Precision Ceramic Nozzles
Ceramic nozzles are precision fluid and gas handling components designed to control flow rate, spray pattern, or gas distribution in demanding environments. Technical ceramics are considered when metal nozzles cannot meet requirements for chemical resistance, wear life, or high-temperature performance. Engineering factors include orifice diameter, bore geometry, outlet profile, concentricity, and internal surface condition. Korecera manufactures custom ceramic nozzles from customer drawings in Alumina, Zirconia, and Silicon Nitride.
Nozzle Types & Functions
