Abstract:  
AUTOMATED BLASTING, peening, and finishing are the solutions of choice for companies seeking consistent results when processing high volumes of parts with specific finishing specifications. Repeatability is the value proposition that makes these operations successful, and a critical component to achieving repeatability is choosing and properly utilizing the right nozzle for the job. Repeatability in high-volume parts peening, finishing, or blasting operations is achieved by delivering a uniform quantity of media at a consistent velocity and striking the target surface area in the same way each and every time. The internal shape of the nozzle guides and distributes the media as needed for the application. Different nozzles with different shapes offer different advantages depending on the application. Pressure blasting is chosen for some high-production air-powered processes because it propels media at a higher velocity through the blast nozzle than suction blasting. In air-powered pressure blasting, media feeds from a pressure vessel into a moving stream of compressed air through a metering valve, blast hose, and nozzle.
