Shot Blasting Technology,
Built as One System
High-performance surface cleaning and preparation through high-velocity abrasive blasting. Axmann designs, builds, installs, and commissions the entire line, from blast wheels to dust collection and media recirculation.
The Industry Standard for Mechanical Surface Cleaning
Shot blasting is a mechanical surface treatment process that propels high-velocity abrasive media, steel shot, steel grit, or cut wire, against a component at speeds of 60–80 m/s. The impact strips scale, sand residue, rust, oxide layers, and other contaminants from the surface, leaving a clean, profiled finish ready for coating, painting, or further processing.
Unlike chemical pickling or manual grinding, shot blasting is fully dry, produces no hazardous waste streams, and delivers a consistent, measurable surface quality, typically Sa 2½ or Sa 3 to ISO 8501-1. In foundry environments, it is the essential final step between shakeout and dispatch: every casting that leaves a modern foundry has been shot blasted. Axmann integrates shot blasting directly into the casting line, eliminating handling between processes and reducing floor space, labour, and lead time.
The 6-Step Shot Blasting Process
A continuous, automated flow from raw casting to surface-ready component, every stage engineered by Axmann.
Loading & Fixturing
Parts are loaded onto the machine carrier, drum, hanger, roller conveyor, or rotary table, and positioned for full, uniform surface exposure during blasting.
Blast Wheel Acceleration
High-speed centrifugal blast wheels, driven by electric motors, accelerate steel shot or grit to 60–80 m/s and project it in a precise, controlled stream at the component surface.
Media Impact & Cleaning
Abrasive particles strike the surface and mechanically remove scale, sand, rust, oxide, and burrs, creating a uniform anchor profile that maximises adhesion for subsequent coatings.
Dust & Debris Separation
A cyclone pre-separator and high-efficiency cartridge filter system capture dust, broken media, and fine debris, maintaining a clean blast environment and meeting air quality regulations.
Media Classification & Recirculation
Used media is conveyed back to a vibratory screen classifier that separates reusable shot from fines and oversized fragments. Good media re-enters the blast circuit; spent media is automatically replaced.
Unloading & Inspection
Cleaned components exit the machine and are verified against the specified surface cleanliness standard, Sa 2½ or Sa 3, before transfer to coating, painting, or dispatch.
What Axmann Provides
One supplier. One integrated system. One point of accountability, from process design through commissioning to decades of reliable operation.
Shot Blasting Technology in Detail
Advantages Over Manual & Chemical Cleaning
Consistent Sa 2½ / Sa 3 Cleanliness
Every part leaves the machine to the same measurable surface standard, no operator-to-operator variation, no missed areas.
Superior Coating Adhesion
The anchor profile created by blasting dramatically increases the bond strength of paint, powder coat, or protective coatings, extending service life.
Extended Component Life
Compressive residual stress induced by shot peening improves fatigue resistance, critical for dynamically loaded castings and structural parts.
No Chemicals, No Hazardous Waste
A fully dry mechanical process, no acids, no solvents, no VOCs. Eliminates chemical procurement, handling, and disposal costs entirely.
High Throughput, Low Labour
Automated blasting cycles process hundreds of parts per hour with minimal operator input, freeing your workforce for higher-value tasks.
Closed Media Loop
Media recirculation and automatic classification keep abrasive consumption to a minimum, lowering operating cost and reducing waste.
