Passivation Systems Case Studies - Case Studies

Case Study: Bringing Citric Acid Passivation In-House for Stainless Steel Medical Device Parts

Stainless steel passivation, citric passivation

Citric Acid Passivation for Precision Stainless Steel Components For manufacturers working with stainless steel medical device parts, corrosion resistance is not just a finishing detail. It is part of product performance, quality control, and customer confidence. Small stainless steel parts such as cannulas, surgical tubes, guide components, fittings, and machined instruments may look clean after […]

Automated Passivation for High-Volume Production: Case Study

rail mounted gantry crane automation

Streamlined Throughput for Demanding Stainless Steel Applications When manufacturers reach a production scale where manual passivation simply can’t keep up, automation becomes essential. For one high-output stainless steel component manufacturer, Best Technology delivered a customized Automated Passivation System for High-Volume Production designed to maximize throughput, minimize operator strain, and maintain full compliance with ASTM A967, […]

Semi-Automated Inline Citric Passivation Solution with Data Tracking

Wet Bench for Citric Passivation with Data Tracking

For one medical device manufacturer, the design of a citric passivation solution faced two major challenges: The manufacturing process required performing a water-break test after cleaning parts, before proceeding to passivation. This meant that they could not use a fully automated passivation solution. The system had to have data tracking for quality control purposes. Semi-Automated […]

Automated Pipe Cleaning and Acid Passivation System

Automated pipe cleaning passivation system

Pipes and tubes often are difficult cleaning and passivation applications because various washing, rinsing, and passivation solutions must be flushed through the pipes. Pipe flushing applications with tight aspect ratio (high length vs. the internal diameter) or multiple bends tend to require forced or pumped circulation through the tubing. Pipe Passivation System Video   Passivation […]

Automated 6-Stage Wash-Rinse-Passivate-Rinse-Rinse-Dry For Aerospace Customer

Automated Passivation System

Time and time again we hear from customers looking to transition their passivation process in-house.  In most cases the biggest concern cited is not always the cost to have the process performed by an external vendor, but the time.  Between packing, shipping, unpacking, processing, repacking, shipping the parts back and unpacking them again many customers […]

Manual Bench Top Ultrasonic Passivation Equipment

Manual Benchtop Passivation

Flexibility is a key concept which your customers demand from you each day, and with the 782P series bench top ultrasonic passivation 5 tank system, flexibility is built-in. From washing and rinsing to passivating and drying, the 782P benchtop parts washer can handle any task you throw at it. The 782P provides 4 separate 3.5-gallon ultrasonic tanks (12″ […]

Medical Device Cleaning and Passivating Equipment with a Cleanroom Space Constraint

Automated-Cleaning-Passivation-Equipment-Clean-Room-Space-Saving

Cleanroom Medical Device Cleaning Equipment Background Large medical device manufacturers have outsourced much of their manufacturing to contract manufacturers for a long time. It’s always exciting to see small businesses succeed and grow. But sometimes business growth can lead to growing pains. Such was the case with a growing medical device manufacturer in Minneapolis recently. […]

Heated Polypropylene Acid Passivation and Rinse Tanks

Polypropylene Passivation Tanks Front View

Application for Heated Acid Passivation and Rinse Polypropylene Tanks Recently Best Technology was contacted by a customer who manufactures and installs stainless steel piping into underground water distribution systems. Once buried, the pipes need to have a very long life. The customer uses stainless steel fittings and junction pieces throughout their buried systems. The fact that the […]

Electropolishing Wet Bench with Nitric Acid Neutralization / Passivation

Electropolishing Wet Bench System with nitric acid passivation

Acid Neutralization Application The medical device electropolishing wet bench has multiple polypropylene tanks to electropolish, rinse, nitric acid passivate / neutralize, and 2 final cascade overflow rinse tanks. This electropolishing wet bench has incoming parts already cleaned so electropolishing is the first stage.  Other wet bench systems can have part cleaning and rinsing before the […]

Automated Ultrasonic Citric / Nitric Acid Passivation Equipment for Medical Device and General Parts

Automated Passivation Equipment Nitric Acid Passivation

Application for Medical Device Passivation Case Study The automated ultrasonic passivation system processes medical device industry parts with precision part cleaning and nitric or citric acid passivation after machining and/or laser mark. The system is able to passivate the following grades of stainless steel: 17-4, 304, 316, various 400 series and the like with a neutral […]
