Metal wipers are specially treated during the manufacturing process, such as electrophoretic painting and anodizing, to effectively enhance their weather resistance. These treatments form a hard protective film on the surface of the metal wiper, which can resist ultraviolet radiation, reduce surface aging and fading, and extend its service life.
Electrophoretic painting is a common surface treatment method for metal wipers. In the electrophoretic painting process, the metal wiper is first pre-treated to remove oil and rust, and then immersed in a solution containing paint particles. Under the action of the electric field, the paint particles will be evenly attached to the surface of the metal wiper to form a hard coating. This coating can effectively resist ultraviolet radiation, prevent sunlight and other weather factors from damaging the metal wiper, and slow down its aging and fading. At the same time, electrophoretic painting can also provide better corrosion resistance, making metal wipers less susceptible to erosion by humid environments and rain.
Anodizing is also a common surface treatment method for metal wipers. Anodizing is to provide better weather resistance by forming an oxide film on the surface of the metal wiper. In the anodizing process, the surface of the metal wiper is placed in a solution containing electrolyte, and a dense and hard oxide film is formed on the surface of the metal wiper by applying an external current. This oxide film can effectively isolate the contact between the metal wiper and the external environment, prevent oxidation and corrosion, and improve the weather resistance and service life of the metal wiper.
Through special treatments such as electrophoretic painting and anodizing, metal wipers can form a hard protective film to provide better anti-aging performance and resist the influence of sunlight, oxidation and other weather factors. These treatment methods can not only extend the beauty and service life of metal wipers, but also improve their resistance to harsh weather conditions such as pressure and wind and rain, ensuring driving safety.
