Products Description
Aluminium shield plates are manufactured using pure aluminum or aluminum alloys as the main raw material. Through precision sheet metal processing and special surface treatment, they are made into functional sheet metal parts. Utilizing aluminum's high electrical and thermal conductivity, as well as the electromagnetic shielding principle of metallic conductors, they block electromagnetic radiation. Combined with aluminum's lightweight, corrosion resistance, and formability, they are primarily used in electronics, military, and medical fields. Why choose aluminum for aluminium shield plates? Because aluminum has excellent ductility, it can be processed into complex structures through stamping, bending, and welding. This allows for the design of cavities and shells in various devices. The dense alumina protective film formed on the surface is resistant to atmospheric conditions and weak acid and alkali corrosion. Surface spraying further enhances corrosion resistance. During processing, positioning holes, mounting flanges, and snap-fit structures are pre-drilled, supporting multiple assembly methods and facilitating the inspection and replacement of internal components.
The characteristics of Aluminium Shield plates often stem from their raw materials, primarily focusing on the following aspects:
Electromagnetic Shielding:
Achieves 60~120dB of shielding for traffic, with raw material costs only 1/3 to 1/5 of copper shielding plates, making it the preferred choice for balancing performance and cost.
01
Lightweight Advantage:
Aluminum has a low density, typically only 2.7g/cm³, approximately 1/3 that of steel and 1/3.3 that of copper, making it suitable for weight-sensitive applications such as new energy vehicles, aerospace, and portable electronics.
02
Weather Resistance:
Surface coating treatment ensures resistance to salt spray corrosion for over 480 hours, and it can operate stably in extreme environments ranging from -40℃ to 150℃, supporting various scenarios including indoor, outdoor, and automotive applications.
03
Thermal Conductivity:
Aluminium Shield plates have a thermal conductivity of 237W/(m・K), assisting in equipment heat dissipation while shielding electromagnetic waves, reducing the risk of localized overheating, and making them suitable for the integrated design of high-power electronic components.
04
Customization Services:
Raw materials, thickness, surface treatment, and structure can all be customized, supporting small-batch trial production and large-scale mass production with short delivery cycles.
05
Quality control of aluminium shield plates is the manufacturer's top priority. From raw material intake to processing, from finished product delivery to after-sales service, a traceable control system has been established, focusing on indicators such as shielding performance stability, structural precision consistency, and environmental adaptability.
Raw Material Monitoring: The conductivity of each batch of aluminum is tested, including thickness tolerance, flatness, and mechanical properties, to ensure that the material meets the requirements for electromagnetic shielding and processing. The surface of the sheet material is free of defects such as oxidation, scratches, and pits. The conductivity uniformity deviation is ≤2% IACS to avoid localized attenuation of shielding effectiveness due to material inhomogeneity.
Process Control: The precision and stability of the processing steps directly determine the shielding effectiveness. Key hole tolerances are ≤±0.05mm, bending angle tolerances are ≤±0.3°, and flatness is ≤0.2mm/m, effectively preventing leakage problems. Laser welding and TIG welding are used to check for incomplete welds and porosity. Weld flatness is ≤0.1mm, and the conductive contact resistance at splices is ≤50mΩ to ensure continuous electromagnetic wave conduction. The powder coating thickness is 60~120μm, and the salt spray corrosion resistance is ≥480 hours.
The finished Aluminium Shield plate requires 100% quality inspection, including hole coordinates, bending angles, and flatness, and a detailed inspection report is issued to ensure that dimensional fluctuations are within tolerance.
