A method for making a game racket includes two molds having a mold cavity for receiving an annular rib and a network engaged between the molds and engaged with the annular rib. A material is injected into the mold cavity of the molds for forming the annular frame of the game racket and for forming the annular rib in the annular frame and for allowing the network to be secured to the annular frame without threading operation. The annular rib has one or more holes for engaging with the material and for allowing the annular rib to be solidly secured in the annular frame.

Method for making game racket

A game racket includes an annular frame and a tube secured to the annular frame. An annular rib is engaged in the annular frame, and a network has a peripheral portion engaged with the annular rib and engaged in the annular frame for allowing the network to be secured to the annular frame without threading operation. The game racket may thus be made quickly and the manufacturing cost may thus be greatly decreased. The annular rib has one or more holes for engaging with the plastic material and for allowing the annular rib to be solidly secured in the annular frame.
