Sandblasting vs. Abrasive Blasting: What’s the Difference?

March 26, 2020

Manufacturers that need metal parts also need the surfaces of those parts to look a certain way and to be perfectly clean before use. In the finishing business, there are two common ways to finish, alter and clean metal surfaces before use: sandblasting and abrasive blasting.

What is the difference between sandblasting and abrasive blasting? While both are commonly used, they are distinct and different processes that work best in different circumstances. To help you better understand your options and make the best decision for your project, here’s a look at sandblasting vs. abrasive.

What Is Sandblasting?

With sandblasting, fine bits of material are propelled at extreme velocities so that a metal surface may be cleaned or etched. While sandblasting is the most common term to describe this process, materials other than sand can be used to do the cleaning and/or etching. In fact, because of health issues that sandblasting and the inhalation of sand dust can cause, many finishing operations now use alternate materials for their blasting — such as walnut shells, powder abrasives, steel grit, copper slag and others.

The sandblasting process is always carefully monitored, and those doing the sandblasting wear protective gear to prevent inhalation. When done properly, sandblasting is one of the most effective ways to clean and etch metal surfaces.

What Is Abrasive Blasting?

Abrasive blasting goes by many different names, including abrasive jet machining, pencil blasting, abrasive micro-blasting, micro-abrasive blasting and more. No matter the name, the process includes using gas to propel abrasive materials at high velocity to wear away the surfaces of particularly brittle, heat-sensitive, hard or thin materials. We most often see abrasive blasting used to form edges or to create shapes that are more intricate.sandblaster air

Which Approach Is Best?

Which approach is best for your next project: sandblasting or abrasive blasting? The answer really depends on the project at hand and its unique requirements. For example, parts and surfaces that simply need cleaning or basic etching might do best with sandblasting. But, as noted above, specific types of material and the formation of more intricate shapes might require abrasive blasting.
