Application of laser marking machine
on wood products
Wood products use laser engraving machine and CO2 laser marking machine to complete the marking. Because of the different materials, the marking effect is not the same. Let's introduce it in detail:
Let's look at the color aspect first: ordinary mechanical engraving cannot engrave points of varying thickness in an economical way, and thus does not have a grayscale representation. The laser engraving machine realizes engraving by means of dot punching, and has the natural advantage in gray scale performance. For this reason, the gray scale expression is used as much as possible in the engraving design. This has the advantage of reducing the coloring process and saving the cost; on the other hand, enriching the representation of the engraving and increasing the level of the graphics. When the user is using, first make different grayscale fills in the graphics (the text should be converted into graphics first), and the engraving output selects the black and white mode. You can try the effect of different dots, and the precision generally does not exceed 500dpi. After wood carving, there is generally a feeling of being burned. Matching the color of the wood has an original artistic beauty. The depth of the color depends mainly on the laser power and the engraving speed. But some woods are usually softer in texture, and you can't change their color (such as birch) anyway. For the coloring of the finished product, an acrylic pigment can be used.
Introduction to the following materials:
1. Logs: Wood is by far the most commonly used laser processing material and is easy to engrave and cut. Light wood like birch, cherry or maple is easily vaporized by laser and is therefore more suitable for engraving. Each type of wood has its own characteristics, some of which are dense, such as hardwood, which requires greater laser power for engraving or cutting. We recommend studying the engraving properties first before carving less familiar wood.
2. Plywood: Carving on plywood is not much different from carving on wood, but one thing to note is that the depth of engraving should not be too deep. The edge of the cut plywood will also be black like wood. The key is to see if the plywood is made of that kind of wood.
In general, engraving on wood is usually a vulture, and the depth of engraving is generally required to be deep. This power is generally set higher, such as encountering harder wood may make the engraved graphics color darker. If you want to make the color lighter, you can increase the speed of engraving and try to sculpt several times. Some woods will produce some fumes attached to the surface of the wood. If the wood has been painted with a damp cloth, it can be carefully wiped off. If it is not painted, it may not be cleaned, causing the surface of the finished product to be stained.
