Metal spinning: What, why and how

Whenever you need to have custom metal tools and equipment made for whatever purpose, check out the website for access to a provider of metal spinning services and products.

Using a modern CNC machinery, tool making and production equipment, a facility can form a flat sheet of metal into an object or item that can be used for practical functions.

Metal spinning is a process of forming metal into the desired shape either through hot or cold spinning. To make a cone or round shape, for example, flat sheet metal is cut into a disk and then shaped over a rotating mandrel.

Check out the video on the homepage of Metal 4 U for a glimpse of metal spun into something else.

Through this process, a lot of metal products can be created.

Metal spinning versus stamping

Metal stamping is another manufacturing process of forming flat metal sheets into specific shapes. It uses several techniques, including punching, blanking, piercing, and bending. Stamping is also called pressing.

Between spinning and stamping, the former has some advantages.

Low-cost tooling

The tools used in metal spinning is 10 to 20 times cheaper than those used for stamping. Also, the tools and parts needed to form metals can be available within weeks instead of months. This effectively shortens lead times.


In the manufacturing industry, new products are likely to be modified until perfected. Old products, on the other hand, are improved as new innovations come in. This often means modifying the tools used to form metal products.

This is easier achieved with metal spinning tools, as they can be easily redesigned. If there’s a need for a new tool, creating a new one is quicker.

This makes spinning more flexible than stamping and with the least risk.

Better supply chain

Because of shorter lead times and flexibility, there’s no need to limit the number of orders for metalwork. Unless the quantity required is less. This makes it easier to control inventory and meet demands.

Moreover, metal spinning has no twist or spring-back. It is also more environment-friendly because waste is kept to a minimum and the process has lesser emission.

Spinning is not perfect, however. It has its shares of drawbacks too.

  • Requires new tooling for parts that require bigger changes
  • Confined to concentric shapes
  • Thickness of the finished material is not guaranteed
  • Thinning of material may occur
  • Applications of metal spinning

Drawbacks aside, this process can be used to produce items with conical (cone-shaped), cylindrical, hemispherical (half of a sphere), parabolic (bell/dished shaped), toroidal (doughnut-shaped), and venturi (hourglass-shaped) forms.
