RF Shielding: Aluminum housing helps reduce electromagnetic interference in LNA modules and RF amplifier circuits.
Precision CNC Machining: Accurate internal cavities and mounting features help with PCB installation and assembly.
Compact Housing: The 41x39x12mm enclosure is suitable for small RF modules and custom electronic designs.
Flexible Connector Options: SMA connectors, grounding posts, and feedthrough capacitors can be configured as needed.
Custom Manufacturing Available: We can modify existing designs or machine completely new aluminum enclosures based on your drawings.

The HF 41x39x12mm RF shielding box is made from die-cast aluminum with CNC-machined features. It's designed for low-noise amplifiers (LNA), RF power amplifiers, and other RF circuits that need EMI shielding.

Need a different size or a more complex RF enclosure?

At Hofengfab, we manufacture custom CNC machined aluminum housings, from simple RF shielding boxes to complex enclosures with deep pockets, thin walls, angled surfaces, and precision mounting features.

Our machining capabilities include:

3-Axis & 5-Axis CNC Milling: For custom cavities, complex geometries, and multi-face machining.
Precision Drilling & Tapping: Custom mounting holes, threaded holes, and connector openings.
Deep Pocket Machining: Controlled machining of internal cavities and thin-wall structures.
Material Options: Aluminum 6061, 6082, 7075, and other grades upon request.
Surface Finishing: Anodizing, hard anodizing, and other finishes based on application requirements.
Flexible Quantities: Custom prototypes, small batches, and production runs.

Send us your 2D DWG drawings or 3D STEP files for a quotation. We can review your design, discuss machining requirements, and recommend a suitable manufacturing approach.
