What is an Internal and External Shot Blasting Machine?

An internal and external shot blasting machine is specially designed to blast both the inner surfaces (internal areas) as well as outer surfaces (external areas) of a component using high-velocity abrasive media.

These machines are widely used for:

  • Rust removal

  • Scale removal

  • Heat treatment cleaning

  • Surface polishing

  • Paint and coating preparation

  • Improving fatigue strength

Internal areas are usually difficult to reach manually—hence internal shot blasting machines are engineered with precision nozzles and automated systems to reach deep cavities, bores, tubes, and internal channels.

External surfaces require uniform blasting to remove scale and achieve smoothness on the outer layer of components.

Importance of Internal & External Shot Blasting in Industry

Surface finishing is not just about appearance—it directly affects the life of the component, its mechanical strength, corrosion resistance, and overall performance.

Internal and external blasting helps in improving:

  • Fatigue strength

  • Bonding with industrial coatings

  • Wear and tear resistance

  • Dimensional quality

  • Surface roughness parameters

  • Component durability

This is why industries like automotive, foundries, steel plants, aerospace, oil & gas, and heavy engineering depend on shot blasting in every production stage.
