Common surface treatment methods for stamping parts

Precision Technology Co., Ltd. is a company dedicated to the production of precision stamping parts. Commodities are widely used in digital equipment, power switches, electronic devices, household appliances, auto and motorcycle accessories, communication tools and other industries. The purpose of the surface treatment of precision stamping parts is to make the surface of the product beautiful and the actual effect of corrosion resistance. There are the following types of surface solutions. Let's see which ones are available. Electroplating process: The precision stamping parts are immersed in the solution with the deposited metal compound, and the metal material of the electroplating process is dissolved and accumulated on the component according to the plating solution with the amount of electric current. General electroplating processes include hot-dip galvanizing, copper, nickel, chromium, copper-nickel alloys and so on. Oxidation treatment: can be divided into organic chemical oxidation and anodic oxidation treatment. Stainless steel passivation: pure iron and pure aluminum are reflected in sulfuric acid or concentrated sulfuric acid, and the molecules on the surface react with the acid, resulting in a layer of high-density air oxide film, which prevents the internal chemical substances from reacting with the concentrated acid again and plays a protective effect . The principle of electrophoresis: It is to inlay the paint on the surface of the raw material under the effect of the external electric current. Its characteristic is that the color is rich and colorful, but the adhesion is poor, and the color is more difficult to manipulate. Mechanical plating: It is to impact the surface of the commodity according to the particles of the coated metal material, and the plating layer is cold welded to the surface of the precision stamping part.
