1. Function and Characteristics

The basketball is the core equipment used in basketball, with a specific structure and design to meet the needs of competition and training. The design of a basketball aims to provide excellent elasticity and feel, allowing players to accurately pass, dribble, shoot, and perform other actions to win the game.

2. Overall Structure

A basketball is mainly composed of five parts: the inner bladder, winding, middle bladder, outer cover, and the needle. Each part plays an important role in the performance and user experience of the basketball.

① Inner Bladder: Also known as the ball bladder, it is the innermost layer of the basketball, usually made of black rubber. This is the "heart" of the basketball, the main part for inflation, determining the basketball's elasticity and durability.

② Winding: Mid-to-high-end basketballs use this process, while low-end basketballs may not have winding, using gauze instead. The winding material for mid-to-high-end basketballs is special nylon thread. It is evenly wound around the inner bladder, forming a cocoon-like protective layer, enhancing the basketball's durability and stability, while improving the rebound feel and stability during shooting.

③ Middle Bladder: Located between the inner bladder and the outer cover, it is made of rubber. As a supporting structure, it maintains the stable shape of the basketball, preventing the inner bladder from expanding and deforming due to excessive air pressure.

④ Outer Cover: The material of the basketball's outer cover varies. It is the main part of the basketball that comes into contact with the outside world. Its material and craftsmanship directly affect the basketball's feel, durability, and performance.

⑤ Needle: The inflation port of the basketball. As the "throat" for inflating the basketball, it plays a crucial role in the air tightness of the basketball. A high-quality needle design ensures that the basketball does not easily leak air after inflation, maintaining stable air pressure.

3. Price Ranges
