PCT No. PCT/GB96/00710 Sec. 371 Date Dec. 4, 1997 Sec. 102(e) Date Dec. 4, 1997 PCT Filed Mar. 25, 1996 PCT Pub. No. WO96/31299 PCT Pub. Date Oct. 10, 1996Can bodies are formed typically by drawing and wall-ironing a cup, introducing fluid between punch and dies as the cup exits the dies and then forming the desired base profile. The can bodies formed in the present invention are able to be produced from thin hard material such as double reduced steel and/or have stronger base profiles in terms of tighter radii and deeper countersinks than was hitherto possible without risk of splitting.
