How Are Sandblasted Metal Nameplate Made | WEIHUA

The role of signs in everyone's life is very huge, the normal order of life is dependent on signs, the following, custom metal nameplate manufacturers to produce metal signs in one of the process of metal signs in the sandblasting signs

Metal sign production process of sandblasted metal signs

The production of metal marks mainly includes metal sun marks, metal screen printing, metal corrosion marks, metal electroplating and metal electroforming marks, metal thermal transfer printing and metal sandblasting marks, etc.On this basis, we understand the metal logo production process in the metal flat sun mark, metal screen printing mark, metal corrosion mark, metal electroplating and metal electroforming mark, metal thermal transfer mark.

Gold spray logo is the use of a computer to immediately adhere the metal out of the pattern on the metal sheet, through the text graphics sandblasting, the formation of sand surface effect, and then oxidation treatment, so as to make the metal sheet to present the effect of gold. 

Process flow of sandblasted metal signs:

1. Pre-treatment sandblasting process stage:

The pre-treatment sandblasting process stage refers to the required treatment of the workpiece surface before the workpiece is sprayed and coated with a protective layer.The quality of the treatment before sandblasting directly affects the adhesion, appearance, moisture resistance and corrosion resistance of the coating.

Early treatment work is not done well, rust will continue to spread under the coating, so that the coating flakes off.Careful cleaning of the surface and the general simple cleaning of the workpiece, using the method of exposure coating comparison, its service life can be 4-5 times.There are many ways to clean surfaces, but the most commonly used are solvent cleaning, pickling, hand tools, and power tools.

2. Spraying technology stage:

the spraying technology forms a high-speed spray beam with compressed air as the power to spray the high-speed spray on the workpiece surface that needs to be treated to change the appearance of the workpiece surface.Due to the impact and cutting effect of abrasive materials on the workpiece surface, the workpiece surface gets a certain degree of cleanliness and roughness, and the mechanical properties of the workpiece surface are improved.

The above is organized and released by customized metal nameplate suppliers. If you do not understand, welcome to consult us!
