Product Overview
This custom chassis is designed for industrial control units. It showcases a complete sheet metal fabrication workflow: from laser cutting to precision bending and hardware insertion. Unlike standard off-the-shelf boxes, this enclosure is custom-sized to fit the client’s specific PCB layout and thermal requirements.
Manufacturing Process Insight
Laser Cutting
We use fiber laser cutters to achieve clean edges and cut precise ventilation patterns that would be impossible with traditional punching.
CNC Bending
Using high-precision press brakes with automatic angle measurement, we ensure the folded dimensions are accurate to within ±0.2mm.
Hardware Insertion
PEM nuts and standoffs are installed using a hydraulic press, providing strong threads in thin sheet metal.
Powder Coating
The final black powder coat offers a durable, scratch-resistant finish that also provides electrical insulation.
Key Features & Benefits
EMI/RFI Shielding
The aluminum construction provides natural electromagnetic interference shielding for sensitive electronics.
Custom Ventilation
Perforated patterns are designed to maximize airflow directly over hot components.
Lightweight & Strong
Aluminum 5052 offers an excellent strength-to-weight ratio and corrosion resistance.
No Tooling Cost
Unlike stamping, this process requires no expensive molds, making it ideal for low-to-medium volume production (50-5000 units).
