A refrigerator door assembly is mounted on a stationary frame of a refrigeration unit and comprises a door frame integrally molded about a thermo-pane in sealing relationship therewith. The door frame is hingedly mounted on the stationary frame of the refrigeration unit by a pair of upper and lower hinge pins. A torsion bar, integrally molded within the door frame and secured to one of the hinge pins, functions to constantly apply a closing force on the door frame to move the door assembly into sealing contact with the stationary frame of the refrigeration unit.

[ What is claimed is:] [1.] A method for making a refrigerator door assembly adapted to be hingedly mounted on a stationary frame of a refrigeration unit comprising:securing a torsion bar to at least one of an upper and a lower hinge pin;aligning said upper and lower hinge pins vertically and placing them into a mold cavity;injecting a liquified thermoplastic or thermo-setting plastic material into said mold cavity to form a door frame such that said torsion bar is encapsulated within the plastic material composing said door frame and such that at least a portion of said torsion bar is capable of movement relative to said door frame; andcuring and hardening said plastic material to form a structurally integrated refrigerator door assembly.
