Laser engraving machines can be divided into carbon dioxide (CO2), galvanometer and YAG.

According to size, power and speed, laser engraving machines can be divided into many types, but only carbon dioxide (CO2) and YAG are suitable for the gift industry. The main difference between CO2 laser engraving machine and YAG laser engraving machine is that the materials used to generate laser are different. Carbon dioxide (CO2) type generates laser by exciting mixed gas molecules of cation and dioxide, while YAG type generates laser by exciting yttrium aluminum garnet crystal or crystal rod. Different light sources emit different laser wavelengths, so each engraving machine is suitable for engraving different materials.

Flying light, also known as flat laser engraving machine, is the most common flat laser engraving machine using carbon dioxide (CO2) laser tube in the gift industry. Flat plate laser engraving machines also use YAG laser tubes, but few. For the flat plate laser engraving machine, the laser beam moves on the flat plate through a car moving back and forth.

Another engraving machine using carbon dioxide (CO2) laser tube is galvanometer type, also known as galvanometer type. It controls the beam to move on the worktable through a fast rotating reflector. This allows the beam to travel at high speed because it does not have to move the entire trolley.

However, the galvanometer type also has shortcomings. Its processing size is small (usually 12x12 inches or 14x14 inches). If the galvanometer type is used for cutting, it does not cut straight, but has a certain radian. When it rises to 100 watts, the galvanometer type can have the same power as the flat plate laser engraving machine, up to 100 watts, but under the same power, the galvanometer type has great advantages in speed. Galvanometer is mainly used for marking, not cutting. Their company also sells galvanometer and flat plate CO2 laser engraving machines. In addition, at present, the speed of flat plate laser engraving machine has become faster and faster, and the speed difference between flat plate laser engraving machine and galvanometer type is smaller and smaller.

The reason why carbon dioxide (CO2) laser tubes are widely used is simple: they are widely used. Carbon dioxide (CO2) laser engraving machine can carve or mark plastic, acrylic, painted metal, glass, leather, paper, cloth, wood, marble and so on. It can also be used to cut many such materials. The only thing that cannot be carved is the metal without coating.

YAG laser is divided into two main types. The main difference between them is whether YAG crystal is excited by flash lamp or diode. The main difference between the two is how to generate light to excite the crystal to form a laser beam. Compared with the flash lamp laser machine, the diode laser machine produces a thinner laser beam and purer light, and does not need a high-power power supply like the flash lamp. "The key is that both produce the same wavelength laser." diode YAG laser engraving machine is efficient, while flash laser engraving machine is cheaper. Both are more expensive than CO2 laser engraving machine.

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

Because the hand feel of the inscriptions and patterns carved by the mechanical engraving machine can not be replaced, people always like traditional and classic things. This is the reason why the mechanical engraving still exists widely. This is people's natural psychology. When you see a sculpture, you always want to touch it.

There will be many restrictions on your business without laser engraving machine, and some businesses can only be done with mechanical engraving machine. Therefore, it is a good idea to have both mechanical engraving machine and laser engraving machine. They can complement each other
