Cemented carbide nozzles are manufactured from hot pressing with straight bore and venturi bore type. Due to its hardness, low density and excellent wear and anti-corrosion, cemented carbide nozzle has been widely used in sandblasting and shot peening equipment, offering a long life with optimum air and abrasive use.
Cemented carbide nozzles are made of high grade tungsten carbide. The hardness reached over HRA90 degree while the anti-bending degree reached over 2300N/mm. On machining cemented carbide nozzle, the precision grinding and surface treatment can be reach to Ra0.1 of the bore roughness and the Ra0.025 of the R place of both ends. There is a scientific curvature radius design in the both entrance which can ensure a smooth transit of the thread. Due to the overall materials processing, and no elevation in the bore, the phenomenon of easy-bending and plugging of cemented carbide nozzle has been improved comparing with the ruby nozzle.
