This Discovery UK segment shows how minerals and other materials are blended into polyester resin to produce the cores of the balls.
In this “How It’s Made” segment produced by Discovery UK, viewers can observe the entire process for manufacturing bowling balls. The narrator explains that production of the sporting product has grown from simple carved wood designs to molded plastics.
To produce the core of a bowling ball – which made off-center to allow the ball to spin – the factory in the video mixes powdered minerals, including silica powder, barites, and limestone, are mixed into a polyester resin. A chemical reaction heats and solidifies the materials inside of a mold to form the core.
