Brass Spun Domes Overview


Achieve enduring quality and sophisticated aesthetics with Brass Spun Domes from HS Metal Spinning. We specialize in forming seamless, high-strength domes—including hemispherical, conical, and ellipsoidal shapes—that are vital for both critical industrial enclosures and prominent architectural features. Our advanced CNC spinning process guarantees perfect rotational symmetry, uniform wall thickness, and a flawless surface, making us the trusted OEM partner for components requiring both precision engineering and visual appeal.


Advantages of Our Brass Spun Domes Products


The selection of Brass Spun Domes provides unique advantages where durability, structural integrity, and high-end aesthetics intersect.

Monolithic Structural Integrity

Forming the dome from a single brass blank eliminates welding seams and joints. This monolithic construction is inherently stronger, more symmetrical, and ideal for pressure vessel ends or structurally exposed applications.


Exceptional Corrosion Resistance

Brass, an alloy of copper and zinc, offers superior natural resistance to moisture, corrosion, and tarnish. This makes Brass Spun Domes highly durable for use in marine environments, outdoor installations, and chemical processing equipment.


Versatile Aesthetic Finish

Brass offers a warm, visually rich appearance that can be tailored to specification—from a high-gloss polished finish to a deep, natural patina. The seamless nature of the spun dome enhances the material’s aesthetic purity.


Precision Geometry and Repeatability

Our CNC spinning lathes ensure the exact curvature and dimensions of your dome are replicated with high precision across every piece in your order, crucial for both fit-up and aesthetic consistency.


Our Brass Spun Domes Technological Process


The manufacturing of a high-quality Brass Spun Dome follows a meticulous, quality-controlled workflow:

1. Specification Review & Material Sourcing

We analyze your design specifications for diameter, depth, and wall thickness. The optimal brass alloy is sourced, ensuring certified material properties for your application.


2. Specialized Tooling and CNC Programming

Custom mandrels are precisely fabricated. Our CNC programs are written to execute a controlled, multi-pass tool path that gradually forms the brass without inducing undue stress or hardening.


3. Automated Precision Spinning

The brass blank is powerfully yet gently formed on our advanced CNC lathes. This ensures perfect rotational symmetry, uniform wall thickness, and a seamless, high-fidelity contour—the foundation of a durable Brass Spun Dome.


4. Integrated Finishing and Fabrication

We perform precise in-house secondary operations, including trimming, punching of ports or mounting holes, and preliminary surface preparation (polishing or brushing).


5. Quality Assurance and Inspection

Every finished dome undergoes stringent dimensional inspection using specialized metrology equipment to verify all critical geometric parameters, guaranteeing compliance with structural and aesthetic requirements.

FAQs about Brass Spun Domes


Can Brass Spun Domes be produced for large diameters?

Yes. Our specialized large-capacity CNC lathes can accommodate large brass blanks, allowing us to produce domes of impressive scale for architectural and industrial applications.


What brass alloys do you recommend for Brass Spun Domes?

We commonly use C260 (Cartridge Brass) and C280 (Muntz Metal) for domes due to their excellent formability and finish characteristics. The choice depends on the dome's intended use and required strength.


Do you offer services for applying a protective clear coat or lacquer to the brass dome?

Yes. While the spinning is done in-house, we coordinate all necessary external finishing services, including specialized patination, mirror polishing, and protective lacquering, through our network of certified finishing partners.
