Precision Craftsmanship: Engineered for Signal Integrity and Premium Feel

This wireless charging case is designed for high-performance and sophisticated aesthetics, balancing the need for robust protection and crucial wireless charging efficiency. It achieves a high-end, tactile finish through the strategic use of Flat Surface Brushing and Bright Anodizing.

1. Flat Surface Brushing (Ergonomics and Heat Management)

For a device frequently touched and requiring stable thermal performance, the brushed texture is functionally vital:

• High-End Industrial Texture: The casing undergoes precise automated brushing to create a perfectly uniform, unidirectional hairline finish across its flat surfaces. This texture provides a distinguished, professional appearance that resists fingerprints and minor surface wear.

• Optimized for Wireless Function: The aesthetic finish must not interfere with the internal coil or charging signal. The brushing process is kept ultra-shallow, ensuring the aluminum's structural integrity and electromagnetic properties remain uncompromised, allowing for efficient wireless power transfer (WPT).

• Passive Thermal Control: The high thermal conductivity of the aluminum alloy (e.g., 6061) is enhanced by the increased surface area from the brushing. This aids in rapidly dissipating heat generated during the inductive charging cycle, protecting the internal components (batteries, chips) from thermal stress.

2. Bright Anodizing (Durability and Aesthetic Brilliance)

The final anodizing sequence seals the sophisticated texture and provides the necessary protection for a long-life product:

• Vibrant, Saturated Color: A light chemical pre-treatment is used to prepare the brushed surface for Bright Anodizing. This process ensures the resulting Type II oxide layer is durable and allows the underlying brushed texture to reflect light in a way that gives the color extraordinary depth and saturation.

• Protection from Daily Wear: The hard, dense anodized layer provides crucial scratch and abrasion resistance, ensuring the wireless case maintains its premium look even when carried in pockets or bags with keys and other objects.

• Non-Conductive Shield: Anodizing creates a non-conductive surface layer, which is essential for external safety and prevents unwanted electrical shorting while maintaining the overall shielding effectiveness of the aluminum casing.

The coboggi.com Solution: Integrating Aesthetics with Electrical Performance

At Aile Precision Hardware (coboggi.com), we specialize in enclosures where electromagnetic integrity, thermal performance, and premium aesthetics must coexist. Our OEM/ODM service manages the delicate constraints of wireless charging devices.

A. Mastering Complex Manufacturing (The "How")

We manage the specialized process flow required for high-performance wireless charging products:

1. Wireless Signal Clearance: The initial CNC machining is programmed to maintain precise, ultra-thin wall thicknesses (often 1mm) in the coil area. The brushing and anodizing processes are monitored meticulously to ensure they do not compromise this critical wall thickness, which would reduce charging efficiency.

2. Texture Uniformity and Branding: Automated brushing systems guarantee that the hairline texture is perfectly parallel and uniform across the entire casing, reflecting a consistent brand image. Logo and text may be added via post-anodizing laser marking for maximum contrast.

3. Tolerance for Sealing: We guarantee the precision of interlocking pieces (0.01 mm tolerance) to ensure a snug, dust-resistant seal around the internal components, crucial for device longevity.

B. Customization and Scalability (The "Why")

• Thermal-Aesthetic Balance: We consult on the optimal brush texture and aluminum alloy (e.g., using 6061 for higher thermal transfer) to meet both the client's aesthetic goals and the required thermal ceiling during charging.

• Custom Color and SKU Differentiation: Our Bright Anodizing offers a full palette for product differentiation, allowing different models or tiers (e.g., standard vs. fast charge) to be visually distinguished by color while retaining the premium brushed texture.

• High-Volume Production: Our vertically integrated manufacturing process—from precision machining to the final surface treatment—ensures a reliable, scalable supply chain capable of delivering high-volume orders with consistent quality and competitive cost-effectiveness.
