As your specialized Original Equipment Manufacturer (OEM), HS Metal Spinning delivers high-precision Spun Hemispheres—the ultimate solution for components requiring maximum structural integrity and spherical geometry. Hemispheres are essential for creating durable pressure vessel ends, high-vacuum chamber domes, mixing bowl bases, and aesthetically perfect architectural features. We expertly form seamless hemispheres from a wide range of materials, including carbon steel, stainless steel, aluminum, and copper. Our advanced CNC spinning process guarantees uniform wall thickness, perfect curvature, and superior metallurgical properties, ensuring reliable, high-performance results.
Utilizing seamlessly spun hemispheres provides significant technical and strategic advantages over welded or stamped components:
Hemispheres formed from a single blank are inherently stronger than segmented or welded designs. The absence of internal seams or stress points makes them ideal for vessel ends and domes operating under high internal pressure or deep vacuum.
The CNC spinning process ensures precise, continuous curvature and perfect rotational symmetry. This is crucial for applications requiring aesthetic excellence (e.g., reflectors, architectural domes) or exact fluid dynamics.
Despite the deep forming required, our precision process guarantees uniform wall thickness, which is critical for predictable stress distribution and meeting stringent industrial code requirements (e.g., ASME).
For high volumes of symmetrical, deep components, spinning offers the most cost-effective and scalable manufacturing method, eliminating the need for expensive, dedicated deep-drawing dies.
Manufacturing high-integrity Spun Hemispheres requires a meticulous, high-force CNC workflow:
We confirm the required material grade and review the blueprint for critical tolerances, especially the straight flange and outer diameter (OD).
Custom spherical mandrels are precisely fabricated. CNC programs are written to execute a controlled tool path that gently forms the metal into a perfect dome, ensuring minimal thinning and avoiding stress concentrations.
The metal blank is formed on our rigid, high-precision CNC lathes. This guarantees perfect rotational symmetry and repeatable, sub-millimeter dimensional accuracy across high-volume production runs.
Components are processed through in-house secondary operations, including precision trimming of the straight flange and preparing the edge with the required weld bevel.
Every hemisphere undergoes stringent dimensional inspection, often using advanced metrology (CMM or laser scanners), to verify perfect curvature, OD, and flange height.
Our high-capacity CNC lathes allow us to spin hemispheres up to several meters in diameter, depending on the material thickness. Please submit your exact diameter specifications for a feasibility review.
We use precision CNC trimming after the spinning process to ensure the straight flange is cut to an exact, uniform height and diameter, and we apply the necessary weld prep for immediate fit-up.
While the forming is done in-house, we coordinate all required external finishing services, including electropolishing (common for UHV and sanitary uses) and passivation, through our network of certified partners.
Our Company HS Metal Spinning has been a dedicated OEM partner since 2014, excelling in high-quality, customized metal forming solutions. We are a trusted manufacturer for sectors requiring precise spherical forms, including pressure vessel fabrication and high-end architecture.
