The present invention relates to the technical field of refrigerator frames, and specifically discloses a coating-free high-strength refrigerator frame and a processing process thereof. In the present invention, isobornyl groups are introduced onto the surfaces of polytetrafluoroethylene and glass fibers to improve the cold resistance of the coating-free composite material. Using styrene-maleimide as a compatibilizer for ABS and polyamide 66, ABS, modified polytetrafluoroethylene, styrene-maleimide, polyamide 66, modified glass fibers, antioxidant 1010 and pigment are uniformly mixed to obtain a coating-free composition, which is extruded by a twin-screw extruder to obtain a coating-free composite material, then injection molded to obtain a semi-finished refrigerator frame, and finally the edges are trimmed and burrs are removed to obtain the coating-free refrigerator frame.
