Metal spinning

Metal spinning is used to produce various axially symmetrical objects of rotational shape. For example, you can find thermo mugs produced in this way on Rigad.com. However, vases, cups, pots and other dishes, chandeliers, bells or chimney rosettes and reductions, etc. are also created in this way. And this technique is also used, for example, in the automotive industry.

Metal spinning works simply, you just need to attach the mold (model) according to which you want to shape the sheet metal, and then the sheet metal itself (this can be steel, aluminum, brass or copper). The metalworker then presses the sheet metal against the mold using a special tool with a wheel at the end; this way, perfectly formed objects can be created without traces of the production process.

Sheet metal can be shaped manually up to a thickness of approximately 1 millimeter, with thicker sheets forming is more complicated. Sheet metal up to 5 millimeters can be machined on CNC lathes (this applies to aluminum, which is softer and more malleable). In addition to industrial metalworkers, various restorers, artistic craftsmen and painters also work with metal spinning. The reason is also the fact that this method was most widespread during the Art Nouveau period and if a product or even an entire building from this period is being restored today, metal spinning also comes into play.

One of the biggest advantages of metal spinning is the seamless processing of the material – which also means that products created by metal spinning do not have any welds. This is an advantage for the aforementioned thermo mugs, which, without welds, have a much lower risk of manufacturing defects and vacuum leaks.
