Abstract

A major interest regarding electromagnetic forming of metal results from the fact that, unlike all known forming methods, plastic deformation of the material is not produced by physical contact between a punch type tool and the workpiece, the desired shape being obtained by means of magnetic pressure. The main objective of this paper is to analyze the possibility of using electromagnetic forming to manufacture some metal cans for optoelectronic components (photodiodes, phototransistors). The paper presents a finite element model for electromagnetic forming of a TO-39 metal can. Finite element modeling was aimed to establish the main working electromagnetic and mechanical parameters that assure proper forming of the metal can, to help tools designing (coil and mandrel) and to establish relative positioning and fastening mode between workpiece and tools..
