Ultrasonic and VCN Cleaning

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

Up until now, we have only been able to use external cleaning methods to clean our parts. When we are challenged with removing oils, grease, or other contaminants within pores, dead-end holes, or tubes, ultrasonics or jet spray are generally our best choice.

Ultrasonics, since sonics cannot penetrate solid surfaces, and sprays are line-of-sight cleaning methods. If we cannot see the contaminant, we usually don’t clean it. Treatments following cleaning, such as passivation, sterilization, and other surface treatments, are ineffective on dirty internal surfaces.

When interior cleaning of your part is required, we recommend using the VCN process with our ultrasonic cleaning system.

The video demonstrates how combining VCN and ultrasonics into a single unit can clean both the inside and outside of your part. We usually subject your part to the VCN process first. After the typical VCN processing for 1 to 2 minutes, an ultrasonic cycle completes the cleaning. For difficult parts, alternating one to two-minute VCN and ultrasonic cycles is recommended.
