Abstract
A method of forming a refrigerator cabinet includes a step where an external wrapper that defines a rear surface is provided. The rear surface of the external wrapper is deep-drawn to form a machine compartment that defines a top wall, a bottom wall, and an interior wall. An inner liner is positioned within the external wrapper such that a gap is defined between the inner liner and the interior wall of the machine compartment. A vacuum is drawn within the gap.
