As outlined by the International Journal of Engineering Development and Research in their article, “Metal Spinning- Design Consideration and Parameter of Spinning Process and Its Terminology,” metal spinning is a traditional, chip-less process used to form axisymmetrical parts by shaping metal over a rotating mandrel. This versatile technique is essential for producing lightweight, rotationally symmetrical components, including cylinders, cones, domes, and other shapes commonly used in industries like aerospace, automotive, and domestic applications.
Metal spinning includes three main classifications—conventional spinning, shear spinning, and tube spinning—each producing hollow, symmetrical parts with unique wall thickness characteristics. In conventional spinning, the thickness remains consistent, while in shear and tube spinning, it reduces as the process progresses. Shear spinning forms parts in a single step, influenced by the component’s wall angle, whereas tube spinning adjusts thickness based on the workpiece length.
Several specialized types of metal spinning also cater to industry needs. For example, flexible spinning techniques enhance the adaptability of the process, allowing it to produce diverse shapes without a fixed mandrel. Asymmetric spinning extends the method’s capabilities to non-axisymmetrical parts, suitable for complex geometries. Finally, hot spinning applies heat to high-strength materials, reducing forming forces for thicker components, although temperature control remains a challenge.
Metal spinning techniques have evolved to improve quality, repeatability, and efficiency in production. These advancements reduce trial-and-error in the design phase, minimize deformation risks, and enhance product consistency, making metal spinning a reliable, adaptable choice for high-quality, lightweight components across numerous industries.
