ABSTRACT:
A mould used for making a racket frame comprises an upper mould piece, a lower mould piece and an intermediate mould piece which cooperate to form a cavity that imparts a racket frame shape with the parting line of the mould pieces lying apart from a plane X-X that passes through stringing holes which will be drilled in the frame formed in the mould, thereby avoiding the performing of the deflashing operation at the portion near the stringing holes and preventing the damage of the fiber reinforcement for the string at that portion.
