Ball for practice of grasping grasping ball and method for producing the ball

摘要

In the past, the fingers of the ball grasping of the respective balls are printed on the inside of a transparent sphere and sealed and 3D display has been proposed. It was not possible to produce mass production because it took time in the production process to display the fingers by printing and sealing on the inner side of the transparent sphere.Solution: each type of ball is provided with a finger type in which a ball is inserted into the sphere by a convex pin concave hole in the sphere, and the ball type insertion is done in the sphere, and each ball type ball doesn't make the shape of the whole sphere Since only the finger type of each pitcher is made and it is necessary to catch it to the hemispherical body type, the loss of the mold molding cost and the time becomes small, and the manufacturing becomes also easy.Diagram
