In the spinning process sheet metal is formed in a cold process. The raw material is mostly mild steel but higher steel grades can also be used in some cases.
In a rotational process the sheet metal components are spun utilizing tooling formed and shaped for the specific application bringing out the desired shape and measurements.
Using the spinning process, it is possible to manufacture sheet metal components with a higher degree of surface uniformity as compared to machined forged or casted components.
Advantages from spinning
The advantage of producing a sheet metal component using the spinning process as opposed to casting is a much stronger and more homogeneous component. In addition a significant weight reduction of the components is achievable.
Spun sheet metal components have high strength and reduced raw material consumption compared to forged and casted components ensuring a direct reduction in weight.
Another advantage is that due to the homogenous raw material and the rotating spinning process the imbalance of spun sheet metal components is less than for pressed or casted components.
In combination the process spinning, deep drawing and punching makes it possible to make sheet metal components of very high complexity in terms of form, shapes and holes.
Example of components
Typical products from the spinning process are pulleys and idlers for belt transmissions or housings for vibration dampers. The spun sheet metal components are used in applications agricultural machinery, trucks, earthmoving and construction equipment and general engine applications.
Cold forming and spinning – a strong alternative to casted or welded components.
