Ultrasonic Cleaning for Spray, Coating & Atomisation

A worn or blocked nozzle sprays money onto the floor: wrong flow, wrong pattern, wrong coating thickness. Drilling out a blocked orifice destroys it — cavitation clears it without touching the geometry.

Misonics systems restore nozzles, guns and atomisation hardware to specification flow, verified by test, in cycles measured in minutes.

The Contamination Problem

What we remove in spray, coating & atomisation

Dried coatings & paints

Cured films in orifices, passages and needle seats.

Adhesives & laminate carryover

Bonded residues through applicator hardware.

Polymer & resin build-up

In atomisation air caps and fluid passages.

Product residues

Food, chemical and agricultural formulations dried into spray hardware.

PTFE & release coatings overspray

Accumulated films on fixtures and hardware.

Powder coating line — panels on an overhead conveyor entering the curing oven
A powder line lives or dies on its hardware — guns, nozzles, hooks and hangers all build coating with every pass, and every gram of it ends up in the finish or the reject bin. Ultrasonic stripping brings them back to bare metal without abrasion. — click to enlarge
The endpoint is a defined, repeatable process condition — cycle time, chemistry, concentration, frequency and temperature are recorded parameters, not operator judgement.
Components We Clean

Spray guns & applicators

Fluid passages, needles, seats and air caps — restored without re-machining seats.

GunsNeedlesAir caps

Precision nozzles

Atomisation, coating and dosing nozzles — orifice geometry preserved, flow restored to spec.

OrificesSwirl insertsTips

System hardware

Manifolds, valves, filters and fittings through coating and dosing systems.

Why Ultrasonics — And Why These Machines

Cavitation cleans geometry it cannot see

Bubble collapse at the liquid–metal boundary lifts contamination from passages, galleries and cavities without anything touching the surface. Nothing abrades, nothing embeds, no metal is removed.

GeneratorResonance held all shift

The VarioSonic G5 tracks the transducer array as temperature and load shift — conversion efficiency up to 95%.

Sound fieldSweep modulation

Eliminates standing-wave hot and cold zones across a loaded basket.

Process controlLogged, recipe-driven cycles

Stored recipes and logged cycles — audit evidence produced as a by-product of running.

Bath conditionFiltration & oil separation

Multi-stage filtration and weir oil capture hold results steady as the bath loads.

SupportOver-the-air diagnostics

Most faults identified — many resolved — without a site visit.

ConstructionBuilt to work hard

Heavy 316 stainless tanks, tested before despatch, every wearing part replaceable.

Equipment Fit

The machine follows the process

From manually loaded single-tank units to automated lines — and engineered systems where the catalogue ends.

Chemistry

Matched to the soil and the substrate

Chemistry follows the coating — alkaline for most paints and product residues, specialised formulations for cured and crosslinked films — proven per coating system in trial.

Prove it on your parts

Where an application needs validation, we clean sample components in our laboratory, document the result, and specify the machine around the verified process. If ultrasonics is the wrong answer, the trial shows that too, and we will tell you.

FAQ

What spray engineers ask us

Can ceramic nozzles be cleaned?
Yes with thermal-shock care — parameters keep temperature transitions gentle.
Is flow actually restored?
Flow-test before and after is the honest measure; the trial produces those numbers.
Cured two-pack coatings too?
Harder, sometimes staged — the trial establishes what is recoverable and what is scrap.
How fast per gun set?
Minutes — a booth's guns turn around inside a break.
