The invention discloses a floor socket shell and a production process. The floor socket shell comprises a baseplate and peripheral side plates. The floor socket shell is characterized in that the peripheral side plates are formed by a square tube shaped aluminum alloy section through fixed-length cut-off, and the base plate is fixedly connected to the bottom of the aluminum alloy section. The production process comprises the following steps of (a) carrying out stretch forming on the aluminum alloy section; (b) carrying out fixed-length cut-off on the aluminum alloy section; (c) carrying out die-cutting and blanking on the baseplate, wherein the shape of the base plate is the same as the shape of an outer cross section of the aluminum alloy section; and (d) tightening the baseplate at the bottom of the aluminum alloy section through screws. The floor socket shell has the advantages of simple production process, high-grade and attractive product appearance, light weight, high intensity, corrosion resistance and long service life, and is very beneficial to assembling of internals of a socket, so that the assembling quality is better guaranteed.
