What is the difference between shot peening and shot blasting

Shot blasting uses abrasives to clean or smooth the surface to prepare it for processing; shot peening uses the plasticity of metal to prolong the life of the part. In shot peening, each shot acts as a ball-peen hammer. The process makes the surface of the metal part stronger and more resistant to cracks, fatigue, and corrosion. Manufacturers can also use shot peening to give the piece a textured surface.

Like with shot blasting, the choice of shot depends on the application. Shot peening usually involves steel, ceramic, or glass shots. The material is reusable, making it an efficient and cost-effective process for strengthening metal parts. Shot blasting and shot peening are both critical steps in the metal manufacturing process.

Its media must be in the exact and same diameter, to avoid unnecessary damage to the material upon impact. Shot Blasting is a process where prepare metal parts for additional process like painting or powder coating. Shot Blasting is essential step to ensure the coat sticks perfectly to the part.

This step also can clean off contaminants like dirt or oil, eradicate metal oxides such as mill scale or rust, or cleanse the surface to make it a new like. Simply put, people often use different shot terms interchangeably when they are referring to two completely different processes. This is the case with shot-blasting and shot-peening. Although both processes utilize shot technology, there is a significant difference between shot-blasting and shot-peening.

Like shot-blasting, shot-peening involves shooting abrasive materials at a metal surface through a centrifugal wheel. However, the goal here is not to clean the surface but to make it stronger. A blast machine needs media valves to regulate the flow of abrasive.

The inlet and outlet valves are vital components of the blast machine setup. They determine whether a pot is pressurized. Nozzles are needed to accelerate the abrasive out of the blast hose.

A blast machine also has various hoses: twin-line hoses, blast hose , and an inch hose. Last- but certainly not least- anyone who operates a blast machine needs to wear appropriate safety gear such as leather gloves, eye and hearing protection, abrasive-resistant clothing, and type-CE supplied-air respirator.
