How are Hollow Rubber Balls Made?
Hollow rubber balls are made using a process called injection molding. This process involves injecting molten rubber into a mold, which is then cooled and hardened to form the desired shape. The molds used for this process can be custom-made to create any size or shape of hollow rubber ball.
Steps in the Injection Molding Process
The first step in the injection molding process is to heat up the rubber material until it becomes a liquid. This liquid is then injected into the mold under high pressure. As the rubber cools and hardens, it takes on the shape of the mold. Once cooled, the hollow rubber ball is removed from the mold and inspected for quality.
The next step is to finish off the surface of the ball by sanding or buffing it to give it a smooth finish. Finally, any additional features such as logos or text can be added to customize the ball.
