Compressed air blasting

Blast cleaning of surfaces using various abrasives, with the abrasive being accelerated by means of compressed air when flowing through a nozzle.

Abrasives may be either conveyed out of pressure containers or drawn out of unpressurized containers. Today, the process is applied for surface finishing, for removal of ceramic mold residues in investment casting, and for cleaning of ingots in connection with a blasting chamber that can be remotely controled from outside the chamber.

The advantages of this process result from its flexibility with regard to selection of abrasives and from fast abrasive change. The rather simple system technology only causes relatively low investment costs.
