Comprehensive Surface Treatment Services at Smart Vietnam

Whether your requirements involve corrosion resistance, hardness, or abrasion resistance, our surface treatments are specifically designed to meet your unique needs. With a steadfast commitment to quality and efficiency, Smart Vietnam is the perfect partner for all your sheet metal surface treatment requirements.

1. Aluminum Anodizing

Anodizing is a surface treatment process that provides aluminum with exceptional corrosion resistance and various functional properties, depending on the type of anodizing employed. At Smart Vietnam, we offer two primary types of aluminum anodizing:

Hard Anodizing in Sulfuric Acid

Hard anodizing creates a durable, non-conductive layer on aluminum and its alloys, ranging from 5 to 100 µm in thickness. This process significantly enhances hardness and abrasion resistance. Additionally, we provide options for E0 or E6 staining, which result in a matte appearance, as well as black coloring and sealing.

Natural Anodizing in Sulfuric Acid (Decorative)

Natural anodizing produces colorless, transparent layers on aluminum and its alloys, with a thickness ranging from 10 to 25 µm. This type of anodizing is suitable for decorative applications and can be combined with black coloring. The anodized layer is sealed in demineralized water with a specialized sealing additive.

Properties and Color Treatments

The choice of anodic oxidation technique determines the properties and appearance of the surface layer. Hard anodizing forms a robust, non-conductive layer with high resistance to mechanical damage. The resulting color varies based on the alloy used and the layer thickness, offering shades of brown, olive green, and dark gray.

Natural anodizing in sulfuric acid creates transparent, non-conductive layers suitable for decorative purposes. Both hard and natural anodizing processes can be combined with black coloring. Anodizing in chromic acid is particularly useful in industries such as aviation and military due to its high corrosion resistance. The resulting layers are light gray and serve as an excellent base for subsequent painting. At Smart Vietnam, we offer anodizing services for a wide range of aluminum alloys, tailored to meet specific requirements.

2. Zinc Coating

Our galvanic zinc coating process provides excellent corrosion protection by forming a protective layer on the surface of sheet metal products. The zinc layer is passivated with blue or yellow passivation, without the use of Cr6+, to further enhance its corrosion resistance.

3. Nickel Coating

Through galvanic nickel coating, we create a high-gloss and hard layer on sheet metal products. This technique is suitable for achieving decorative finishes or functional coatings that demand superior corrosion resistance and mechanical wear resistance.

4. Tinning

With glossy tinning, we apply a highly glossy tin layer onto sheet metal products made of iron, copper, and copper alloys. The tin layer enhances corrosion resistance, improves solderability, and enhances electrical conductivity, making it an excellent choice for applications in the food industry.

5. Blackening

Our blackening technique is primarily used as a decorative surface treatment for steel components. It creates a thin, black oxidation layer that adds aesthetic appeal. While the resulting layer offers minimal protective effects, we can apply suitable preservatives to enhance durability.

6. Powder Coating

At Smart Vietnam, we offer comprehensive powder coating services for sheet metal products. Powder coating is a popular surface treatment method that provides a durable, attractive finish while offering excellent protection against corrosion, chemicals, and UV radiation.

7. Electropolishing
Electropolishing is a process that enhances the surface finish of stainless steel products by removing a controlled layer of metal through electrochemical means. It provides a smooth, bright, and clean surface with improved corrosion resistance.

8. Passivation
Passivation is a chemical process used primarily on stainless steel to remove contaminants and enhance the material's corrosion resistance. It involves the application of a passivating agent to create a protective oxide layer on the surface.

9. Chromating
Chromating, also known as chemical conversion coating, is a surface treatment technique that provides corrosion resistance and improves paint adhesion on aluminum and its alloys. It involves the application of a chromate conversion coating, resulting in a protective layer.

10. Phosphating
Phosphating is a surface treatment method that forms a phosphate conversion coating on metal surfaces, typically steel or iron. It enhances corrosion resistance, improves paint adhesion, and provides a suitable base for lubricants or sealants.

11. Silkscreen Printing
Silkscreen printing is a versatile technique used to apply intricate designs, logos, or text onto sheet metal surfaces. It allows for precise color reproduction and customization, making it ideal for branding and product identification purposes.
