What is the Difference Between Ordinary Metal Spinning and Strong Metal Spinning?

In essence, ordinary metal spinning focuses on creating concave shapes, while strong metal spinning emphasizes thinning and elongating the material.

Ordinary metal spinning, a type of spin forming, primarily alters the shape of the billet with minimal changes to the wall thickness. This process shapes workpieces by adjusting the diameter of the sheet metal, making it a non-cutting forming technique for producing thin-walled rotating parts. It involves rotating a metal disc or preform while a spinning wheel applies pressure to achieve the desired shape.

Strong metal spinning, also known as thinning spinning, evolved from ordinary metal spinning. Unlike ordinary spinning, this process not only changes the shape of the blank but also significantly reduces its wall thickness. The key distinction lies in the fact that thinning spinning falls under the category of volume deformation. During this process, the wall thickness is reduced while the volume of the billet remains largely unchanged. The final shape of the product is determined by the core mold's dimensions, and the accuracy of the finished product depends on the precise control of process parameters. For cylindrical parts, strong metal spinning reduces the outer diameter without altering the inner diameter (or vice versa in internal spinning). This method allows for substantial deformation in a single operation, significantly boosting production efficiency compared to ordinary metal spinning. As a result, its applicability is greatly expanded, though it requires more powerful equipment.

While many factories are capable of ordinary metal spinning, only a few can handle strong metal spinning. Yixing Technology excels in both processes, offering expertise in spin forming for custom metal spinning projects. Contact us for tailored solutions to meet your specific needs.
