A nozzle is a device designed to regulate the flow of a fluid by converting pressure energy into kinetic energy. As the fluid passes through the nozzle, it accelerates—resulting in increased velocity—and depending on the nozzle’s shape, pressure can either increase or decrease.

Nozzles come in various geometries—convergent, divergent, or convergent-divergent—depending on their intended application.

They are used across a wide range of industries:

Industrial – for spraying paints, lubricants, or water

Aerospace – in rocket and jet engines

Fluid mechanics – to control compressed gases or steam

Agriculture – in sprinkler and irrigation systems

Manufacturing – as injectors in plastic or ceramic forming processes

In ceramic production, nozzles play a key role in several stages, especially during shaping, glazing, and decorating.

Given the abrasive nature of ceramic slips, glazes, and oxides, it is essential that nozzles be made from materials resistant to wear and corrosion. Optimizing nozzle design and material selection is crucial to ensure high-quality output, process efficiency, and long service life in ceramic manufacturing.
