Ultrasonic and VCN Cleaning

Combine Ultrasonics with the VCN process to clean your part inside and outside.

Thus far, our cleaning protocols have depended exclusively on external methods. For the removal of oils, greases, or other contaminants embedded within pores, blind holes, or tubular passages, ultrasonic cleaning and high-velocity jet spray systems are predominantly the most effective techniques.

Ultrasonic cleaning processes are highly effective due to the ability of ultrasonic waves to penetrate certain materials, in contrast to conventional spray techniques that depend on direct line-of-sight contact. Subsurface contamination that is not visually detectable is frequently neglected during standard cleaning procedures. Subsequent surface treatments—such as passivation, sterilization, and other modifications—are generally rendered ineffective on contaminated internal surfaces unless the cleaning process has been executed thoroughly and prior to these treatments.

For the internal cleaning of your component parts, we recommend utilizing the Vacuum Cycling Nucleation (VCN) process in conjunction with our ultrasonic cleaning system to optimize contaminant removal and surface purity.

The illustration demonstrates the integration of Vacuum Cycling Nucleation (VCN) with ultrasonic cleaning within a consolidated system, facilitating comprehensive decontamination of both internal and external surfaces of the component. The process commences with the application of VCN for approximately 1 to 2 minutes, utilizing cyclic vacuum pulses to induce nucleation sites and detach contaminants. Subsequently, ultrasonic cleaning cycles are employed to enhance particulate removal and biofilm disruption. For components with complex geometries or substantial contamination levels, an alternating protocol of 1- to 2-minute VCN cycles followed by ultrasonic cycles is recommended to maximize decontamination efficacy.
