Abstract
A method for constructing a plastic door for a household electrical appliance such as a refrigerator having an outer door shell to which is assembled an inner door liner. The outer shell is formed into a concave dished shape having a continuous side wall. Following forming, the edge of the shell side wall is heated and bent to form a flange extending toward the inner cavity of the shell. Heating and bending of the edge is implemented while maintaining the shell in a mould and acting on the free edge of the side wall. A door outer shell made by this method includes a side wall with the edge of the side wall bent towards the interior of the shell, and when a door liner is secured to the outer shell, the bent continuous edge of the side wall is exposed to view and has an attractive appearance.
