What is shot blast finish?

Shot blasting is a specialized surface finishing process where small metal (or mineral) pellets, called blast media, are thrown onto the surface of a work piece at incredibly high speeds, ranging from 200-800 feet per second.

How does a concrete shot blaster work?

Shot blasting machines use a centrifugal blast wheel to shoot metal beads down at the concrete. While the wheel spins, the beads are funneled in, launching them out through a space aimed at the concrete surface. The high velocity of the metal beads chips away the top layer, exposing a cleaner surface.

Is shot blasting better than grinding?

Shot Blasting Works Faster on Most Surfaces Additionally, shot blasting is an aggressive method of cleaning and profiling, and it can help you reach your goals quickly and efficiently. Grinding is a more methodical way to remove coatings and create a smoother, more even surface.

What is the difference between sandblasting and shot blasting?

Essentially, the sandblasting process uses compressed air to shoot some form of abrasive media like sand against the product being treated. Shotblasting employs centrifugal force from a mechanical device to propel treatment media upon the product.

Why we use shot blasting?

Shotblasting is a method used to clean, strengthen (peen) or polish metal. Shot blasting is used in almost every industry that uses metal, including aerospace, automotive, construction, foundry, shipbuilding, rail, and many others. There are two technologies used: wheelblasting or airblasting.
