Mobile phone LCD aluminum frame type
Mobile phone LCD aluminum frame can be divided into many types according to its design, use and manufacturing process. Here are some common categories and their
characteristics:
1. Classification according to structural design
a. Integrated aluminum frame
Description: The entire aluminum frame consists of a single aluminum alloy piece, which is usually CNC machined or extruded.
Advantages:
High structural strength to provide better protection.
Simple appearance, suitable for high-end models.
Cons:
The manufacturing cost is high and the process is complicated.
b. Split aluminum frame
Description: An aluminum frame consists of multiple parts that are joined together by welding or other means.
Advantages:
High production flexibility, can adjust the design of each part according to demand.
The cost is relatively low and suitable for mass production.
Cons:
Joint points can become structural weaknesses, affecting the overall strength.
2. Classify by surface treatment
Description: An oxide film is formed on the surface of the aluminum frame by anodizing treatment, which increases corrosion and wear resistance and allows dyeing.
Advantages:
Beautiful surface, a variety of colors.
Strong durability, not easy to scratch.
Cons:
The process is more complicated and the cost is higher.
b. Sandblasted aluminum frame
Description: Fine abrasive particles are sprayed onto the surface of the aluminum frame by high-pressure air to produce a matte effect.
Advantages:
Good surface texture, feel comfortable.
The anti-fingerprint effect is better.
Cons:
Compared with anodic oxidation, slightly less durable.
c. Electroplated aluminum frame
Description: Electroplating on the surface of the aluminum frame, such as chrome plating, nickel plating, etc., to enhance aesthetics and functionality.
Advantages:
High-grade appearance, strong metallic luster.
Additional functional properties (e.g. electrical conductivity) can be given.
Cons:
High environmental requirements and high costs.
3. Classify by function
a. Heat-dissipating aluminum frame
Description: The design pays special attention to the heat dissipation performance, and the heat dissipation channel or fin is usually designed inside or on the surface of the aluminum frame.
Advantages:
It helps to improve the heat dissipation efficiency of the device and keep the operating temperature stable.
Prolong the service life of equipment.
Cons:
The design is complicated and the manufacturing cost is high.
b. Electromagnetic shielding type aluminum frame
Description: The use of special materials or designs, with good electromagnetic shielding effect, reduce external interference.
Advantages:
Improve the anti-interference ability of the equipment and guarantee the signal quality.
Especially suitable for equipment with high requirements for electromagnetic environment.
Cons:
Material and process requirements are higher, and costs increase.
4. Classification according to manufacturing process
a. CNC processing aluminum frame
Description: Precision machining with computer numerical control machine tools (CNC) ensures high precision and complex shapes.
Advantages:
High dimensional accuracy, suitable for complex designs.
Good quality consistency.
Cons:
The manufacturing cycle is long and the cost is high.
b. Die-cast aluminum frame
Description: Molten aluminum alloy is injected into a mold by a die casting process.
Advantages:
High production efficiency, suitable for mass production.
The cost is relatively low.
Cons:
The dimensional accuracy and surface finish are slightly lower than CNC machining.
Sum up
Different types of mobile phone LCD aluminum frames have their advantages and disadvantages, and which type to choose depends on the specific application scenario and needs. For example, high-end models may prefer to use integrated, anodized CNC machined aluminum frames for extreme appearance and performance; Mid - and low-end models may use more split, sandblasted die-cast aluminum frames to balance cost and performance.
