What is the difference between manual (hand blasting) and automated functions such as the rotoblast machines?
Manual blasting is utilized when the parts either require specific, directional blasting or are too big or fragile for tumbling. Rotoblasting provides an even blast surface over the entire exterior part. With hand blasting, we are able to perform custom exterior/interior blasting by controlling the location and concentration of blasting via time, direction and/or air pressure.
