Shot
Blasting

Shot blasting propels round abrasive media, known as shot, against a surface to strip away contaminants and, where required, improve the surface finish. Choosing the right shot media is a key part of the process. The size and hardness of the shot determine how much material is removed from the surface, and the material being cleaned also affects how well the process works. For this reason, the type and size of shot are normally selected to suit the composition of the part being blasted.

​

The method of propulsion, and the speed it gives the shot, is equally important. The most common approach uses a centrifugal wheel. The shot is fed into the wheel, accelerated to the required velocity and then thrown out towards the surface being treated. An operator or machine directs the stream of media across the part to clean it.

Materials that can be shot blasted include:

​

• Carbon steel

• Engineering steel

• Stainless steel

• Cast iron

• Titanium

• Copper

• Concrete

• Certain types of ceramics
