Ping pong balls are not just hatched from larger, ping pong ball-shaped eggs. They’re built at Double Happiness in Shanghai, China. … Balls are cut by machine, with hot water dripping onto them to avoid cracks. Ball halves are then transferred by hand into gluing stations, with solvent spread evenly on each half.
What more do You need to know?
The two halves are placed together and pressed with a light machine for about 15 seconds. [In the paragraph that follows, it tells you how they bubble off the extra material from being glued.] The balls are then baked in a steam oven to dry, and placed into a rounder (a special drying machine) where they also dry under heat lamps.
Company Names Or Trademark:
The next step involves printing: here’s where design comes in. Rules allow only “decent” designs; no company names or trademarks. Each print gets dipped in paint … Each ball is coated several times with different colors, and lastly covered with at least one coat of transparent varnish for protection against water and scratches. It takes 4-5 to produce enough balls for 10,000 games; each game requires 6 balls.
My article talked about how ping pong balls are made, including the size and shape of them, how varnish is applied to protect against water and scratches, the different colors used in painting, and a little bit on their design. All of this is simply knowledge and not to be copied verbatim, as this is a case study.

Article Background Information: How ping pong balls are made? The process through which they become completed starts with the design. Each print that goes into making them has to go under rules saying that “decent” designs are only allowed; no company names or trademarks are allowed.
Then these prints get dipped in paint before they’re coated multiple times with different colors and then finished off with at least one coat of transparent varnish for protection against water and scratches for protection for use during games or training sessions, depending on what they’re used for.
How Average are Needed?
An average of 3 coats are needed in order to produce a ping pong ball that is consistent in color throughout the entire thing, but 5 coats are usually necessary for indoor use, with outdoor ones needing up to 9 paints.
These balls also have to be tested before they go out on the market. This test is called the JIS-test which consists of 5 parts: weight testing, bounce testing, water soaking, sound testing and finally spinning endurance testing where each ball has to spin at least 3 minutes nonstop without slowing down or getting distorted.
