Tests are reported into the bulging of copper tubes by internal pressurisation within a closed die, using urethane rods of different hardnesses and under different conditions of lubrication. The component explored was 'bottle shaped', the 'neck' being the original diameter of the tube, i.e., 38.1 mm

Using an empirical friction characteristic for urethane under pressure, an approximate theory for determining the initial yield pressure and the final forming pressure needed on an internal urethane rod to bulge a tube is put forward. The results of experimental investigations agree well with the th
