OEM Copper Spun Domes Overview


As your dedicated Original Equipment Manufacturer (OEM) partner, HS Metal Spinning delivers high-performance OEM Copper Spun Domes unmatched in aesthetic prestige, corrosion resistance, and structural integrity. Copper domes, whether intended for grand architectural features or critical industrial enclosures, demand perfect geometric symmetry and seamless construction. Our advanced CNC spinning process guarantees uniform wall thickness, tight dimensional control, and a flawless finish, ensuring every dome meets your exact specification and provides enduring value.


Advantages of Our OEM Copper Spun Domes Products


Partnering with us for OEM Copper Spun Domes provides structural and aesthetic benefits essential for high-quality projects.

Monolithic Structural Integrity

Forming the dome from a single copper blank eliminates the need for welding seams that can compromise strength, thermal uniformity, or aesthetic continuity—vital for both pressure components and visible architectural elements.


Corrosion Resistance and Patina

Copper naturally resists atmospheric corrosion, offering exceptional longevity. As an OEM supplier, we deliver domes that are ready to develop the classic, maintenance-free green-blue patina or receive a protective, high-polish finish.


Tight Tolerance Control for Assembly

Our CNC spinning process ensures every dome shape (hemispherical, conical, elliptical) adheres to strict dimensional tolerances, guaranteeing smooth fit-up and integration with your assembly or mounting structures.


Scalable and Cost-Effective Production

Leveraging the efficiency of spinning, we manage high-volume OEM contracts with lower tooling costs and faster throughput compared to traditional fabrication or stamping methods.


Our OEM Copper Spun Domes Technological Process


The manufacturing of high-quality copper domes follows a structured, precision-focused workflow:

1. Engineering Collaboration & DFM

We analyze your blueprint, optimizing the dome geometry for spinning to ensure perfect structural stability and minimal material waste.


2. Specialized Tooling and CNC Programming

Large, high-precision mandrels are fabricated. Our CNC programs are written to execute a controlled, multi-pass tool path that gradually forms the copper blank, ensuring uniform wall thickness and concentricity.


3. Automated CNC Spinning

The copper blank is formed on our advanced CNC lathes. This automated precision ensures perfect rotational symmetry and a consistent, seamless surface finish across all OEM Copper Spun Domes.


4. Integrated Fabrication and Finishing Prep

We perform precise in-house operations such as trimming, flanging, and custom hole punching. The surface is meticulously prepared for external finishing, such as lacquering or patination.


5. Rigorous Quality Control

Every finished dome undergoes stringent dimensional and visual inspection using advanced metrology to verify all critical geometric parameters, guaranteeing compliance with all OEM specifications.

FAQs about OEM Copper Spun Domes


Do your OEM services include coordinating the application of a patina or protective clear coat?

Yes. While the spinning is done in-house, we efficiently manage all necessary external finishing services, including clear protective lacquering, forced patination, or specialized polishing, through our network of certified architectural finishing partners.


How do you ensure the large copper domes are protected during shipping?

We utilize specialized, custom crating and protective packaging designed specifically to support the curvature and structural integrity of large copper domes, ensuring they arrive on-site in pristine condition.


Can the spun copper domes be integrated with other materials like glass or steel?

Yes. We precisely form the dome's edge, flange, or mounting collar to meet the exact dimensional requirements for seamless integration with adjacent materials and structural components.
