This paper studied the pulse generator and conductive device between metal wire and electrode for electroplastic wire drawing. We adopted the powerful GTR module on the design of the pulse generator, which makes a great superiority in the pulse waveform. The experimental results show that the design project is feasible and effective. In this paper, we displayed three types of conductive device between metal wire and electrode. According to the results of the experiments, the advantages and disadvantages of the three types of conductive device were discussed. Moreover, we also discussed the selection principles and methods for electrical parameter during the course of electroplastic drawing. Theoretical analysis and the experimental result indicate that it is advisable to use larger current density as much as possible, while try to decrease pulse width and frequency.
