The paint flows from the center outlet port and moves across the surface of the bell cup. The paint completely covers the bell cup surface and then, right at the very edge, liquid strings are formed. The liquid strings snap and form the droplets. This is the atomization process.

What are the 3 stages of atomization?

A three stage atomizer has been constructed consisting of airblast, swirl and effervescent stages allowing for more than one mode to contribute to the primary and secondary atomization of a single liquid jet.

What is atomization in spray painting?

Spray atomization is the transformation of a liquid into a spray of fine particles in a vacuum or a surrounding gas. The breakdown of the liquid into small particles is achieved when compressed air mixes with the liquid.
