The invention relates to a method for manufacturing badminton pinnae, which at least comprises the steps of paving material, gluing, die machining and obtaining a semi-finished product, wherein in the step of paving material, a material is divided into an upper framework and a lower framework which are opposite and pulled simultaneously, and the lower framework is subjected to gluing; in the stepof gluing, one surface, opposite to the upper framework, of the lower framework is subjected to the gluing by using a brushing device before the die machining, so that the upper framework can be bonded mutually with the lower framework subjected to the gluing; in the step of die machining, the upper framework and the lower framework are pulled to the middle of two opposite dies, and a plastic finished product is arranged above the lower framework in the dies, so that the plastic finished product can be pressed into the semi-finished product through the dies; and in the step of obtaining semi-finished product, after the die machining, the pinnae are arranged at one end of a branch bar of the plastic finished product. In the method, the artificial pinnae are arranged at one end of the branch bar to replace natural feather wings of the conventional badminton, so the manufacturing speed of the badminton is accelerated, and the cost is reduced greatly.
