In industrial design, the first point of contact is the most critical.

For COBOGGI hardware, the surface finish isn't just a cosmetic final step; it is a functional interface.

A surface that is too smooth lacks grip in high-moisture environments, while a surface too porous becomes a magnet for debris and microbial growth.

Achieving the "Satin-Hard" Balance

We utilize a specific Type III Hard-Coat Anodizing process that creates a micro-textured surface.

Unlike standard decorative anodizing, this electrochemical process changes the cellular structure of the aluminum surface, resulting in a finish that ranks just below diamond on the Mohs scale.

1. The Physics of Grip

By controlling the current density during the anodizing bath, we create a "satin" topography. This micro-texture increases the surface area for friction without the need for aggressive, sharp knurling that could snag on fabric or irritate the skin during prolonged use.

2. Thermal Dissipation & Hand-Feel

The specific porosity of our hard-coat allows for better heat radiation. In portable units like the Subject series, the texture helps break the "boundary layer" of air, assisting slightly in cooling while ensuring the device doesn't feel "sticky" when it reaches peak operating temperatures.

3. Visual Longevity

The finish is non-reflective, which is crucial for professional environments where light glints can interfere with optical sensors or human focus.

Most importantly, it ensures the COBOGGI branding remains a permanent, crisp part of the chassis, resistant to the chemical oils of human skin and environmental abrasion.
