Leather Basketball

The manufacturing process of any custom basketball, be it regular league basketballs or custom rubber basketballs, is similar to every manufacturer.

Inner bladder
Custom basketball's core is called the inner bladder. Manufacturers use black butyl rubber to create them. This rubber gives the ball the ability to bounce and retains the air. Firstly, flat panels are made by melting butyl rubber. They are then attached to the shape of a ball. A one-inch hole is given in the bladder to install the air filler tube. Manufacturers then inflate the bladder, and if it stays the same for the next 24 hours, it passes the initial testing stage.

Shape the carcass
Round bladders are relatively misshaped. Ball's inside, also called the carcass is specially created to achieve uniformity in shape and size. They wrap polyester and nylon threads around the inner bladder. Threads help you achieve the spherical shape of the ball, preventing it from being misshaped. Higher quality threads improve the performance of the custom basketball. Street balls consist of polyester thread, while professional basketballs are formed with nylon thread.

Crafting the covers for the ball
The covers for the custom basketball are made from a variety of materials. High-quality custom rubber basketball or custom basketballs are covered in high-quality leather. The materials used to craft the covers include synthetic rubber, rubber, or composition. The chosen material is cut into six panels to wrap around the ball. If those panels are leather, they are then stitched around the ball. Other materials like synthetic rubber, rubber, and composition panels are glued. After sealing the panels onto the ball, decals, information, and foil markings are applied by hand. The finished balls are about 29.5 inches in circumference and also weigh between 20-21 ounces. Lastly, the balls are inflated and put aside for 24 hours to inspect their air-retention.

Testing and inspection
Final inspection and testing are necessary for custom basketballs and custom rubber basketballs, despite performing multiple tests during manufacturing to check for air retention. In this inspection, we test the bounce, and we make sure that it bounces to a certain height at a specific inflation pressure. When you drop the ball from 72 inches, it should rebound up to 52 to 56 inches. Other minor details like artwork and decals are tested. Extra glue between the panels is removed. After checking the custom basketball totally, it is packed in a polyethylene bag or boxed in packaging to send out to a distributor.
