What is Sandblasting?
Sandblasting is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface, or remove surface contaminants. Sandblasting is just one of several blasting-type surface finishing processes. There’s also shot blasting, which is even more effective at smoothing otherwise rough and rigid surfaces.

What is Shot Blasting?
Shot blasting: abrasive gets acceleration through the throwing wheel, which is rapidly turning in a special steel housing, with one side oriented opening. Shot blasting directly converts electric motor energy into kinetic abrasive energy by rotating a turbine wheel. The capacity of each wheel goes from approximately 60 kg per minute up to 1200kg/min. With these large amounts of accelerated abrasive, wheelblast machines are used where big parts or large areas of parts have to be derusted, descaled, deburred, desanded or cleaned in some form.

What is Shot Peening?
Shot peening is a cold work, surface modification process aimed to improve the fatigue life of metal components through inducing compressive residual stresses. It is used when components experience metal failure due to high-cycle operating conditions. Shot peening is commonly seen in the aerospace, automotive, heavy machinery, and power generation industries.
