Friends who have used casters everyone knows that all kinds of industrial caster brackets are surface treated; whether yours is a fixed caster bracket or universal caster bracket, caster manufacturers why do bracket surface treatment? This is mainly because the stent are made of iron or steel stamping, and in our daily use, due to iron or steel easily oxidized with oxygen thus making the whole stent rust, affecting the surface and the normal use, which is why so many caster manufacturers have to caster stents after surface treatment. Here are a few common surface treatment methods and their characteristics.
Electroplating: Electroplating is through electrolysis, metal ions deposited on the surface of the workpiece to form a layer of metal film. Electroplating can make the surface of the caster with a metallic luster, improve wear resistance and extend the service life. The color and thickness of the plating layer can be adjusted according to customer demand.
2. Anodizing: Anodizing is a kind of electrochemical treatment, which makes the metal surface corrosion-resistant and abrasion-resistant by forming an oxide film on the surface of aluminum, magnesium, zinc and other metals. The anodic oxidation surface treatment has good anti-scratch performance, and at the same time, the color is rich and beautiful appearance.
3. Paint spraying: Paint spraying is to spray paint on the surface of the workpiece by spray gun to form a layer of protective film. Spray painting can make the casters have various colors and textures to enhance the beauty of the product. Spray paint treatment has good adhesion and wear resistance, but there may be uneven surface.
4. Galvanizing: Galvanizing is the deposition of zinc ions on the surface of the workpiece to form a thin film of zinc alloy by means of electrolysis. Zinc plating can improve the corrosion and wear resistance of the caster surface and prolong the service life. The color of galvanized layer is usually silver-white, which has a certain degree of aesthetics.
5. Plastic spraying: Plastic spraying treatment is through the compressed air to form a strong air flow, will be loaded in the container of powder to the spray gun mouth, in front of the spray gun mouth of the high-voltage electrostatic force, the formation of an electrostatic field. Coating powder after the electrostatic field itself will also carry an electric charge, under the action of electrostatic force, the charged powder will be attracted by the opposite polarity workpiece, so that the powder can be firmly adsorbed on the surface of the workpiece. The quality of the coating formed by plastic spraying is very good, and the appearance grade can reach up to grade 9, and the anti-corrosion performance will be better. Zhuo Ye manganese steel casters with this treatment.
The above are the common surface treatment methods of industrial casters and their characteristics. When choosing the surface treatment of casters, you need to choose the appropriate treatment according to the specific application scenarios, the use of the environment and customer demand.
