The sandblasting metal sign is a method of engraving with a computer. The instant sticker is glued to the metal plate, and the text graphic is sandblasted to form a sand surface effect, and then oxidation treatment is performed, so that the metal plate is presented with gold dust. The effect of the metal signage.
Sandblasting metal signage process:
1) Pre-treatment stage of sandblasting process: The pre-treatment stage of sandblasting process refers to the treatment of the surface of the workpiece before the workpiece is sprayed and sprayed with the protective layer. The quality of the pre-blasting process is good or bad, which affects the adhesion and appearance of the coating, the moisture resistance and corrosion resistance of the coating. The pre-treatment work is not done well, and the rust will continue to spread under the coating, causing the coating to fall off. After carefully cleaned the surface and the generally cleaned workpiece, the coating is compared by exposure method, and the life span can be 4-5 times. There are many ways to clean the surface, but the most common methods accepted are: solvent cleaning, pickling, hand tools, power tools.
2) Sandblasting process stage: The sandblasting process uses compressed air as the power to form a high-speed jet beam, and sprays the spray material at a high speed to the surface of the workpiece to be processed, so that the appearance of the outer surface of the workpiece changes, due to the impact of the abrasive on the surface of the workpiece. The cutting action gives the workpiece surface a certain degree of cleanliness and different roughness, which improves the mechanical properties of the workpiece surface.
