Practically any metal that can be worked can be spun. In fact, some metals and shapes are easily spun that cannot be drawn or formed by other methods. Spinning is ideal for applications where there is a demand for absolute structural integrity, a minimum number of components, or a requirement for the use of advanced materials. Metal spinning is an excellent method to consider in conjunction with other forming methods to produce parts and shapes. Due to its simplicity, metal spinning offers many advantages over drop-hammer forming.
Ideal parts are hemispheres, cones, domes, and re-entrant shapes.
Wall thickness is controlled throughout the part, which prevents excessive thinning of the metal. Grooves can also be added either internally or externally to increase stiffness. Aircraft Engine and Nacelle Components Engine cowlings or nose lipskins are manufactured by Sheets Manufacturing Co. using spinning technology to produce a quality part at the lowest price possible. We also manufacture a variety of aircraft engine and nacelle components, including spinners, tail cones, bullet assemblies, pressure seal assemblies and ducting assemblies.
