Ultrasonic medical equipment parts cleaning

Lake Region Medical GmbH needed a cleaning process that causes no damage to the product while meeting stringent specifications on the removal of particulate, film-type, and microbiological contaminants.

Ultrasonic Cleaning Machines (UCM AG) of Switzerland responded with an ultrasonic fine-cleaning system that provides reliable cleaning of more than 1 million stainless steel turned parts and tubes per day, six days a week – with products being discharged directly into a good manufacturing process (GMP) Class D cleanroom.

In 2013, a Lake Region Medical customer from the pharmaceutical/med-tech sector needed to expand cleaning capacity for stainless-steel turned parts and tubes. The company decided to outsource this operation to Lake Region Medical. Under the contract, the equipment required for this process had to achieve given levels of cleanliness – with limits on particulate, film-type, and antimicrobial contaminants – while also ensuring that the parts would emerge from the cleaning process undamaged. An additional challenge resided in the product geometry. The turned parts – measuring up to 10.0mm in diameter – have very fine drilled holes. The tube parts are up to 60.0mm long, with internal diameters of only 0.4mm, and must be consistently and reliably cleaned inside.
