How is the surface of the sheet metal prototype treated? In order to let you know more about the surface treatment process of sheet metal, we introduce the surface treatment process commonly used in sheet metal prototype. Such as: spraying, electroplating, electrophoresis, sandblasting, wire drawing, anodic oxidation, etc. Today I'm going to introduce you to electrophoresis and sandblasting.
Electrophoretic coating has the advantages of fullness, uniformity, flatness and smoothness, and the hardness, adhesion, corrosion resistance, impact performance and permeability of electrophoretic coating film are obviously superior to other coating processes. Mainly used in stainless steel, aluminum alloy, etc., can make the product show a variety of colors, and maintain metal luster, while increasing the surface performance, with good corrosion resistance.
There are two kinds of sandblasting: mechanical sandblasting and air pressure sandblasting, each of which is divided into manual, non-automatic or continuous automatic ways. Manual air pressure sandblasting machine is widely used in China, which is suitable for medium and small parts of various complex shapes.
