What is a Bowling Ball Made Out of | Easy Guide 2022

What is a Bowling Ball Made Out of? A bowling ball is a hard, large, heavy object used for bowling ball used in bowling. Bowlers use it to knock down pins with a series of throws.

A bowling ball is used to knock down pins while bowling. They come with a smooth outer shell and a solid core, usually hollow or filled with lead. 

The weight of a bowling ball varies by manufacturer, but the typical weight is between 330-360 lbs.

More so, if you’ve ever wondered what exactly bowling balls contain, it’s time to ask a pro. Here’s what you need to know. 

Bowling balls hold aluminum, a lightweight metal that provides good rebound when it comes into contact with the pins, and carbon fiber adds rigidity. 

If you’re a bowling enthusiast, you’ve probably seen or heard someone talk about the term “rebounding” when they talk about a bowling ball. It refers to how quickly the ball travels after striking the pins, depending on how tightly the ball hits them. It is determined mainly by the ball’s weight and spin rate. 

Material of Bowling Ball

It usually comes in a solid material, such as metal or wood. It contains a hole to place the pin in it. A bowler then rolls the ball down a lane of pins until it hits one of them, knocking it over—a strike scores when the ball knocks over three or more pins.

Here is the primary material of the bowling ball used in constructing the ball. 


Aluminum is the very essential stuff used in bowling balls today. It is robust, durable, and lightweight. Further, it also has good rebound and feels.


Epoxy is a rigid, clear plastic used to add weight to a bowling ball. It’s the best material for making a bowling ball because it provides a great combination of strength and weight.


A composite ball consists of a mixture of polyurethane, rubber, and resin. It gives the ball a softer feel than an aluminum ball.


A bowling ball can have different types of rubbers in it. However, most bowling balls consist of a combination of polyurethane and natural rubber.


The plastic uses to cover the outside of the bowling ball. In addition, it is a thin layer of plastic that applies over aluminum. It also protects aluminum from wear and tear. We can use plastic to improve the feel of the ball.

Manufacturing Process of Bowling Ball

There are many steps involved in manufacturing a bowling ball. It includes the raw material that goes into the ball, how it combines, and what kind of materials go into making the ball.

Step 1: The first step in manufacturing a bowling ball is obtaining the raw material. It may include different types of plastics, metals, and rubber.

Step 2: The raw material is then cut into the proper shape and size.

Step 3: Bowling balls consist of plastic and aluminum. We use plastic for the external shell and aluminum for the internal core. The two parts are joined together with a unique adhesive that keeps the parts separate until they are together.

Step 4: As well, the process starts with a mold. A mold is a container you’ll use to create a specific shape. The mold fills with plastic pellets that heat in a machine. 

Step 5: Moreover, by pouring the hot plastic into the mold, the plastic is allowed to cool. When it cools, you need to mold plastic so that the plastic can remove.

Step 6: Now, you’ll apply a thin coating of aluminum to the inside of the plastic ball. Aluminum is a light metal that is very compact and sturdy. It is also soft. 

Step 7: Aluminum is applied to the plastic ball by a machine that heats the aluminum and uses it inside the plastic ball.

Step 8: Besides this, the final step in the manufacturing process is to join the aluminum core to the plastic shell. Then, finally, you’ll complete it by melting the aluminum and plastic together with a machine. 

Step 9: You need to pour the molten plastic and aluminum into a mold. First, the molten plastic and aluminum are allowed to cool. Next, a plastic shell removes from the mold, and the aluminum core is lefts inside the plastic ball.

How to Choose the Bowling Ball

Step 1: The ball’s size: You need to determine the size by the size of the hole in the center. The larger the hole, the bigger the ball. In case, the hole is small then the ball will also be small.

There’s no rule for what size to make a bowling ball, but a larger one is easier to control, so more minor is usually better. 

A 10″ ball is ideal, and you can choose between a 10″ and a 12″ ball. A smaller ball rolls more efficiently on a carpeted surface and a giant ball on wood floors. Remember to put some wax on the floor before you start moving to reduce friction.

Further, you first need to decide how big the bowling ball should be. For instance, the ball is 1/2″ in diameter. You can know the size, you can also figure out what you need to cover it with. 

To calculate that, multiply the diameter by 4 (the radius), divide by 12 (the circumference), and then round up to the whole number.

Step 2: The shape of the ball: The shape of the bowling ball determines by the shape of the hole in the center. The larger the hole, the more round the ball. The smaller the hole, the more square or rectangular the ball is.

The shape of the ball affects the speed at which it rolls. Thus, the ball must contain material with optimal characteristics for rolling. 

In the bowling world, the ball is made of rubber because it rolls most predictably but is durable enough to last many games.

Step 3: The weight of the ball: The bowling ball’s weight is determined by how much material it contains. The heavier the ball, the harder it is to knock down pins.

Step 4: The type of surface: The bowling ball’s cover determines what kind of lane the ball rolls on. The rougher the surface, it’ll more hard to roll the ball.

The bowling ball should have a smooth, concave surface. It allows it to roll more efficiently, giving it better stability. On the other hand, a convex bowling ball would not be as stable and could move around more easily. 

You may also consider it in terms of the egg. An egg’s shape is pretty round. If you made an egg into a flat plane (with no depth), the yolk (or the “center of gravity”) would shift off to one side. It would also be more challenging to balance and decrease stability.

What are the Types of Bowling Ball

There are some kinds of balls that you should consider.


Dense balls are the most durable. They are usually made from aluminum and used for leagues with multiple lanes.
