We are experts in Spin Forming (also known as metal spinning), a highly efficient technique for producing monolithic metal parts from flat blanks. As an ISO 9001 certified OEM supplier, HS Metal Spinning uses multi-axis CNC technology to guarantee exceptional structural integrity, sub-millimeter tolerances, and material savings. We apply spin forming for critical applications in aerospace, HVAC, and industrial pressure containment.

As your strategic Original Equipment Manufacturing (OEM) partner, HS Metal Spinning is dedicated to precision Spin Forming. This technique, a core competency of our factory, involves applying force to a rotating metal blank (preform) over a mandrel (tool) to gradually shape the metal into an axially symmetric hollow part. Spin forming excels at creating complex, deep-drawn shapes—such as cones, hemispheres, venturi inlets, and specialized enclosures—with superior material flow and integrity compared to drawing or stamping. We expertly utilize this method with materials including Stainless Steel, Aluminum, Carbon Steel, and High-Nickel Alloys, ensuring optimal quality for aerospace, industrial, and high-pressure applications.
Choosing spin forming over alternative methods provides critical technical, structural, and economic benefits:
Spin forming creates a seamless, jointless component from a single sheet of metal. This cold-working process increases the yield strength of the material and results in a monolithic structure that eliminates the stress risers and leak paths inherent in welded or segmented assemblies.
Unlike deep drawing, which often results in severe thinning in the corners and walls, precision spin forming allows for careful control over material displacement. Our CNC process ensures uniform wall thickness throughout the component, which is critical for pressure vessel design and structural consistency.
Spin forming utilizes simple, lathe-mounted mandrels, which are significantly less expensive to design and manufacture than the high-tonnage die sets required for stamping. This makes spin forming the most cost-effective solution for prototyping, engineering changes, and low-to-medium volume production runs.
Spin forming can achieve extreme depth-to-diameter ratios and complex profiles (like compound curves or bell mouths) in a single operation, which would be impossible or prohibitively expensive using stamping or deep drawing.
Operating as a premier source for Spin Forming requires a highly controlled, digital workflow focused on material properties and geometric accuracy:
We analyze the component's geometry and application to select the optimal alloy and tailor the spin path (tool velocity and pressure) to maximize material ductility and prevent tearing or wrinkling during forming.
A precision mandrel is mounted to our multi-axis CNC spinning lathe. The mandrel's contour defines the internal shape of the final component, ensuring perfect rotational symmetry.
The metal blank is centered and rotated at high speed. CNC-controlled rollers gradually apply localized pressure to the blank, incrementally forcing the metal onto the mandrel across multiple passes.
While still mounted on the machine, the spun component undergoes integrated secondary operations, including coordinate trimming of excess material, edge beading, and pre-weld beveling.
The finished component is inspected using CMM to verify critical dimensions, wall thickness, and symmetry against the blueprint. Full Material Test Reports (MTRs) are provided for batch traceability.
We routinely spin form all ductile metals, including 1000- and 3000-series Aluminum, various grades of Stainless Steel (304, 316), Carbon Steel, Copper, and more specialized alloys like Inconel and Brass.
Yes. On the overall diameter and straight flange, we hold tolerances down to 0.2 mm. For critical interfaces requiring higher precision, we utilize integrated secondary CNC machining.
Spin forming is significantly more cost-effective for large diameters and heavy gauges. Hydroforming uses fluid pressure and is typically better suited for lower volumes of complex, asymmetrical shapes with relatively thin walls.
