Abstract: A mold for manufacturing an artificial shuttlecock from a semi-finished shuttlecock includes a male mold and a female mold. The male mold includes a cone frustum and a plurality of first annular grooves. The semi-finished shuttlecock is placed on an outside of the cone frustum. The first annular grooves are disposed apart on the outside of the cone frustum. The female mold includes a tapered slot, a plurality of second annular grooves and an injection channel. The second annular grooves are disposed apart on an inner surface of the tapered slot. When the semi-finished shuttlecock and the male mold are placed into the female mold, each of the first annular grooves corresponds to each of the second annular grooves to form a plurality of molded grooves. The injection channel communicates with the second annular grooves, and the molded grooves communicate with the injection channel through the second annular grooves.

Abstract: An artificial shuttlecock, a feather and a preparation method thereof are provided. The feather includes a connecting portion, a first portion, a second portion and a concave. The first portion and the second portion are disposed on the opposite sides of the connecting portion. The concave is located at an outer edge of the second portion. The concave is formed by the following steps of: defining an overlapped outline, which is the outline of the adjacent feather overlapping on the second portion; defining a reference point, which is a point where the overlapped outline is closest to the connecting portion; defining a shifting reference line, which passes through the reference point and is parallel to the connecting portion; defining a reference outline, which is located outside the shifting reference line; and cutting the reference outline to form the concave.
