Shot Blasting Technology: Seminar Report (PDF)

Shot Blasting

Shot Blasting is a surface treatment process using high-velocity steel abrasive. Shot blasting is the process mainly used to make the surface smooth, rough, to remove surface contaminants, and for shaping a surface. It is also one of the easiest, quickest and convenient ways to remove impurities from the surface prior to any type of coating. It also implies problems like unequal finishing, more time and energy consuming and bad quality product. Shot blast production lines, both manual and automated systems, became possible with the introduction of centrifugal wheel blast machines. 

The system of shot blasting by the centrifugal wheel is more productive than by compressed air and achieves a better more uniform surface finish. 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 1930s, the shot blasting process used compressed air for propelling the steel shot. This method remains in use today for cleaning metal frames and weldments.

Use of Shot Blasting

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.

Shot Blasting Seminar Reports (PDF)

The seminar reports for mechanical engineering include the papers that discuss the process, basic components, and significance of the typical shot blasting machine. The papers for the shot blasting seminar report also describe the solution to the problem of the shot blasting process with the help of automation, which leads to time and energy consumed. In foundries, the handling of shot blasting machines having most hazards related to health, safety, and environment are involved. The seminar report also discusses the methods to reduce the risk level by implementing the assessment and improved control measures.  Download PDF papers for a seminar report on Shot Blasting.
