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 · 4 min readCleaning threaded parts and blind holes with ultrasoundTapped holes, blind bores and internal threads trap chips, coolant and air. Why the trapped air is the real enemy, how part orientation, degassing and movement get the liquid in, which frequency suits fine threads, and how to get the liquid out again.
