OEM Sheet Metal Electronic Equipment Housing

Huarui specializes in high-precision aluminum sheet metal fabrication, providing lightweight and high-strength solutions for the robotics, medical, and aerospace industries. We understand the unique challenges of working with aluminum alloys, from managing springback in 6061-T6 to achieving seamless AC-TIG welds without porosity. Our facility is equipped with specialized non-marking bending technology to ensure that aesthetic surfaces remain pristine for Type II/III anodizing or architectural-grade powder coating. Whether you require complex thermal-management enclosures or high-precision internal structural brackets, our engineering team provides the DFM support to ensure your aluminum components are optimized for both performance and cost-efficiency."

Specifications

Why Choose Aluminum for Your Project?

• Lightweight Strength: Aluminum offers a high strength-to-weight ratio, making it the premier choice for Humanoid Robot structures and Drone Chassis.

• Corrosion Resistance: Naturally forms a protective oxide layer, ideal for outdoor and marine applications in Australia and coastal Europe.

• Electrical & Thermal Efficiency: Superior to steel for EV battery enclosures and power distribution boxes.

FAQ

Q: Can you bend 6061-T6 without the material cracking? 

A: Yes. We use specific bend radii and, where necessary, localized annealing or specialized tooling to ensure the structural integrity of 6061-T6 is maintained without surface fracturing.

Q: Is your aluminum RoHS compliant? 

A: Absolutely. All our materials and surface treatments meet RoHS and REACH standards for export to the EU and North American markets.

Q: Can we sign a Non-Disclosure Agreement (NDA) before sharing our designs? 

A: Certainly. We protect the intellectual property of our global clients as a standard practice. You are welcome to send us your company’s NDA, or we can provide our standard agreement for your review.

Q: How do you handle "Design for Manufacturing" (DFM) feedback?

 A: Once we receive your RFQ, our engineers perform a complimentary DFM review. If we identify potential issues—such as a bend radius that might crack or a weld that’s inaccessible—we will provide a detailed report with suggested optimizations to improve quality and reduce costs.

Q: What are your payment terms for international orders? 

A: For new clients, our standard terms are typically a 30%-50% deposit to initiate the order, with the balance due after you approve the final production photos and inspection reports before shipping. For long-term partners with high-volume orders, we are open to discussing more flexible credit terms.
