Blasting
We can also blast the surfaces of components in accordance with the relevant standards (ISO 8501-1,2 and 3; ISO 8503-1,2,3 and 4; ISO 8504-2 and 4) and with the standards relating to the preparation of surfaces for thermal spray applications.
Surface preparation degrees:
|
Sa 1 |
Light blasting |
On the view without magnification On the view without magnification tool the surface must be free from traces of oil, grease and dirt, and from poorly adhering mill scale, rust, paint and debris |
Low cost |
|
Sa 2 |
Thorough blasting |
On the view without magnification tool the surface must be free from traces of oil, grease and dirt, and from poorly adhering mill scale, rust, paint and debris Any remaining contaminants must stick firmly. |
|
|
Sa 2 ½ |
Very thorough blasting |
On the view without magnification tool the surface must be free from traces of oil, grease and dirt, and from poorly adhering mill scale, rust, paint and debris Any remaining traces of contamination need to look only as slight staining in the form of spots or stripes. |

Sa 3 |
Blast cleaning to visually clean steel |
On the view without magnification tool the surface must be free from traces of oil, grease and dirt, and from poorly adhering mill scale, rust, paint and debris It should have a uniform metallic color |
For paint applications Economically demanding |

Blast cleaning for thermal spray applications (S.A.M.) |
On the view without magnification tool the surface must be free from traces of oil, grease and dirt, and from poorly adhering mill scale, rust, paint and debris It should have a uniform metallic color, should be free of oxide Also must meet the surface preparation requirements for thermal spray applications, in accordance with the relevant standards |
For thermal spray applications Economically most demanding |
Material for blasting:
Artificial corundum (brown)
Al2O3 95,0 % min
Fe2O3 0,3 % max
TiO2 3,0 % max
SiO2 1,0 % max
The grain size is selected according to the:
- surface type and hardness
- technical requirements for the selected thermal spray method
- requested surface roughness of the component.
We blast in:
- Manual blasting cabin
- Semi-automatic blast cabin with charging carriage
- Blasting box
- mobile blasting device with exhaustion
