What Metal Spinning Does

Metal spinning forms flat metal discs or preforms into axisymmetric, hollow shapes by rotating the material and shaping it over a mandrel using controlled pressure. The process gradually deforms the material into the desired geometry without removing material, maintaining a continuous structure.
Because the material is formed rather than cut, metal spinning can produce parts with smooth contours, uniform wall thickness, and good structural strength, especially for round or conical shapes. It is well-suited for components that require both functional performance and clean visual appearance.
Metal spinning is particularly effective for parts such as cones, domes, cylinders, and curved profiles, where alternative methods would require multiple forming steps or welding. It allows designs to be realized as a single piece, reducing joints and improving overall integrity.
Compared to stamping or fabrication, metal spinning offers greater flexibility for medium volumes and complex curved geometries, with lower tooling cost and the ability to adjust designs more easily.

Specifications

Materials Suitable for Metal Spinning Process:

	Key Characteristics	Typical Applications
Carbon Steel	High strength, low cost. Suitable for high-volume production.	Lampshades, cookware, pressure vessels, aerospace housings.
Stainless Steel	Corrosion resistant, bright appearance. More difficult to spin, requires multiple passes or heating.	Food equipment, sinks, exhaust system components.
Aluminum Alloy	Most common, excellent spinning performance. Lightweight, corrosion resistant, good ductility.	Beverage cans, phone/laptop enclosures, automotive panels, heat sinks.
Copper Alloys	Good ductility, excellent thermal/electrical conductivity. Pure copper work-hardens easily; brass has better plasticity.	Copper hot pots, lighting fixtures, musical instruments, heat sinks.
Titanium Alloys	High strength, lightweight. Requires hot spinning (with heating).	Aerospace structural parts, medical implants.
