General Introduction to Shot Blasting
Shot Blasting is a surface treatment process using high velocity steel abrasive. Shot blasting is
method through which it is possible to obtain excellent cleaning and surface preparation for
secondary finishing operations.
Shot blasting is commonly used for:
•
The cleaning of iron, steel, non-cast parts, forgings, etc.
•
Mechanical cleaning of sheets, rods, coils, wire, etc.
•
Shot peening to alter mechanical properties (increasing resistance to fatigue for
springs, gears, etc.)
•
Preparing surfaces to be painted, coated, etc.
In general shot blasting concentrates abrasive particles at high speed (65-110 m/second) in a
controlled manner at the material thereby removing surface contaminates due to the abrasive
impact.
Initially in the 1930’s the shotblasting process used compressed air for propelling the steel
shot. This method remains in use today for cleaning metal frames and weldments.
