Surface Treatment Process for Sheet Metal Processing Parts

The surface treatment of sheet metal parts is also a very important part of the sheet metal processing process, as it has the effect of preventing the parts from rusting and beautifying the appearance of the products.

Several common surface treatments for sheet metal processing are: brushed, sandblasted, baked, powder coated, electroplated, anodized, and silk screened. Since the surface of some sheet metal materials does not have the ability to prevent rust and corrosion, effective surface treatment is very necessary. Surface treatment of sheet metal parts can improve the product's service life in harsh environments, or to achieve a specific surface effect or function.

Sandblasting

Through the sand blasting machine wind will be sand particles to the surface of the workpiece, the workpiece surface to form a layer of dense pits, the main role is to remove the surface of the workpiece dirt, rust and corrosion, to increase the adhesion of the surface of the workpiece for the subsequent surface treatment way to do the preparation. This surface treatment process commonly used materials: cold rolled sheet, hot rolled sheet, aluminum, etc..

Paint spraying

Generally refers to liquid spraying, his process has two kinds: liquid baking paint and self-drying spray paint, self-drying is sprayed at room temperature can be natural curing, lower cost, but the effect with the baking paint can not be compared. Spray paint color effect will be better, paint film thickness is relatively thin, suitable for some precision products, the cost is higher. This surface treatment process commonly used materials: cold rolled sheet, hot rolled sheet and so on.
