Aluminum Spun Domes Overview


Achieve structural integrity and striking aesthetics with Aluminum Spun Domes from HS Metal Spinning. We specialize in forming seamless, high-strength hemispherical, ellipsoidal, and parabolic domes for a variety of critical applications. Our advanced CNC spinning process guarantees precise geometry, uniform wall thickness, and a flawless finish, making us the trusted OEM partner for architectural, industrial, and aerospace components.


Advantages of Our Aluminum Spun Domes Products


The use of Aluminum Spun Domes provides unique engineering and design benefits, especially when large, seamless, symmetrical forms are required.

Monolithic, Seamless Strength

Unlike fabrication methods that involve welding multiple sections, Aluminum Spun Domes are formed from a single piece. This eliminates weak points, enhances structural integrity under pressure or vacuum, and provides a clean, elegant aesthetic.


Lightweight and Corrosion Resistant

Aluminum's low density ensures the dome adds minimal weight to the overall structure, a critical benefit for aerospace and rooftop applications. The material's natural corrosion resistance also ensures long-term durability in outdoor or harsh environments.


Precision and Symmetrical Geometry

The spinning process is inherently designed for creating perfect rotational symmetry. Our CNC-controlled equipment guarantees the precise curvature, diameter, and depth required for critical functions, such as pressure vessel ends or fluid storage tanks.


Versatile Application in Various Sizes

From small instrument covers to massive architectural elements, our Aluminum Spun Domes can be scaled to various sizes. This versatility is due to the adaptable nature of spinning tooling compared to expensive, fixed-size dies.


Our Aluminum Spun Domes Technological Process


The manufacturing of an Aluminum Spun Dome is a high-precision process that guarantees geometric perfection and material integrity.

1. Structural and DFM Review

We meticulously analyze your dome design, focusing on wall thickness requirements, pressure ratings, and mounting features. Our engineers conduct a detailed Design-for-Manufacture (DFM) analysis to optimize the curvature for stability.


2. Specialized Tooling and Programming

Mandrels are fabricated to the precise inner contour of your dome. CNC programs are written to execute a powerful, yet controlled, forming path, gradually shaping the aluminum blank without overstressing the material.


3. Automated Precision Spinning

Using our large-capacity CNC lathes, the aluminum is gradually formed. This highly controlled process is essential for achieving the uniform wall thickness and seamless, accurate radius critical to all Aluminum Spun Domes.


4. Integrated Fabrication and Trimming

Post-spinning, we perform precise in-house operations such as trimming, flanging, or the addition of custom penetrations (holes, ports), ensuring the final product is ready for assembly.


5. Quality Assurance and Inspection

Every Aluminum Spun Dome undergoes a stringent dimensional and structural inspection using specialized metrology equipment to verify the precise curvature, height, and diameter against your specifications.

FAQs about Aluminum Spun Domes


What is the maximum size for your Aluminum Spun Domes?

Our specialized large-capacity CNC lathes can accommodate aluminum blanks, allowing us to produce domes up to 10 feet in diameter. Please submit your exact size specifications for confirmation.


Can Aluminum Spun Domes be used for ASME code vessels?

The spinning process is an ideal method for manufacturing pressure vessel heads. While we produce the dome to your specifications, final certification to ASME code requires testing and sign-off by a qualified engineer.


Do you offer internal coatings for fluid management domes?

Yes. While the spinning and fabrication are done in-house, we manage specialized external and internal protective coatings, such as epoxy or tank liners, through our network of certified partners.
