Product Advantage
Exceptional Corrosion & Moisture Resistance: 5052-H32 aluminum alloy’s inherent corrosion resistance, paired with 12-16μm hard anodization, withstands 1000 hours of salt spray testing (ASTM B117). This makes the frame suitable for industrial environments with high humidity or dust, as well as home use where accidental spills (coffee, water) may occur.
Ergonomic Split Design Support: The alloy’s formability enables split ergonomic frames (angle 15°-30°), reducing wrist strain for long-time typists. The split structure allows customization of key spacing, ideal for programmers or users with repetitive strain injury (RSI).
Low-Profile & Space-Saving: For compact setups (e.g., laptop docks), low-profile frames (height ≤7mm) reduce keyboard thickness by 30% vs. standard frames. The slim design fits in backpacks, making it portable for remote work or gaming.
Reduced Key Chatter & Noise: The frame’s rigidity (modulus of elasticity 69GPa) minimizes PCB flex, reducing key chatter (false inputs) by 70%. Rubber gaskets between the frame and PCB further dampen typing noise, making it suitable for quiet office environments.
Cost-Effective Customization: Extrusion technology enables low-cost customization of frame length and cutouts, with MOQ 50 pieces for non-standard sizes. This makes it accessible for small custom keyboard brands or enthusiast groups.

Product Uses
1. Custom Mechanical Keyboards: Split ergonomic aluminum frames with satin anodization are popular among keyboard enthusiasts. The customizable split angle (20°) reduces wrist strain, and compatibility with premium switches (Holy Panda) delivers a premium typing experience.
2. Industrial Control Panels: Bead-blasted aluminum frames integrate with industrial keyboards for factory control systems. The corrosion-resistant surface resists oil and dust, while the rigid structure ensures reliable input in harsh manufacturing environments.
3. Portable Laptop Docks: Low-profile 60% compact frames fit in laptop docks, turning laptops into mechanical keyboard setups. The lightweight design (≤100g) is easy to carry, and the durable frame withstands frequent travel.
4. Quiet Office Keyboards: Rubber-gasketed aluminum frames reduce typing noise to ≤55dB, making them suitable for open-office environments. The moisture-resistant surface also handles accidental coffee spills, ensuring long-term use.
Product Operate Guide
Pre-Assembly Prep: For split frames, confirm the split angle (15°-30°) matches your ergonomic needs. Clean the frame with a dry cloth to remove dust before assembly.
Assembly Steps: Attach rubber gaskets to the frame’s PCB mounting area, then secure the PCB with M2 screws (torque 1.6-2.0N·m). Insert switches and test for key chatter, then install keycaps.
Maintenance: Wipe the frame with a damp cloth to remove spills. For industrial use, clean monthly with compressed air to remove dust from switch cutouts.
FAQ
1. Q: Can the split frame be adjusted to a custom angle?
A: Yes. We offer custom split angles (10°-45°) with a lead time of 7-9 working days and MOQ 100 pieces.
2. Q: Is the frame compatible with hot-swappable PCBs?
A: Yes. The switch cutouts (±0.03mm tolerance) fit hot-swappable sockets (Kailh, Gateron), allowing easy switch replacement without soldering.
3. Q: What’s the lead time for standard 60% compact frames?
A: Standard 60% frames (satin silver/black) ship within 2-4 working days. Custom sizes take 5-7 working days.
