Abstract
Micro shaped wires are widely used in various applications, such as in connecter terminals for laptop personal computers, mobile phones and building materials. In particular, wires with a round cross section have conventionally been used as orthodontics wires; however, the use of rectangular wires enables more efficient orthodontics treatment because rectangular wires are easier to handle and orthodontics strength is sustainable. In this study, drawing experiments and FEM analyses were carried out by varying the amount of reduction in order to improve the quality and dimensional accuracy for developing Orthodontics wires. We also succeeded in obtaining rectangular wires (0.63mm×0.42mm, R=0.1) by shaped drawing.
