Laser engraving, also known as laser engraving or laser marking, is a process of surface treatment using optical principles. The keys of mobile phones and electronic dictionaries are mostly used to carve marks by the chemical and physical changes of surface materials caused by the light energy of the laser beam, or by burning some materials to show the graphics and characters to be etched.
According to different carving methods, it can be divided into dot matrix carving and vector cutting.
1. Dot matrix engraving: like high-definition dot matrix printing; The laser head swings left and right to carve a line composed of a series of points each time, and then the laser head moves up and down simultaneously to carve multiple lines, finally forming a whole page of images or characters; The scanned graphics, text and vectorized graphics and text can be carved with dot matrix.
2. Vector cutting: Different from dot matrix carving, vector cutting is carried out on the outer contour line of graphics and texts. This mode is usually used for penetrating cutting on wood, paper, acrylic and other materials, as well as marking on the surface of a variety of materials!
The products made by radium carving and silk screen printing have similar visual effects from the outside, but in fact, they are quite different. Here is a brief introduction to their differences:
1. Radium carving products, fonts and patterns are transparent; Silk screen products are light tight.
2. For radium carving products, the color of fonts and patterns is the color of materials, and the background color is the color of ink; Silk screen products are just the opposite of radium carving products.
3. In terms of wear resistance, radium carving is higher than silk screen
4. The principles used in the two processes are different. The optical principle used in the radium carving can be used for surface treatment, while the silk screen is a physical principle, which makes the ink stick to it.
5. The price is different, but the price is determined by the difficulty of fonts and patterns.
