The blast shots are mainly used for:
Descaling of bars in drawing mills, aluminum or bronze shotblasting, shotblasting of particular milling or die-pressed items, tile and cement block shotblasting, cleaning of surfaces in turbine shotblasting machines.
SPHERICAL BLAST SHOTS are obtained through fusion. They then undergo thermal treatments to confer optimal resilience and resistance to stress.
ANGULAR BLAST SHOTS are obtained through the crushing of spherical blast shots, they then undergo thermal treatments that confer a metallographic structure and maximum technicality.
