Powder coating for automobile wheel hub- Durable, Custom & OEM Supply

Surface Finish Options Overview

Standard automobile powder coating is mainly used for automobile parts, such as automobile engines, aluminum wheels, chassis, filters, joysticks, mirrors, wipers and horns. With the rapid growth of cars in recent years, powder coatings for aluminum wheels have developed rapidly.

Standard automobile powder coatings include epoxy, epoxy polyester, polyester, polyurethane and acrylic. They can meet the various requirements of automobile parts coating, such as appearance decoration, weather resistance, chemical resistance, scratch resistance, UV resistance, etc.

Standard aluminum wheel powder coating is mainly wheel base powder and glazing transparent powder. Wheel base powder is mainly epoxy, epoxy polyester mixed, pure polyester, etc., and glazing transparent powder is mainly polyester, GMA acrylic, etc.

Standard aluminum wheel base powder is to improve its corrosion resistance and extend its service life, and to improve its appearance decoration. Base powder is mainly divided into high gloss, semi-gloss and matte in terms of gloss.

Why Choose Powder Coating for Automotive Wheels?

Powder coating has become the preferred finishing solution for automotive wheels due to its durability, corrosion resistance, and premium appearance. Unlike liquid paint, powder coating forms a tough and uniform layer that protects wheels against harsh road conditions, UV rays, chemicals, and scratches. For car manufacturers, aftermarket suppliers, and wheel refurbishing businesses, powder coating ensures a long-lasting and cost-effective finish.

FAQ

1. What is Powder Coating?

Powder coating is a dry finishing process used to apply a protective and decorative coating on metal or other surfaces. Instead of using liquid paint, fine powder particles (usually made of polyester, epoxy, or hybrid resins) are electrostatically charged and sprayed onto a conductive surface. The coated object is then baked in an oven, where the powder melts, flows, and cures into a smooth, durable finish.

Key features:

Durable, hard finish

Resistant to scratches, corrosion, and UV

Environmentally friendly (no VOCs)

2. Benefits of Powder Coating

Powder coating offers several advantages over traditional liquid painting:

Durability: Resistant to chipping, scratching, fading, and wear.

Corrosion Protection: Provides excellent protection against rust and chemicals.

Environmentally Friendly: No volatile organic compounds (VOCs) and minimal waste.

Efficiency: Overspray can be collected and reused, up to 99% material utilization.

Uniform Finish: Smooth, even coating without runs or drips.

Cost-Effective: Single-coat systems can achieve high film thickness, reducing labor and energy.

Aesthetic Variety: Wide range of colors, textures, and effects.

3. What Temperature to Cure Powder Coating

The curing temperature depends on the type of powder used:

Epoxy powder: ~160–200°C (320–392°F)

Polyester powder: ~180–210°C (356–410°F)

Hybrid (Epoxy-Polyester) powder: ~180–200°C (356–392°F)

Typical curing time: 10–20 minutes depending on thickness and oven type.

Always follow the powder manufacturer’s specifications for best results.

4. Process for Powder Coating

The powder coating process usually follows these steps:

Surface Preparation:

Clean the surface thoroughly (remove oil, grease, rust, or dirt)

Methods: chemical cleaning, sandblasting, or phosphating

Pre-Treatment:

Apply a conversion coating or primer if needed to improve adhesion

Powder Application:

Spray the powder using an electrostatic spray gun or fluidized bed

Curing:

Bake the coated object in an oven at the recommended temperature for the powder type

The powder melts and forms a continuous, smooth film

Cooling & Inspection:

Let the coated item cool

Inspect for defects, uniform coverage, and desired thickness

5. How to Spray Powder Coat

Equipment Needed:

Electrostatic spray gun

Compressed air supply

Powder feed hopper or container

Grounding of the object

Steps:

Ground the object: Ensures the charged powder is attracted to the surface.

Spray evenly: Hold the gun 6–12 inches from the surface, moving in smooth, overlapping strokes.

Apply sufficient powder: Ensure full coverage without excessive buildup.

Cure immediately: Transfer the sprayed item to the curing oven to fuse the powder into a solid coating.

Tips:

Maintain consistent speed and distance while spraying.

Use proper ventilation to reduce airborne powder accumulation.

Test a small area to check film thickness and color before full application.
