Wet blasting

At Schavicast, we understand the importance of finishing surfaces in an effective and high-quality manner. That is why we offer wet blasting methods that ensure satin smooth results. Wet blasting has numerous advantages over dry blasting.

A distinctive feature of wet blasting is the smooth finish achieved by using running water. This ensures that the medium does not penetrate the part, while there is also no dust formation as in dry blasting, where the abrasive is crushed by the powerful impact.

At Schavicast, we use a specially designed, seal-less and highly wear-resistant polyurethane pump to mix water and abrasive and pump this mixture to the blast gun. This mixture is also used to keep the abrasive mix in the tank homogeneous via a bypass system.

In the blasting gun, compressed air is mixed with the water-blasting agent mixture to increase the ejection force, resulting in the specific wet-blasting effect. The water dampens the abrasive action of the abrasive, achieving an optimal finish.

The mixture of water and abrasive is in a reservoir at the bottom of the blast cabinet and is pumped through hoses to the nozzle using our specially designed gasket-free polyurethane pump. At the nozzle, compressed air is added to the mixture, providing acceleration and a cleaning effect. After impacting the workpiece, the mixture flows back to the pump reservoir for reuse. Finely crushed blast media and other contaminants are discharged to a drain or an optional settling tank with filter, located behind the blast cabinet.
