The production of copper tube with floating plug has been long time, and has realized industrial production. the structure improvement of floating plug is carried out. By using the nonlinear finite element software Marc to simulate the floating plug drawing process. The change trend of drawing force and temperature field before and after improving floating plug are analyzed. The feasibility of floating plug improvement method is verified by simulation. The drawing copper material microstructure before and after the improvement are analyzed respectively. The value of floating plug improvement in industrial production is illustrated from the view of experiment. This study provides a scientific basis for the improvement of the thin wall copper tube in the actual production process of the drawing die with floating plug.
