Abrasive blasting is a vital part of the casting process. As the name suggests, it blasts the component with an abrasive material to smooth or roughen a surface, or remove contaminants.
Shot blasting uses metal shot – usually steel but also copper and aluminium – applied with a centrifugal force as the abrasive material. There are other forms of blasting, such as sandblasting, which traditionally used silica sand shot at the component with compressed air.
Standalone shot blasting and sandblasting services
Sandblasting is much less common today due to the hazards involved with using sand – shot blasting is both safer and more environmentally friendly – but is often used as a catch-all term for abrasive blasting as it’s been in use for well over a hundred years.
