Injection Mould and Die Cleaning, Ultrasonic

A mould is a precision tool that spends its life being coated in the thing it must not keep: release agents, outgassing residues, carbonised films. Every manual clean risks the cavity surface; every abrasive clean guarantees it wears.

Misonics systems clean dies, moulds and tooling without touching dimensions — and castings without embedding media — proven on your tooling before you commit.

The Contamination Problem

What we remove in molds, castings & foundry

Release agents & waxes

Layered onto cavity surfaces, progressively degrading finish quality.

Outgassing & resin residues

Bonded films from plastics and rubber processing, in vents and texture.

Carbonised films

Baked residues on hot-work tooling and die casting dies.

Casting sand & investment

Residues in cored passages after shakeout.

Oxides & scale

Al₂O₃ and heat scale on dies and castings.

Neck-ring die segment before and after ultrasonic cleaning — The same die segment — serial 30163 stamped on both shots — as it arrived, and after ultrasonic cleaning. Carbon and baked residue gone from the clamp face and cavity, with no abrasion and no dimensional change. *— click to enlarge*

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

Trial Evidence

Mould tooling, before and after

Blow-mould and injection tooling photographed as it arrived and after a documented cycle. Drag the handle across to compare.

Blow mould base cone. Release agent and polymer burn on the forming face. The vents and the machined finish are the asset — nothing here was polished out.

Bottle cavity. Stained cavity to a readable surface. A blasted mould is a shorter-lived mould; this is the alternative.

Ejector pins in the die plate. Carbonised pins standing in their bores. Pins clean in place, so the plate does not have to be stripped to get them back.

Components We Clean

Real parts, real materials

Injection & blow moulds

Cavity sets, cores, vents and inserts — residue out of texture and vent slots without polishing dimensions away.

CavitiesVentsInserts

Die casting & hot work

Dies and tooling — carbonised films off without weld-repair-inducing surface damage.

DiesCoresSprue bushes

Castings

Aluminium and iron castings — sand out of cored passages, oxide off surfaces, no embedded media.

Glass bottle blow-mould halves, cleaned — A glassware blow-mould opened for service — polished cavity halves like these come through ultrasonic cleaning with carbon and release residue gone and not a mark on the mould face. *— click to enlarge*

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 G4 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

Mould chemistry must strip resin and release films while protecting polished cavity steel and aluminium — inhibited, temperature-controlled, and proven on a sacrificial insert first.

FAQ

What molds engineers ask us

Will it dull a polished cavity?

No — cavitation removes deposit, not steel. That is the argument against every abrasive alternative.

Can vents and texture be cleaned without opening them up?

Yes — cavitation works inside vent slots and texture where hand cleaning cannot go and peening should not.

How fast between production runs?

Mould-set cycles run inside a changeover window; the trial gives the real number.

Is chrome-plated tooling safe?

With correctly selected chemistry, yes — confirmed on your tooling first.
