Innovative Cleaning Processes in the Manufacture of Medical Products

New products and production processes enable the manufacture of complicated geometries. This in turn poses enormous challenges for cleaning technology.

In this joint project, novel cleaning processes such as CO2 snow jet cleaning, plasma cleaning and an aqueous cleaning process were investigated for their applicability, performance and suitability for medical technology.

The focus was on medical technology products and in particular on difficult-to-clean sub-areas such as blind holes, undercuts or cannula bores with a large length/diameter ratio. Cleaning was also considered in connection with the targeted functionalization of material surfaces prior to further processing.

For use in medical technology, the validability of the process is of great importance, which is why a cleaning analysis with evaluation was developed. The purity was evaluated by photoelectron spectroscopy (XPS).
