How ultrasonic cleaning fits between dismantling and disinfection, the chemistry that protects stainless, the mistakes that make it rust, and how the result is verified.

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 · 3 min readUltrasonic cleaning of packaging equipment componentsFilling nozzles, dosing pistons, forming sets, sealing jaws, cutting knives and vacuum cups collect product, film residue and dust between format changes. Which packaging parts are cleaned in an ultrasonic tank, how to treat heat-sealing jaws and coated parts, and how cleaning fits a format or allergen changeover.

Parts and contaminants · 4 min readUltrasonic cleaning of knives in food processing plantsHand knives, steels, scabbards and knife baskets collect fat and protein in the handle joint and along the edge, where a quick rinse leaves them. How a knife-cleaning station with an ultrasonic tank fits the shift, the temperatures that keep protein from baking on, and the steps before disinfection.

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.
