Shot Blasting and Shot Peening
Shot blasting is a less refined technique, without the tight parameters of shot peening. Shot blasting is used for cleaning parts that were recently heat treated or manufactured and prepares them for the next stage in the manufacturing process.
Our shot peening and shot blasting processes utilize several types of media, such as ceramics, plastic beads, steel grit, aluminum oxide, and glass beads. In the shot blasting process we use steel grit, aluminum oxide, and glass beads specifically. Steel grit is an angular abrasive and can remove material quickly, as well as being able to rapidly etch a surface to provide a key for paint. Like steel grit, aluminum oxide is also an angular media. Aluminum oxide is used for scale and rust removal and as preparation for top coating, plating, and bonding where steel grit may be too harsh of a material. Glass beads are used for a superior finish that does not impregnate the surface with oxides that could lead to corrosion.
Our Industrial Metal Finishing Process
We specialize in all aspects of polishing, buffing, benchwork, and diamond finishing. High quality finishers can be hard to find, but at Halo Metal Prep we have the in-house expertise and skill to tackle the job quickly.
With metal polishing, we use abrasives that get progressively finer until we achieve a desired flatness, measured by a micrometer. When we undertake a polishing project, our aim is to provide a clean and defect-free finish. Buffing refers to the use of a buffing wheel to create a clean, attractive surface for finished parts.
For harder materials, we use diamond polishing. For example, tool steels, super alloys, and carbides all require working with diamond finishing to work the surface to the desired flatness and shine.
For complex parts, or smaller parts that cannot be finished using a buffing wheel, we complete jobs on the bench, manually.
