Metal Spinning

Hi-Craft’s primary area of expertise is the highly specialized process of Metal Spinning. In metal spinning, a flat metal disc is gradually forced by a roller onto a rotating mandrel, taking the shape of the mandrel. This combination of rotation and force shapes the blank into a cone, hemisphere, tube or other circular or cylindrical shape. Metal spinning remains extremely cost-effective today because it requires inexpensive tooling and can be applied to a wide variety of metals. CNC spin lathes are typically used for spinning large quantities, while, for smaller quantities, hand spinning remains the method of choice.

What are the Advantages of Metal Spinning?

Compared to other methods, Metal Spinning has multiple advantages, including:

  • Traditional designs can be formed as one single, seamless piece
  • Low production costs
  • Versatile control of thicknesses
  • Spun products weigh less (since they do not require thick pieces to weld together)
  • A single set-up can be comprised of several operations
  • Material waste is notably smaller
  • Increased tensile/yield strength and hardness
  • Seamless spun objects can withstand higher internal or external pressure
  • Symmetry around a centerline
  • Modifications to forming parameters and part criteria can be achieved quickly and at a lower cost than other methods
