Surface treatment methods and characteristics of industrial casters

Friends who have used casters know that all kinds of industrial caster brackets have been surface-treated; whether yours is a fixed caster bracket or a swivel caster bracket, why do the caster manufacturers need to surface the bracket? This is mainly because the brackets are stamped with iron or steel, and in our daily use, because iron or steel is easily oxidized with oxygen, the entire bracket will rust, affecting the surface and normal use. This is why so many Caster manufacturers must subject the caster bracket to surface treatment.

The caster bracket has a lot of surface treatment. We usually see galvanization. Because of its strong applicability and low cost, everyone is also fond of it; what are the surface treatment methods for the caster bracket? And what are the differences in the surface treatment characteristics of these caster brackets?

Galvanized: Features: The new oxide is denser and protects the inner metal from oxidation and corrosion.

Plastic spray: Features: Compared with traditional spray paint, it is more resistant to friction and impact. The appearance of the coating is excellent in quality, and the adhesion and mechanical strength are strong.

Color galvanized: Features: protect the internal metal from corrosion, and the appearance of the product is more beautiful.

Electrophoretic: Features: strong adhesion, the paint film is not easy to fall off, continuous bending does not break the skin, and the thickness of the paint film in any part of the workpiece is uniform. Eliminates the undesirable faults such as crusts and tear marks during spraying. Comply with environmental protection, water-based paint, non-toxic, non-polluting, and no residues of harmful substances.


Regardless of whether the caster bracket is Galvanized, Plastic spray, Color galvanized or Electrophoretic, these surface treatments are to prevent the caster bracket from being corroded. And their surface treatment methods are different, and their characteristics are different, so the final effect is also different. Therefore, when we choose which type of caster surface treatment method, we should choose different surface treatment methods according to the needs.
