ABSTRACT:
A process of molding a racket frame having an evacuation stage for shrinking a lamination of an inner bladder, a tubular prepreg and an outer protective tube before closing a mold, and the reinforcing fibers of the prepreg are not cut by inner edges of the mold, thereby preventing the racket frame from burr due to the reinforcing fibers cut by the inner edges.
