Forming A Cone From Sheet Metal

View the cone instructions below to learn how to manually layout the flat pattern for a truncated cone in single or multiple gore sections.

Forming a cone from sheet metal.

You can find cone calculators online. It allows you to determine either the size of raw material needed or the number of gore sections to fit on your available material. Sheet metal cone calculator. The applied force stresses the metal beyond its yield strength causing the material to plastically deform but not to fail.

Here is one way to make a cone from flat stock. Light weight sheet metal cones are often used in metal duct work in ventilation systems and cones made from heavy plate are used in metal duct work for steel mills and other large manufacturing applications. Sheet metal forming processes are those in which force is applied to a piece of sheet metal to modify its geometry rather than remove any material. 3 pinch rolls of various sizes and roll diameters allows rolling of cylinders and cones.

I used aluminum sheet coil but you could use paper or any flat material. By doing so the sheet can be bent or stretched into a variety of complex shapes. Forming custom metal cones.
