In this article, the influence of a new copper wire processing technology on the equivalent strain change was investigated. This technology consists in the wire deforming in a rotating equal-channel step matrix and subsequent drawing. The matrix rotates around the axis of the wire and thereby creates tension due to equal-channel angular broaching and twisting in the matrix. Deformation modelling was carried out at ambient temperature. To assess the effect of the twisting degree on the strain distribution, the rotation speed of the matrix was changed within 6, 18 and 30 rpm. The distance between the two deforming tools was also changed in the range of 100, 200 and 300 mm. The simulation results showed that an increase in the distance between the tools and the rotation speed of the matrix leads to an increase in the twisting angle and the total accumulated strain.
