A Brief History of Golf Balls

The history of golf balls dates back to the 14th century, with the earliest known design being the “featherie.” This primitive ball was crafted from a leather pouch filled with goose feathers and stitched together. However, featheries were expensive, time-consuming to make, and not very durable.

In the mid-19th century, the “gutty” golf ball was introduced, made from solid gutta-percha (a rubber-like substance derived from the sap of the gutta tree). Gutty golf balls were cheaper, more resilient, and easier to produce, which helped popularize the sport of golf.

The 20th century brought the advent of the rubber-core golf ball, which ultimately paved the way for the modern golf balls we see today. These contemporary designs are categorized by construction and range from one-piece golf balls to six-piece wonders.

One-Piece Golf Balls

One-piece golf balls are the simplest and most affordable type, typically used for practice or at driving ranges. They are made from a single solid piece of Surlyn or similar material, an ionomer resin known for its durability and cut resistance.

While they offer limited performance, one piece balls are excellent for beginners and recreational play.

These balls consist of:

  1. Core: A solid or liquid-filled core typically made from rubber or rubber-like materials. The core controls the ball’s overall compression, spin, and distance capabilities.
  2. First intermediate layer: This layer is usually made from a firm rubber material designed to enhance energy transfer and optimize distance on long shots.
  3. Second intermediate layer: A softer rubber or ionomer material is used for this layer, which helps increase spin control on mid-iron and short-game shots, giving players more control over the ball’s trajectory.
  4. Third intermediate layer: This layer is made from a softer material than the second intermediate layer, improving spin control and providing better greenside performance.
  5. Cover: The outermost layer, made from urethane, offers a soft and responsive feel, providing increased spin control and precision on short game shots.

Five piece balls are favored by elite players seeking the best possible performance from their equipment. They have become the most popular option on the LIV or PGA tour, even more popular than a four piece ball. The three thin layers in the middle help golfers add spin and control to their shots.

The number one five piece ball is the TaylorMade TP5.

Six-Piece Golf Balls

Six-piece golf balls are the most advanced and complex designs available. Currently, they are rare and are typically only used by the most discerning golfers.

Six piece balls feature a solid or liquid-filled core, four intermediate layers of varying materials, and a urethane cover. This intricate construction allows for greater control, feel, and distance optimization.

The six layers in these golf balls are:

  1. Core: A solid or liquid-filled core made from rubber or rubber-like materials, which determines the ball’s compression, spin, and distance capabilities.
  2. First intermediate layer: Composed of a firm rubber material, this layer maximizes energy transfer and provides increased distance on long shots.
  3. Second intermediate layer: Made from a slightly softer rubber or ionomer material, this layer enhances spin control on mid-iron shots and short game shots, allowing players to control the ball’s trajectory better.
  4. Third intermediate layer: This layer features an even softer material than the second intermediate layer, further fine-tuning spin control for improved greenside performance.
  5. Fourth intermediate layer: The outermost intermediate layer, made from a material that balances softness and firmness, serves to optimize the ball’s overall performance by combining the benefits of the inner layers with the cover’s characteristics.
  6. Cover: A urethane cover that offers a soft and responsive feel, enabling increased spin control and precision on short game shots.

Six-piece balls are still largely in development and unavailable to buy widely. Most golfers are unable to discern the difference between five and six layers, so the extra cost is not worth it.

How Golf Balls are Constructed

The construction of a golf ball varies depending on its design and intended use. Generally, the process involves the following steps:

  1. Core production: The core is manufactured using a rubber or rubber-like material, either as a solid piece or with a liquid center.
  2. Layer application: Depending on the ball’s design, additional layers are applied to the core using various materials and manufacturing techniques.
  3. Cover molding: The outer cover, either Surlyn or urethane, is molded around the core and intermediate layers using a process called injection molding or compression molding.
  4. Dimple formation: Dimples are created in the cover during the molding process using specialized molds with dimple patterns.
  5. Quality control: Each ball undergoes rigorous testing to ensure it meets specific size, weight, and performance standards.
  6. Finishing touches: Golf balls are polished, painted, and branded with logos and identification markings.

Most golf balls follow a very similar manufacturing process.

Ball Size

According to USGA regulations, a regulation golf ball’s diameter cannot be less than 1.68 inches. Balls don’t have a maximum size, but a bigger golf ball will be less aerodynamic and will be harder to get into the hole on the greens.
