Learn How Golf Balls Are Made: Critical to Buying Best Ball
There’s no doubt that the popularity of golf has grown in recent years. Have you ever wondered how golf balls are made? Let’s find out.
The Raw Materials
The raw materials needed in the making of a golf ball are rubber and plastic. Two-piece golf balls come with a strong rubber core complete with a robust thermoplastic, also known as an ionomer resin cover. Three-piece balls comprise a smaller but strong rubber. Sometimes it can have a liquid-filled center complete with a rubber thread wound and balata rubber or ionomer cover.
The Manufacturing Process
The production of three-piece golf balls is a complex activity which will often need over 80 different manufacturing steps and 32 assessments. Making a single three-piece ball may take up to 30 days. Producing two-piece balls requires at least half of the aforementioned steps and can be completed in one day.
Formation of the Center
The interior of the two-piece golf ball is a formed core, a combination of various chemically reactive ingredients. These ingredients produce a compound similar to rubber. After the application of pressure and heat, a core of approximately 3.75 centimeters is formed.
Formation of the Cover and Dimples
Compression, also known as the injection molding process is used in the formation of the dimples and cover, using a two-piece molding, on a two-piece ball. When it comes to injection molding, the core is held inside the mold cavity by pins.
Eventually, molten thermoplastic is inserted in the dimpled cavity that surrounds the core. The application of pressure and hear triggers the cover material to flow through the center and form the dimples and size of the completed ball. When the plastic cools and hardens, the pins are withdrawn and the finished balls removed.
So, why are there dimples in golf balls? Less drag is the simple answer.
About Compression Molding
Compression molding involves injecting molding the cover to form two hollow hemispheres. These are located around the core where they’re heated and finally pressed together with mold.
This combined the core’s cover and forms dimples. Three-piece balls are all-compression molded because the flowing hot plastic is likely to either break sections of the rubber threads of distorting the ball.
Polishing, Painting, and the Final Coating
Rough spots, also known as flash and the seam around the molded cover are removed. Two paint coats are then uniformly applied to the ball. The paint application process involves the use of automatically controlled spray guns.
The ball is then logo stamped. The last step involves the application of a clear coat for scuff resistance and to give the ball a high sheen.
Drying and Packaging
Once the paint is applied, the balls are placed in containers which are then placed in huge dryers. When the drying process is completed, the balls can be packaged either in containers or boxes.
Some Final Thoughts
Golf has been played for many years now. The manufacturing process of the golf ball has continued to evolve over the years. With the advancing technology today, the future of the golf ball can only get better. Here are a few other resources on Golfsquatch for you to review.
