Spin forming, also known as metal spinning, is an advanced manufacturing process that shapes metal sheets into axially symmetrical parts by rotating them at high speeds. This technique utilizes a combination of force and high-speed rotation to form the metal around a mandrel, a type of mold, which shapes the spinning metal into precise, complex geometries.
The precision metal spinning process starts with a flat sheet of metal or tube that is rotated on a CNC or manual spinning lathe, with setups that may include a headstock and follower to handle the diameter and shape of the mandrel effectively. As the metal piece spins, various tools apply pressure to shape the metal into the desired form against the mandrel, utilizing axial strokes to achieve precise dimensions.
This method is highly valued in industrial applications for its ability to produce strong, lightweight components such as pressure vessels, gas cylinders, and fittings with excellent structural integrity. Spin forming is particularly effective for creating parts that require high precision and smooth finishes, making it indispensable in sectors like aerospace, where both the quality and the performance of each component are critical.
In the aerospace industry, dimensional accuracy and consistency are not just desirable—they are essential. Spin forming excels in this regard by providing exceptional control over the dimensions of each part produced.

Ductility, the ability of a metal to deform under tensile stress, is vital in spin forming because it determines how well a material can be shaped into complex parts without cracking. Meanwhile, work hardening, or strain hardening, occurs as the metal is deformed; the material becomes harder and stronger but less ductile. For aerospace applications, selecting materials that balance these characteristics is essential to ensure the durability and integrity of the components under the extreme conditions of aerospace operations. Metals typically used in this process, such as aluminum and titanium alloys, are chosen for their favorable work hardening rates and excellent ductility, which allow for the production of robust yet lightweight parts critical for aerospace structures.

Metal spinning, also known as metal turning, is a specialized manufacturing method that involves a sheet metal-forming technique called metal spinning. The process begins with a flat, round metal blank or disc-shaped workpiece clamped onto a lathe machine. It rotates the blank at high speeds, while a skilled operator uses either hand metal spinning tools like a spoon over a mandrel or hydraulic pressure to shape a blank.
As the lathe spins, an operator employs a mandrel or a roller to apply pressure onto the metal, which is gradually shaped and thinned to achieve the desired thickness and contour. The process creates various complex shapes, such as cones, cylinders, and hemispheres. This allows for greater design flexibility, customization, and the production of complex shapes with precise tolerances that meet the specific requirements of heavy machinery.
