ABSTRACT:
A method for combining a metal racket frame with a hollow grip includes the following steps: prepare a metal racket frame and a hollow grip in advance, fit two free ends of the metal racket frame in the upper end of the hollow of the hollow grip and then place the fitted portion of the metal racket frame and the hollow grip in a matched mold. After the matched mold is closed and combined together, the matched mold and the metal racket frame with the hollow grip are turned upside down, and liquid resin is injected in the interior of the hollow grip. After the liquid resin is solidified, remove the metal racket frame and the hollow grip from the matched mold, thus finishing the metal racket frame and the hollow grip combined integrally and smoothly.
