Wet blasting The liquid honing or wet blasting process uses water to cushion the blast media and eliminates damage to the surface of the component, mold or tool. This process is used for precision surface finishing and allows us to control and regulate the flow and type of material used in the blasting slurry. It also allows us to control the velocity, pressure, location (areas can be masked) and other engineered elements to provide the optimum finish for your part, mold, die or tool.
