Production process for PEAK racket

A process of manufacturing a PEAK racket includes the steps of taking a substrate layer, where the substrate layer is adapted to a PEAK racket; cutting a first filling space at a middle of the substrate layer, and filling a low-density material in the first filling space; cutting a second filling space at an upper side of the substrate layer, and filling a high-density material in the second filling space; respectively attaching and fastening a panel on each of two surfaces of the substrate layer, to obtain a semi-finished product; and drilling at a middle of the semi-finished product to form a plurality of through holes that are used for reducing wind resistance, wherein each through hole runs through outer side surfaces of the two panels. There is further provided the step of wrapping an edge of the racket, and mounting a handle.
