Shot blasting is commonly used to achieve a smooth finish on a rough surface, as well as to remove any corrosion. This is done by firing pellets against the rough surface under high pressure, which removes the roughness, resulting in a smooth, even finish. Wheelblasting - a type of shot blasting - uses a wheel to drive the pellets against the surface, whereas airblasting uses compressed air.
Shot blasting is used across most industries, as it is an extremely popular way of shaping, cleaning and strengthening metal components. Sectors that utilise shot blasting include - but are not limited to - marine, aerospace, construction and automotive.
Whilst shot blasting is environmentally-friendly since no chemicals are used, there is a risk of deformation to the parts owing to the aggressive nature of the process.
