What is the production process of tennis?

The production process of tennis can be divided into three steps. The first step is to make a bladder, which involves subjecting the raw rubber to a series of tests and transforming it into a fixed size cylindrical structure. The second step is to place the hemispherical ball bladder into the molding machine for heating, pressure bonding, and continuously polish the cooled complete ball, applying white adhesive. The third step is to put each piece of felt into the machine, so that the felt fully engages with the bladder coated with white adhesive. Finally, after steps such as creating a brand logo, the tennis ball was completed.
