L-shaped headlight mounting bracket galvanized

In order to improve the durability and aesthetics of headlight brackets, different surface treatment processes are widely used in the manufacturing process. The following are several common treatment methods and their characteristics:

1. Galvanizing
Process principle
Galvanizing is to cover the surface of the bracket with a layer of zinc through electroplating or hot-dip plating. The electroplating method uses the principle of electrolysis to deposit the zinc layer, while hot-dip plating immerses the bracket in molten zinc liquid to make the zinc layer firmly adhere.

Features and advantages
Excellent anti-corrosion performance: The zinc layer forms a dense oxide film in the air, which effectively prevents the erosion of air and moisture, and can maintain stable performance even in a humid environment.
Bright appearance: The silver-white zinc layer not only protects the bracket, but also gives it a simple and beautiful decorative effect.
Typical application
Widely used in headlight mounting brackets of ordinary models, especially vehicles that need to take into account both anti-corrosion ability and cost control.

2. Chrome plating
Process principle
A layer of chromium is deposited on the surface of the bracket through an electroplating process. The process is carried out in an electrolyte containing chromic anhydride, and the chromium ions are reduced by electric current to form a high-hardness chrome plating layer.

Features and advantages
High hardness and wear resistance: It can resist tool friction and external vibration during installation and adjustment, and is not easy to scratch.
Mirror gloss: The surface is as bright as a mirror, which enhances the texture and refinement of the overall vehicle.
Corrosion resistance: It effectively prevents the bracket from rusting and prolongs its service life.
Typical applications
Applicable to high-end models such as luxury cars and sports cars, meeting vehicles with high requirements for both appearance and performance.

3. Painting treatment
Process principle
After the paint is evenly sprayed on the surface of the bracket, it is dried and cured to form a paint film. There are various types of paint, including epoxy paint, polyurethane paint, etc.

Features and advantages
Customized appearance: The paint color can be adjusted according to the vehicle theme or body color to achieve personalized design.
Anti-corrosion protection: The paint layer isolates air and moisture from contacting the bracket, reducing the risk of corrosion.
Typical applications
Mostly used in customized or concept models, especially vehicles that require specific color matching.

4. Powder coating
Process principle
The powder coating is adsorbed on the surface of the bracket by electrostatic spraying technology, and the coating is formed after high-temperature baking and curing.

Features and advantages
Excellent environmental performance: low VOC emissions, in line with modern environmental standards.
The coating is strong and durable: strong adhesion, wear resistance, impact resistance, and not easy to fall off.
Diverse choices: meet a variety of design needs through coatings of different colors or effects.
Typical applications
Suitable for vehicle manufacturers that require environmental protection and high-performance coatings.
