Medical Device Automated Ultrasonic Stainless Steel Part Cleaning & Passivation Systems

System Description |Common Applications |Common Configurations |Case Studies

Our automated ultrasonic stainless steel cleaning / washing and passivation systems (nitric or citric acid) are well accepted for medical device electropolishing.  The fully automated ultrasonic passivation equipment performs cleaning-rinsing-passivation-rinsing-drying by moving the fluids from heated storage tanks into a single ultrasonic process tank, rather than moving the parts basket through a series of tanks.

The entire process required to clean, rinse, passivate, rinse, final rinse and dry stainless steel metal parts is performed at the push of a button with user defined cycles of time, temperature, etc via touch panel screen driven by a PLC. The PLC computer-controlled fill-and-drain sequence to cycles parts through the cleaning, rinsing, passivating, rinsing and hot air drying processes; all within a single chambered unit.

Modular heated storage tanks allow for re-use of detergents, passivation acid and rinse water. This closed loop system configuration removes operator interaction, variability and eliminates exposure to alkaline cleaning and passivation acid chemicals. The end result is higher quality cleaned and passivated parts with tighter process controls which can be easily validated for regulated products like medical devices.  The operator simply puts dirty, dry parts in, hits start and returns to cleaned, passivated and dry parts.

We move the fluids NOT the parts! This results in Savings of nearly 50% of system cost over traditional multiple processing tanks with overhead basket carrier automation.

Common Applications for Automated Stainless Steel Passivation Systems

Typical Configurations for Automated Stainless Steel Passivation Systems for Medical Device Electropolishing

The automated ultrasonic passivation system configurations below are most common, but systems of any size from 3.5 to 100+ gallon and 1 foot to 15 foot long can be fabricated based on customer application for little to no custom costs. Systems can contain pH and conductivity meters to monitor wash, acid and rinse solutions.
