Shot Blasting

In foundry, shot is used mainly to clean parts and dies. The sand used during the production process is compacted and strongly adhered to the piece and the dies, so blasting is used to detach it quickly and efficiently. It is an ideal cost-benefit system that achieves an unbeatable appearance and finish to the pieces.

Likewise, it is used for surface preparation, for which the shot is projected by means of a pressure jet on the pieces. Thanks to this blasting process, the piece is left free of any imperfection (such as rust, etc.), even giving a degree of roughness to the surface if necessary, leaving the material thus prepared for subsequent treatments.

Shot Peening is a process conceived to increase the resistance to fatigue of the material, which consequently allows to increase the life cycle of the parts, as well as their load capacity.

This treatment consists of exposing the metal surface to a high speed shot blast, which allows converting the residual tensile stresses generated by treatments such as milling, bending or heat treatment into compression stresses.

Finally, the shot has been used to cut the granite blocks that are extracted from the quarries.
