Have you ever looked at a golf ball and wondered what is actually inside it?
It may be one of the smallest pieces of equipment in your golf bag, but a modern golf ball contains an impressive amount of engineering and technology.
Golf balls have also changed enormously over the history of the game. They have evolved from simple wooden balls to carefully engineered, multi-layer designs manufactured to extremely tight tolerances.
So, how are golf balls actually made?
The First Golf Balls
Golf has been played in Scotland for centuries. In fact, the game was famously banned by the Scottish Parliament in 1457 because it was distracting people from practising archery.
The earliest golf balls are generally believed to have been made from wood.
These were very different from the precisely manufactured golf balls we use today, but they were eventually replaced by a much more sophisticated design.
The Featherie Golf Ball
The next major development was the featherie.
These golf balls consisted of a stitched leather pouch that was tightly packed with wet feathers.
As the feathers dried, they expanded while the leather contracted, producing a surprisingly firm and relatively round golf ball.
Producing featheries was extremely labour-intensive. A skilled ball maker could spend hours producing a single ball, making them expensive.
They could also be damaged relatively easily, particularly in wet conditions.
Despite those disadvantages, a well-made featherie offered impressive performance for its time.
The Gutta-Percha Golf Ball
A major change arrived during the 19th century with the introduction of the gutta-percha, commonly known as the guttie.
Gutta-percha could be heated and moulded into shape, making golf balls much easier and cheaper to manufacture than featheries.
Something interesting was also discovered.
Golfers found that older, scratched and marked gutties often flew better than perfectly smooth new ones.
Manufacturers began intentionally adding patterns to the surface of golf balls.
That discovery eventually helped lead to one of the most recognisable features of the modern golf ball:
dimples.
What Are Modern Golf Balls Made From?
Modern golf balls are considerably more sophisticated.
Rather than simply being one solid material, manufacturers can use several different layers to influence characteristics such as:
- Distance
- Ball speed
- Spin
- Feel
- Launch
- Control around the green
Modern balls are commonly described according to the number of pieces or layers used in their construction.
Two-Piece Golf Balls
A typical two-piece golf ball consists of a large rubber-based core surrounded by a durable outer cover.
These balls are generally designed to provide good distance and durability and are popular with recreational golfers.
Three-Piece Golf Balls
A three-piece ball adds another layer between the core and cover.
The additional layer gives manufacturers greater control over the performance characteristics of the ball and can help balance distance, feel and spin.
Four and Five-Piece Golf Balls
More complex golf balls can contain four or even five separate layers.
Each layer can be engineered to behave differently depending on the speed and type of shot being played.
This allows manufacturers to create a ball that produces low spin and high speed from the driver while still providing greater control and spin on shorter shots.
How Are Modern Golf Balls Manufactured?
Although manufacturing methods vary between brands and models, the process generally begins with the core.
1. Making the Core
The centre of a modern golf ball is usually produced from a rubber-based compound.
The ingredients are mixed together before heat and pressure are used to form the material into a spherical core.
The precise formulation of this core is extremely important because it influences characteristics such as compression, speed and feel.
2. Adding the Layers
For multi-piece golf balls, additional mantle layers are formed around the core.
Manufacturers can alter the hardness and properties of each layer to change how the golf ball performs with different clubs and swing speeds.
3. Adding the Cover and Dimples
The outer cover is then formed around the internal construction.
Golf ball covers are commonly made using materials such as urethane or ionomer, depending on the type of performance the manufacturer wants to achieve.
The familiar dimple pattern is formed during the moulding process.
Those dimples aren’t there for appearance. They have a major effect on the aerodynamics of the golf ball, helping it generate lift and reducing aerodynamic drag compared with a completely smooth ball.
4. Finishing and Painting
Once moulding is complete, excess material created during manufacturing is removed.
The golf ball can then be painted and the manufacturer’s logos, model name and alignment markings applied.
A protective clear coating is normally added over the surface.
5. Quality Control
Golf balls must be manufactured extremely consistently.
Manufacturers therefore inspect and test balls to make sure characteristics such as size, weight, construction and performance remain within the required specifications.
Once those checks have been completed, the balls can be packaged ready for sale.
Why Golf Ball Construction Matters
The construction of a golf ball isn’t simply a manufacturing curiosity.
It directly affects how the ball behaves when you hit it.
A golfer looking primarily for distance and durability may prefer a different construction from someone looking for maximum greenside spin and a softer feel.
That’s why choosing a golf ball that suits your game can be more important than simply playing whichever ball happens to be in your bag.
Final Thoughts
The golf ball has undergone an extraordinary transformation.
From wooden balls and leather featheries to today’s multi-layer designs, hundreds of years of experimentation have produced one of the most technologically advanced pieces of equipment in golf.
The next time you put a golf ball on the tee, it’s worth remembering just how much engineering is packed inside that little white ball.
