The invention relates to the field of automobile manufacturing and discloses an integrated type automobile frame and a manufacturing method thereof. The integrated type automobile frame comprises a frame main body. The frame main body comprises a first carling and a second carling which are parallel side by side. A crossbeam part is arranged between the first carling and the second carling. The first carling, the second carling and the crossbeam part are of a metal extrusion integral formed structure. Compared with an existing automobile frame, the integrated type automobile frame is providedwith the first carling, the second carling and the crossbeam part which are arranged in a metal extrusion integral formed mode, independent production machining and assembly forming are not needed anylonger, the structure is simple, and the problems that in the prior art, crossbeams and carlings are produced and machined independently, production machining is complex, and assembly connection precision of the crossbeams and carlings is difficult to ensure are solved.
