How It’s Made Ping Pong Balls

Last modified: October 2, 2023


Ping pong balls are essential equipment for the popular game of table tennis. These small, lightweight spheres play a big role in the sport, providing the perfect combination of bounce and control. Have you ever wondered how these ping pong balls are made? In this article, we will take a closer look at the fascinating process behind the production of ping pong balls.

The Manufacturing Process of Ping Pong Balls

1. The materials

Ping pong balls are typically made from celluloid or a similar type of plastic material. Celluloid is a highly flammable substance, so many ping pong ball manufacturers have transitioned to using more environmentally friendly materials. These materials are typically in the form of small resin pellets that are melted down for production.

2. Molding the halves

The manufacturing process begins with the production of two halves of the ping pong ball. These halves are created using injection molding machines. The resin pellets are melted down and injected into a mold that is shaped like half of a ping pong ball. The mold is then cooled, allowing the resin to solidify, after which the halves are removed from the mold.

3. Trimming and smoothing

Once the two halves are removed from the mold, they undergo a process called trimming. Trimming involves removing any excess material or rough edges from the halves to ensure a smooth and uniform surface. The halves are then smoothed by a grinding machine to create a perfect spherical shape.

4. Printing

After the trimming and smoothing process, the ping pong ball halves are ready for printing. The printing process involves applying the desired logos, brand names, or any other artwork onto the surface of the ping pong balls. Special ink is used to ensure that the prints adhere to the smooth surface of the ball.

5. Assembly

Once the printing is complete, the two halves are glued together to form a complete ping pong ball. The glue used is specifically designed to withstand the force and impacts of the game. The ball is carefully assembled to ensure a strong bond between the two halves.

6. Quality control

Ping pong balls undergo strict quality control measures to ensure they meet the required standards. They are tested for weight, size, roundness, and bounce. Only the balls that pass these quality checks are deemed fit for distribution and use in table tennis.

Alternative Materials and Innovations

While celluloid was once the dominant material used in ping pong balls, there have been advancements in the production of table tennis balls. Manufacturers have started exploring alternative materials, such as polyethylene and other plastics, to create more environmentally friendly options. These materials provide similar properties to celluloid, ensuring a consistent and enjoyable playing experience.


The process of manufacturing ping pong balls involves several steps, from melting down resin pellets to molding, trimming, printing, and assembly. Each step is crucial to creating high-quality balls that can withstand the action-packed game of table tennis. As technology advances, we may see further innovations and materials being utilized in the production of ping pong balls, making the sport even more exciting and sustainable. So, next time you play a game of table tennis, take a moment to appreciate the craftsmanship and precision behind the ping pong balls that make the game possible.
