Corrosion Resistant Sheet Metal Fabrication Parts for Mobile Phone and Computer Cases

Product Description:

Sheet metal products have several key characteristics:

1. Lightweight: Sheet metal is thin, making the products light yet durable.
2. High Strength: Despite being thin, sheet metal offers strong structural integrity and resistance to external forces.
3. Flexibility: It can be easily shaped, cut, and bent into various designs, providing versatility in manufacturing.
4. Cost-Effective: Due to the material's availability and the efficiency of the manufacturing process, sheet metal products are typically affordable.
5. Corrosion Resistance: Depending on the metal used, many sheet metal products are resistant to corrosion, especially when treated or coated.
6. Customizable: Sheet metal can be tailored to specific sizes, shapes, and functions, allowing for custom designs in various industries.
7. Good Thermal Conductivity: Many sheet metal materials, such as aluminum and copper, have excellent thermal conductivity, making them suitable for heat-related applications.

These characteristics make sheet metal products widely used in industries like automotive, aerospace, electronics, and construction.

Advantages of Sheet Metal Fabrication:

Here are five distinct advantages of sheet metal products, different from those previously mentioned:

1. Precision Fabrication: Advanced technologies like laser cutting and CNC machining allow for highly precise and accurate production of sheet metal components, ensuring consistency and tight tolerances in large-scale manufacturing.

2. High Production Speed: Sheet metal fabrication processes, such as stamping or punching, allow for fast mass production, making it suitable for industries with high-volume manufacturing needs.

3. Ease of Assembly: Sheet metal parts can be easily joined through processes like welding, bolting, or riveting, simplifying the assembly of complex structures.

4. Aesthetic Flexibility: Sheet metal can be finished in various ways, including polishing, painting, powder coating, or anodizing, allowing for both functional and aesthetic customization of the final product.

5. Thermal and Electrical Conductivity: Certain metals like copper and aluminum have excellent thermal and electrical conductivity, making sheet metal a preferred material for heat sinks, electrical enclosures, and other heat or electricity-sensitive applications.

Applications:

I. Characteristics of Aluminum

1. Lightweight: Aluminum has a density of only 2.7 g/cm³, about one-third that of steel, making it ideal for products that require weight reduction.

2. Corrosion Resistance: It has excellent oxidation resistance. When exposed to air, a thin layer of aluminum oxide forms on the surface, providing protection against corrosion.

3. Electrical and Thermal Conductivity: While not as conductive as copper, aluminum still offers good electrical and thermal conductivity and is preferred in many applications due to its lightweight.

4. Recyclability: Aluminum is 100% recyclable and retains its properties during the recycling process, making it valuable from both an economic and environmental perspective.

5. Formability: Aluminum is highly ductile and easy to process, allowing it to be stretched, extruded, and rolled into various shapes.

6. Non-Magnetic: Being a non-magnetic metal, aluminum is suitable for use in devices sensitive to magnetism.

Aluminum (Al) is a lightweight, soft, and highly ductile metal that is widely used across various industries.

Characteristics of electrophoresis process:

1. Uniform deposition: Because electrophoresis process depends on the action of electric field, it can make the coating uniformly deposited on the surface of the workpiece to ensure that the coating has no dead angle and no flow hanging phenomenon.

2. high efficiency and energy saving: compared with the traditional coating process, electrophoresis process has higher production efficiency and reduces energy consumption at the same time.

3. Environmental protection and safety: the paint used in electrophoresis process is mostly water-based paint, which has better environmental protection performance, and the whole process is closed, which reduces the emission of harmful gases.

Electrophoresis process:

1. Pre-treatment of workpiece: mainly including oil removal, rust removal, phosphating and other processes to ensure the surface of workpiece is clean and enhance the adhesion of coating.

2. Electrophoresis coating: the coating is applied on the surface of workpiece. The treated workpiece is immersed in the electric field containing electrophoretic coating, and the coating is evenly deposited on the surface of the workpiece through the action of electric charge.

3. Post-treatment: The coated workpiece is subjected to post-treatment such as cleaning and drying to remove excess paint and enhance the weather resistance of the coating.

4. Curing: The workpiece is baked at high temperature to cure the coating and enhance the hardness and corrosion resistance of the coating.
