What are the processing techniques for wheel hub surface treatment

Basic Craft

Baking paint: Using the "three spray and three bake" technology, it has a variety of colors and is affordable, widely used in ordinary car models and colored wheel hubs.

Electroplating: Metal ions (such as chromium and nickel) are deposited on the surface of the wheel hub through electrolysis, forming a mirror or deep bright surface that is corrosion-resistant and wear-resistant. It can be classified into pure electroplating, water electroplating, silver electroplating, and other types.

Drawing: Using professional equipment to polish parallel fine lines on the surface of the wheel hub, preserving the natural metal color, combining beauty and scratch resistance, and convenient daily maintenance.

Spray painting/spraying robot: suitable for large-scale production, uniform and stable spraying, ensuring high quality.

Color matching: Using multiple colors or process combinations in different areas of the wheel hub to enhance visual hierarchy and design sense.

Polishing (precision polishing): Achieving a mirror effect through mechanical grinding and polishing, with high glossiness, delicacy, and smoothness.

Milling: Using CNC machine tools combined with diamond or PCD cutting tools, cutting out local high gloss metal surfaces in areas such as spokes, with a permanent texture that does not peel off.

Hollow out: Cutting or carving off non load bearing parts of the wheel hub to achieve lightweighting, optimize aerodynamics, and enhance visual impact.

Left and right rotation process: Manufacturing mirror symmetric left and right wheel hubs to ensure that asymmetric design elements (such as air ducts) perform optimally on both sides.

Matte/deep gun gray full coating: commonly used for modifying wheel hubs, with strong sportiness and durability.

Transparent gloss/mirror coating: commonly used for forging aluminum wheels, creating a high gloss mirror effect through transparent paint or powder coating.
