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.
