Purple-Toned Aluminum Mechanical Keyboard Bottom Case: Structural Support & Personalized Base for Custom Keyboards

Introduction

This purple aluminum alloy bottom case is custom-made for mechanical keyboards, crafted from high-strength 6061-T6 aluminum alloy. Offering the strength of metal with a bold, striking purple anodized finish, it brings a unique and personalized touch to your keyboard.

As the "hidden skeleton" of the keyboard, the bottom case serves as the mounting base for core components such as the PCB board, switches, and stabilizers. The precision-engineered slots and screw holes ensure that all components are securely positioned, preventing any loosening from long-term use. Beyond its functional role, the eye-catching purple appearance transforms this bottom case into a key visual element for custom keyboard enthusiasts. It’s the perfect balance of structural stability and personalized aesthetics.

Daily Uses

• Core Component Bearing & Securing: Pre-reserved PCB mounting slots, switch positioning holes, and screw fixtures securely hold mechanical switches, circuit boards, and stabilizer plates in place. This ensures that components remain stable over time, even under frequent use.

• Structural Protection & Deformation Resistance: The high-strength aluminum resists deformation from external pressure or accidental drops, while also shielding internal components from dust and water splashes, which helps extend the keyboard's lifespan.

• Extension of Personalized Style: The vibrant purple anodized finish provides a striking contrast to traditional keyboard colors. It can be paired with custom keycaps and switches, making it the centerpiece of any personalized keyboard build.

•  

• Auxiliary Heat Dissipation: The aluminum construction helps dissipate heat during long periods of use, adding an extra level of comfort for users who spend hours typing or gaming.

Processing Technology Material Preparation: High-quality 6061 aluminum sheets (1.5–2.0mm thick) are chosen to achieve the perfect balance between strength and lightweight properties. CNC Precision Machining: The bottom case is shaped using a 5-axis CNC machine, which cuts the overall contour and mills precise features like PCB mounting slots, screw holes, and positioning buckles. The machining tolerance is ±0.05mm, ensuring a precise fit for all components. Surface Finishing: Sandblasting: High-pressure sandblasting with fine-grained material creates a smooth surface texture, which serves as a base for the vibrant color application. Anodizing: Electrochemical anodizing creates an 8–20μm thick oxide film. This enhances the surface’s wear resistance and fingerprint resistance, while giving the case its striking purple color
