Ultrasonic Cleaning for Automotive

Every rebuild lives or dies on cleanliness: carbon out of ring grooves, varnish out of galleries, brake dust off hydraulics — without abrading a single machined surface or leaving media where it can circulate.

Misonics systems serve engine reconditioners, transmission shops, motorsport teams and fleet workshops — from bench units for carburettors to platforms that take a block and crank.

The Contamination Problem

What we remove in automotive

Carbon & combustion deposits

In ring grooves, ports, valves and piston crowns — the rebuild-critical soil.

Varnish & oxidised oil films

Through galleries, valve bodies and hydraulic components.

Brake dust & wear metals

Embedded in calipers, ABS components and hydraulic hardware.

Gasket residue & sealants

On mating faces where scraping damages the surface.

Machining swarf & lapping paste

In new-machined components ahead of assembly.

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

Decoked inlets, before and after

Diesel inlet manifolds and throttle bodies from real service, photographed as received and after the immersion cycle. Drag the handle across to compare.

Throttle body bore. Coke bridging the bore and sitting on the butterfly seat. No bead blast, no scraping — the casting comes out with its machined finish intact.

Manifold flange port. The port that was closing up on itself. Airflow is the whole job of this casting, and it is measurable before and after.

A pair of manifolds, as received. Both banks together, exactly as they arrived on the bench. Cleaned as a set, so the engine gets a matched pair back.

Components We Clean

Real parts, real materials

Engine reconditioning

Blocks, heads, cranks, pistons, rods — carbon and varnish out of galleries and grooves without media damage.

BlocksHeadsPistonsCranks

Fuel & induction

Carburettors, injectors, throttle bodies, intake components — restored flow without disassembling every passage.

CarburettorsInjectorsManifolds

Driveline & brakes

Transmission valve bodies, ABS components, calipers and hydraulic hardware — clean to inspect and rebuild.

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.

Powersonic

Bench units for carburettor and small-component work.

Chemistry

Matched to the soil and the substrate

Aluminium-safe inhibited alkaline chemistry is the workhorse — aggressive on carbon, safe on castings and plated surfaces, with oil separation keeping the bath alive through workshop volume.

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 automotive engineers ask us

Will it strip carbon from ring grooves?
Yes — without touching groove dimensions, which is the whole argument against scraping and blasting.
Is it safe on zinc carburettor castings?
With inhibited chemistry, yes — standard work, proven on your parts in the trial.
Can a small shop justify one?
Bench units start at 3.3 litres — carburettor and injector service pays for one quickly.
What about magnesium motorsport parts?
Magnesium demands specific chemistry — confirmed by trial before any production cleaning.
