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 readUltrasonic cleaning of battery components before assemblyCell cans, lids, tabs, busbars, housings and cooling plates carry oil and particles into welding and bonding. How to clean them; cells never go in a bath.

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 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 electronic parts before assembly with ultrasoundHousings, heat sinks, shields and frames carry oil, chips and fingerprints into the device. How to clean them first, and why conductive particles matter.

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 industrial filters for reuseStainless mesh, sintered metal and wire-wound filters can be cleaned and reused many times; paper and felt cannot. Which filters are worth cleaning, how to get the dirt out of the depth of the medium rather than just its surface, and how to prove a cleaned filter is fit to go back into service.

Parts and contaminants · 4 min readUltrasonic cleaning of bearings and mechanical componentsOld grease, wear particles and dirt out of dismounted bearings, gears and couplings so they can be inspected and reused. Which bearings to clean and which never to wash, the settings, and the steps that stop a clean bearing from rusting or being damaged before it is greased again.

Parts and contaminants · 4 min readCleaning hydraulic valves and manifold blocks with ultrasoundA hydraulic manifold is a block of intersecting drillings, and every one of them must be free of chips, burr flakes and coolant before oil touches it. The cleaning sequence after deburring, the cleanliness targets, the equipment for new blocks and for repaired valves, and how to keep the clean block clean until it is plugged.

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.

Parts and contaminants · 2 min readCleaning porous materials with an ultrasonic cleanerSintered filters, castings and open-pore materials trap soil where liquids barely flow. How cavitation gets in, and where it cannot.
