ABSTRACT:
A bowling pin including a body having a head, a neck, a ball line portion, and a base all integrally formed of a synthetic material. The body includes a hollow area and a longitudinal axis of the hollow area extends generally perpendicularly to a substantially planar bottom surface of the base. A method of manufacturing a bowling pin includes providing a mold shell having a mold cavity shaped substantially as a bowling pin, disposing a mandrel inside a mold cavity, introducing material into the mold cavity, cooling the material inside the mold cavity, removing the mandrel from the mold cavity, removing the material from the mold cavity, and cooling the material outside the mold cavity.
