ABSTRACT:
An apparatus for forming an extruded cylindrical closed-ended metal tube having a flat end wall and an integrally formed projection on the end wall includes a die having a recess formed therein, the die having a configuration which corresponds to the terminal end portion of the desired tube and including a cavity which corresponds to the desired projection. The apparatus further includes a punch which is receivable in the die, and includes an end wall having a peripheral portion which extends angularly outwardly at an angle of between approximately 10.degree. and 20.degree. relative to a plane which is perpendicular to the longitudinal axis of the die. The apparatus is operative by placing an extrudable metal disc in the recess in the die and advancing the punch into the recess with sufficient force to extrude metal from the disc into the cavity and also between the punch and the die to form the desired tube.
