摘要： The hockey puck has a main body portion with opposite parallel surfaces. Ground engaging runners project from each of the opposite base portions of the puck and thus elevate the base surfaces of the puck from the ground to minimize surface contact between the puck and the ground. The ground engaging projections are equally spaced in a circular array at a rim portion of the puck. Openings in the puck concentrate weight at the center and periphery of the puck. The ground engaging projections and the main body portion are formed of different plastic materials, with each plastic selected for the most desirable physical properties and performance characteristics. Thus the ground engaging runners are relatively wear resistant with low ground friction whereas the main body portion is of relatively low hardness and provides the requisite stability and weight to the puck. The puck is formed as a composite of an inner spider mold that forms the ground engaging projections and an overmolded portion that constitutes the main body.
