Low-Volume High-Pressure (Conventional) Spray (LVHP)

LVHP spray guns operate with compressed air from an air compressor to atomize the paint. Pressures typically range from 40 to 70 pounds per square inch (psi).

High-Volume Low-Pressure (HVLP)

HVLP spray guns operate with a high volume of air delivered at 10 psi or less to atomize the paint.

Airless Spray

In an airless spray gun, the paint is atomized by increasing the paint's fluid pressure (ranges from 500 to 6,500 psi) without introducing a pressurized air flow.

Air-Assisted Airlesss

About 150 to 800 psi of fluid pressure and 5 to 30 psi of air pressure are used in an airassisted airless gun to atomize the paint.

Electrostatic Spray

With an electrostatic spray gun, the atomized paint droplets are charged at the tip of the gun by a charged electrode. The part to be painted is electrically neutral, and the charged paint droplets are attracted to the part.

Rotary Atomizers

Instead of air or fluid pressure, rotary atomizers use centrifugal force to atomize the paint and electrostatic charging to attract the paint to the part.

Roll Coating

With roll coating, the paint is applied by one or more auxiliary rolls onto an application roll, which then rolls across the conveyed flat part.

Dip Coating

Parts are painted by dipping them (usually by conveyor) into a tank of the paint.

Flow Coating

In a flow coat system, 10 to 80 separate streams of paint are directed to coat all surfaces of the parts as they are carried through the flow coater on a conveyor.

Curtain Coating

In curtain coating, a waterfall flow of paint coats a part conveyed horizontally. The paint flows at a controlled rate from a reservoir through a wide variable slot.

Autodeposition

Autodeposition is an oxidation-reduction precipitation process used to deposit organic paint films onto iron, steel, zinc, and zinc alloy-plated substrates.

Electrocoating

In electrocoating, a paint film from a waterborne organic solution is electrically deposed onto a part.
