Ultrasonic Cleaning for Defence

Defence sustainment cleaning has two masters: the component, which is often fatigue-critical and coating-protected, and the framework, which requires every process to be repeatable, documented and auditable. Manual methods satisfy neither.

Misonics systems support ADF base workshops and defence contractors with logged, recipe-driven cleaning — from weapons components to vehicle and aviation hardware — with procurement compliance met through our partnered distributor network.

The Contamination Problem

What we remove in defence

Carbon & propellant residues

Fouling in weapons components and gas systems — bonded by heat and pressure.

Grease, CLP & preservative films

Through small arms, mounts and stored hardware.

Hydraulic varnish & fluid films

In vehicle and aviation actuation systems.

Salt & environmental contamination

On amphibious, marine and field-exposed equipment.

Machining and overhaul residues

Ahead of NDT, gauging and re-coating in depot maintenance.

The endpoint is a defined, repeatable process condition — cycle time, chemistry, concentration, frequency and temperature are recorded parameters, not operator judgement.
Components We Clean

Real parts, real materials

Weapons & armament

Small arms components, crew-served weapon parts, mounts and gas systems — carbon out of geometry brushes cannot reach.

BarrelsBoltsGas systemsSuppressors

Vehicle & land systems

Engine, driveline, hydraulic and brake components off protected and logistic vehicles.

HydraulicsDrivelineCooling

Aviation & maritime sustainment

Rotary and fixed-wing components and seawater-side maritime hardware under sustainment programs.

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.

MSX

Benchtop and workshop units for armoury and component work.

Chemistry

Matched to the soil and the substrate

Chemistry follows the substrate and the specification — including Brulin chemistries carrying US military and aerospace approvals where the maintenance system calls for them.

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 defence engineers ask us

Does cleaning affect phosphate or nitride finishes?
Correctly parameterised, no — finish compatibility is confirmed in the trial before the process is adopted.
Can armoury cleaning be standardised across sites?
Recipes are stored per component and cycles logged — the same program runs identically at every site.
Can you meet defence procurement requirements?
Compliance and accreditation requirements, including Avetta and ISO frameworks, are met through our partnered distributor network.
Is remote support available on base?
Subject to site connectivity policy — OTA support is standard on connected machines, and offline maintenance procedures exist where it is not permitted.
