What is Sand & Shot Blasting?
Sand & Shot Blasting are industrial surface preparation methods used to clean, smooth, or roughen material surfaces. These processes use high-pressure streams of abrasive materials to remove rust, paint, scale, and contaminants.
In sand blasting, fine sand or abrasive particles are propelled at high speed to clean the surface. In shot blasting, small metal shots or steel particles are used to impact the surface and remove impurities.
Industries widely use these techniques for metal surface preparation, rust removal, and surface finishing before painting or coating.
Sand Blasting Process
The sand blasting process uses compressed air to blast abrasive particles against the surface of a material. This process removes unwanted layers such as rust, paint, grease, and dirt.
Steps in the sand blasting process include:
1. Surface Inspection
Technicians inspect the surface to determine the level of cleaning required.
2. Equipment Setup
Operators prepare the blasting machine and select the appropriate abrasive material.
3. Blasting Operation
High-pressure air propels abrasive particles onto the surface.
4. Surface Cleaning
The abrasive impact removes contaminants and creates a clean surface.
5. Final Inspection
Technicians check the surface quality before further processing or coating.
This method is highly effective for cleaning large metal surfaces.
Shot Blasting Process
The shot blasting process uses steel shots or metal beads instead of sand. These particles strike the surface at high speed to remove rust, scale, and contaminants.
Steps in the shot blasting process include:
-
Surface preparation and cleaning
-
Loading the component into the blasting machine
-
Propelling steel shots onto the surface
-
Removing rust and impurities
-
Inspecting the finished surface
Shot blasting is widely used in industrial manufacturing and metal finishing.
