Our Superior Shot Blasting Services
Shot blasting removes rust, dirt, and solidified contaminants from the surface of metal parts. Halo metal prep accepts parts of all sizes for the shot blasting process, with equipment on site of varying sizes to accommodate both large and small pieces.
The media is loaded into the machine, and either a central centrifugal wheel flings or an Air Propelled Blast Nozzle accelerates the media at the workpiece, knocking off debris from the surface. Media can reach speeds of 200-800 feet per second during the process.
Shot blasting can be used to finish metal surfaces, but it can also be used to prepare them for painting or coating. Shot blasting with spherical media can actually reinforce the workpiece by impinging and creating residual stress. Without this process, micro-cracks that are present could worsen and lead to splitting or cracking. This shot blasting/peening process can be used as a process specification when you set parameters and perform it within those parameters i.e. how hard you hit the part, how much time processed, etc. When you perform shot blasting with spherical media under specified parameters, it is called shot peening.
Several materials can be shot blasted, including:
- Carbon steel
- Engineering steel
- Stainless steel
The process of shot blasting (Colloquially known as Sandblasting)—used to involve silica sand, but any material containing more than 1 percent silica is now banned internationally due to the particulates that are created, which when inhaled can lead to silicosis.
At Halo, we take quality control very seriously indeed. Each batch of parts we finish is inspected closely for a perfect finish. Many times, the shot blasted finish is the final stage of part preparation, so it is imperative that each part is finished to the required standard.
