Parts and contaminants · 5 min readUltrasonic cleaning of orthopaedic implants in productionImplants carry coolant, polishing compound and particles on their way to packaging. The cleaning sequence, what ISO 19227 asks for, and the equipment.

Parts and contaminants · 4 min readUltrasonic cleaning of medical tubing, cannulas and channelsInside a narrow lumen nothing flows unless something pumps it. How to clean cannulas, tubes and drilled channels in production, and prove the inside is clean.

Parts and contaminants · 5 min readUltrasonic cleaning of electronic connectors for reliable contactOxide, flux, dust and old lubricant raise contact resistance. How to clean connectors, pins and charging ports without harming gold, silver or tin plating.

Parts and contaminants · 4 min readUltrasonic cleaning of communication equipment componentsRF housings, cavity filters, waveguides and antenna parts, often plated aluminium: gentle chemistry, no etching, no loose particles, and dry cavities.

Parts and contaminants · 4 min readCleaning sensors and microelectronic parts with ultrasoundSensor housings, probes, optical windows and sensor elements before assembly: what ultrasound cleans well, and which sensor types must never go into the bath.

Parts and contaminants · 4 min readCleaning precision electronics without damageWhich electronic components tolerate ultrasound and which do not, and how frequency, power, time, support and a sample test keep a cleaning process safe.

Parts and contaminants · 4 min readCleaning microsurgical instruments with ultrasoundMicrosurgical tips bend or break on contact. How fine instruments are held, cleaned and checked in hospitals, repair workshops and manufacturing.

Parts and contaminants · 4 min readCleaning medical device components before assemblyMachined, moulded and stamped parts bring oil, mould release and particles into a device. How to set up the cleaning step and validate it under ISO 13485.

Parts and contaminants · 4 min readCleaning dental instruments with ultrasoundBurs, files, forceps and hand instruments carry blood, calculus and cement. How the ultrasonic step fits dental reprocessing, and what stays out of the bath.

Parts and contaminants · 4 min readUltrasonic cleaning of precision parts before quality inspectionA coolant film or a single chip on a datum face is a measuring error, and a part that comes out of a warm bath is not yet the size on the drawing. How to clean precision parts so the inspection measures the part and not its dirt, and how cleaning relates to a technical cleanliness test.

Parts and contaminants · 4 min readUltrasonic cleaning of CNC machined parts before assemblyA machined part that goes into an assembly carries its coolant, chips and burr flakes into the product unless they come off first. What assembly asks of the cleaning step, how to lay out wash, rinse and dry around the machining cell, and how to keep the part clean between the tank and the fitter's bench.

Parts and contaminants · 5 min readRemoving machining swarf, chips and coolantTurned and milled parts carry cutting fluid and fine chips in every pocket, bore, thread and cross-drilling. Ultrasonic cleaning flushes them in one cycle. The bath, what milled parts need in particular, the filtration that makes it last, and the cleanliness checks a machine shop uses.

Industries · 3 min readUltrasonic cleaning in industrial manufacturingParts off the machining centre, the press, the grinder and the heat-treatment furnace, cleaned before inspection, coating, assembly or shipping. What a manufacturing shop asks of a cleaning tank, the cleanliness specifications that drive it, and the set-ups from a single ST tank to an MT multi-tank line.

Parts and contaminants · 3 min readCleaning automatic-transmission valve bodiesVarnish from old fluid and friction-material fines stick the spool valves, and the gearbox shifts late, hard or not at all. How rebuilders strip a valve body, keep every spool with its bore, and clean the channels and valves at 40 kHz without harming a single clearance.

Parts and contaminants · 4 min readHow to clean petrol fuel injectors with ultrasoundPort and direct injectors clog at the filter basket and the nozzle. What an ultrasonic bath cleans, why the injector has to be pulsed for the inside, which parts come off first, and the flow test that proves the result.

Parts and contaminants · 3 min readUltrasonic cleaning of diesel injectors in the workshopCarbon at the nozzle, tar from blow-by on the body, lacquer inside. How common-rail injectors are prepared, which parts go in the bath and which never do, the liquid, temperature and time, and why the test bench has the last word.

Parts and contaminants · 3 min readRemoving flux residues from circuit boards and assembliesFlux left after soldering attracts moisture, corrodes joints and leaks current between tracks. Which flux types need cleaning, the 40 kHz bath that removes them without harming components, what to keep out of the tank, and how to prove the board is clean.

Industries · 3 min readUltrasonic cleaning in electronics and PCB assemblyFlux after soldering, dust and oxide on connectors, machining residue on housings and heat sinks, particles on sensors and optics. What ultrasonic cleaning does in electronics production and repair, at 40 kHz with deionised rinses, and what must never go in the bath.

Ultrasonic cleaning basics · 3 min readDirect and indirect cleaning: parts in the bath, or in a beaker inside itDirect cleaning puts the part in the tank liquid; indirect cleaning puts it in a beaker or tray of its own liquid standing in the tank. Indirect keeps aggressive chemistry and small parts out of the main bath. When each makes sense.

Process and parameters · 2 min readParticle size removal versus ultrasonic frequencyLower frequencies make bigger, more energetic bubbles for heavy soil; higher frequencies make smaller, gentler bubbles that do better on fine particles. How to choose between 28 and 40 kHz.

Industries · 5 min readUltrasonic cleaning in the aerospace industryEngine parts, avionics, interiors, composites and precision instruments: the contaminants of aerospace maintenance and how ultrasonic cleaning deals with them.

Industries · 5 min readUltrasonic cleaning in mechanical engineering and industrial manufacturingPrecision parts, tool and die, machined components, paint and adhesive residues, rust and flux: how ultrasonic cleaning fits into a mechanical engineering shop.

Ultrasonic cleaning basics · 2 min readWhy ultrasonic cleaning reaches where brushes cannotCavitation cleans blind holes, threads and internal passages that scrubbing and soaking leave dirty. What the process is, where it is used and what to expect.
