Abstract
A lower shell for a sealed compressor includes a shape with a plurality of intricate bends. In particular, u-shaped sections are stamped into a plainer sheet of material to form the lower shell. This stamping process can cause brittleness in the lower shell. Thus, after the stamping process, the lower shell is subjected to a heat-treating process to reduce the brittleness. After the heat-treating process a center shell is welded to the lower shell.
