What is shot blasting used for?

Shot blasting is used most commonly to clean the surface of metals. Depending on the equipment used, this process is also used for altering the textures or surface coating of the metal for decorative purposes to enhance its appearance.

Shot blasting techniques:

There are various shot blasting techniques used for numerous industrial purposes:

• Abrasive blasting

This technique of metals involves spraying of abrasive supplies like water, sand, high pressured air or fine glass particles at extremely high speeds on the metal to be cleaned or polished. Abrasive blasting requires potent and high-powered equipment and is often referred to as pressure washing or sand blasting. For eco-friendly other organic and environment friendly supplies may be used as a blasting medium such as basking soda. Selecting the kind of material to be used as a medium depends on the type of application.

Abrasive blasting equipment can vary from a small back pack sized shot blaster to industrial sized which can be the size of a trailer.

The cabinet of the machine is then connected to a hose with a nozzle on its mouth by which blasting experts are in a position to direct the medium on the metallic surface.

• Grit blasting

This is an additional type of exactly where the medium used for blasting is gritty sand particles. Grit blasting is commonly used for smoothing rough metallic surfaces or adding a rough texture to smooth metallic surfaces. There are transportable as nicely as stationery pieces of equipment that might be used for depending on the required pressure streams. Small grains of sand are pressure-propelled from an air gun onto the metal. Grit blasting is commonly used to attain a frosted effect on metals or to clean off paint from metallic surfaces.

An additional off-shoot of is bead blasting where small particles of glass are used for blasting rather than sand. This is used to clean swimming pool floors off stains and fungus as nicely as on automobiles to clean paint.
