laser beams. Compared with flash lamps, the laser produced by diode lasers is thinner and purer, and different from the high-power power required by flash lamps. " The key to the problem is that the laser wavelengths produced by the two are the same. "The diode YAG laser engraving machine is efficient, and the flash laser engraving machine is cheap. Both materials are more expensive than the CO2 laser engraving machine.

The advantage of laser engraving machine YAG is that its wavelength can be absorbed by metal, and it can also do well in equipment marking and other industrial applications. However, for YAG laser engraving machine, many materials cannot be carved, while carbon dioxide (CO2) laser engraving machine can carve, such as wood, paper, cloth, glass and some gypsum. The mechanical engraving machine has said so many laser engraving machines. It is necessary to mention the computer mechanical engraving machine that has been used in the gift industry for a long time. The mechanical engraving machine is still universal in the gift industry. Although YAG's laser engraving machine can mark metal, it is necessary to use a mechanical engraving machine to engrave deeper.

Because the hand feeling of characters and patterns carved by mechanical carving machines cannot be replaced, people always like traditional and classical things, which is the reason why mechanical carving machines are widely available, which is the natural psychology of people. When you see a sculpture, you always want to touch it.

If there is no laser engraving machine, your business will be greatly limited, and some businesses can only be done with mechanical engraving machines. Therefore, it is a good idea to have two types of machines at the same time, which can complement each other.
