Product Parameter

Product Name Aluminum Alloy Card Reader Shell

Product Material Aluminum Alloy

Processing Technology Precision CNC Processing

Surface Treatment Anodizing

Customization Service Supports drawing customization, sample reproduction, and special function requirement development

Product Feature And Application

Ultra-precision card slot adaptation

CNC processing ensures that the SD/TF card slot tolerance is ≤±0.01mm, plugging and unplugging is smooth and not stuck, and is compatible with UHS-II high-speed transmission requirements.

High-speed and stable transmission

The aluminum alloy shell is naturally resistant to electromagnetic interference, reduces signal attenuation, and ensures the stability of USB 3.2 Gen2 (10Gbps) data transmission.

Efficient heat dissipation design

Through the heat dissipation holes + internal heat conduction structure, the heat of the main control chip is quickly exported to avoid long-term reading and writing speed reduction.

Military-grade durability

The 7075 aluminum alloy has high hardness, anti-fall and anti-deformation, and the surface anodized layer is scratch-resistant and anti-fingerprint, which can adapt to harsh industrial environments.

Personalized appearance customization

Supports multi-color anodizing, gradient laser engraving, hollow indicator light opening and other processes to meet the aesthetic needs of consumer electronics and industrial equipment.

Application scenarios 

Photographic equipment: high-speed card reader, meeting the needs of real-time export of 4K/8K video.

Industrial data acquisition: anti-electromagnetic interference design, adapted to factory automation equipment data storage.

Security monitoring system: IP67 protection + wide temperature tolerance (-20℃~70℃), suitable for long-term outdoor use. Business office peripherals: ultra-thin design + Type-C interface, portable and compatible with laptops/tablets.

E-sports storage expansion: RGB lighting effect customization, enhancing the technological sense and brand recognition of the device.

FAQ 

Q: Does the aluminum alloy shell affect the card reader signal?

A: No! We optimize the opening position and grounding design to ensure the complete transmission of high-frequency signals and pass the FCC certification test.

Q: Can it support multiple cards to read and write at the same time?

A: Yes! The independent compartment structure of multiple card slots can be customized to avoid electromagnetic interference between cards and is compatible with SD+TF dual cards in parallel.

Q: What information is required for customization?

A: 3D drawings (STEP format), card slot type/position table, and interface specifications are required. If there is no design draft, sample mapping service can be provided.

Q: Does it support waterproof design?

A: Yes! IP67/IP68 waterproof shell can be customized.
