Steel foundries (similarly to cast iron foundries) need shot blasting of melted (sand or soil) objects. Casting residues are eliminated to obtain products ready for further processing. The handling of work pieces through the shot blasting machine can take place by means of a motorised air conveyor with step-by-step feed (pneumatic doors) or continuous feed (rubber sealing curtains), a continuous belt conveyor equipped with rubber sealing curtains or feeding belts with intermittent loads. Processing with intermittent loads on a metal or rubber feeding belt facilitates the mixing of work pieces during shot blasting.
Cold-press forged products (similarly to cold-press forged products) must also be processed through shot blasting to eliminate impurities such as burrs, ridges and pigmentations. This procedure is carried out with intermittent loads through a metal or rubber feeding belt, or continuously using air or belt conveyors. It prepares the product for further processing.
Hot-press forged products often present burrs, ridges and pigmentation, which must necessarily be eliminated through shot blasting before further processing. Shot blasting is carried out with intermittent loads through a metal or rubber feeding belt, or continuously using air or belt conveyors.
