Abstract

PURPOSE: To improve press efficiency by spot welding two metal plates before pressing.
CONSTITUTION: Sealed casing 2 is formed by pressing simultaneously two iron plates 3 and 3'. Before pressing, flat iron plates 3 and 3' are prefixed by spot welding at two places on the inner side of Part 5 which becomes bottom wall 4 of sealed casing 2 after pressing. Next, prefixed iron plates 3 and 3' are pressed simultaneously so that sealed casing 2 of excellent finish is obtained. Further, iron plates 3 and 3' are fixed at their thickest parts, which become the upper wall or the bottom wall. As a result, it is possible to increase processing efficiency and reduce damages to the metal molds.
