An Evaluation of Spinning vs. Drawing

Spinning versus drawing of metals is evaluated, and it is concluded that each process is logical under certain circumstances. Each is capable of the complete manufacture of products within its scope, and both can be used on some products to good cost advantage. They can complete as well as supplement each other, and whether one or both processes are used depends mainly on the economics of each individual case. The various advantages and disadvantages of both are surveyed critically and in depth. (Formerly 21T8)
