Some experimental and theoretical results are presented for the dieless drawing method. Because of the absence of a rigid die considerable flexibility is reached by this method. For example it is possible to achieve very high strains in one pass. Unlike in conventional drawing it is possible to produce parts with variable cross‐sections along the length by varying the drawing velocity appropriately. This is demonstrated theoretically and experimentally. To model this process a simple one‐dimensional disk model is suggested. The resultant temperature distribution is compared with previous calculations.
