• This chapter provides fundamental background on processes of drawing of rods, wires and tubes. • Mathematical approaches for the calculation of drawing load will be introduced. • Finally drawing defects occurring during the process will be highlighted and its solutions will be included. Suranaree University of Technology Tapany Udomphol Jan-Mar 2007 Introduction : wire drawing • Wire drawing involves reducing the diameter of a rod or wire by passing through a series of drawing dies or plates. • The subsequent drawing die must have smaller bore diameter than the previous drawing die.
