In-House Cleaning and Surface Treatment

Enhance System Performance

At Pfeiffer Vacuum Valves & Engineering, we prioritize the quality and cleanliness of every component. All stainless steel products undergo meticulous cleaning processes to ensure optimal performance. Here's what our cleaning process entails:

• Passivation: Stainless steel parts are treated in a light acid solution to eliminate weld scale and oxide buildup.
• Detergent Wash: We use biodegradable detergents to remove machine lubricants, followed by a thorough washing and rinsing with deionized water.
• Customized Cleaning: We understand that different projects have unique requirements, that's why we offer tailored cleaning recipes to meet our customers' specifications.

Passivation	Detergent Wash	Deionized Water Rinse

For critical production parts, such as valve bodies or components for semiconductor equipment, we employ chemical cleaning. This involves immersing the component in carefully controlled chemical baths, followed by rinsing with deionized water and drying with filtered hot air. Chemically cleaned parts are then promptly sealed in clean room bags to maintain their pristine condition.

Surface Treatment Solutions For Stainless Steel Vacuum Components

In addition to cleaning, we offer a range of surface treatment options to enhance the durability and performance of vacuum components:

• Tumbling: Our tumbling process, using ceramic media, effectively deburrs components while ensuring a uniform finish.
• Bead Blasting: Glass shot bead blasting is employed to clean, hone, polish, and peen surfaces, removing any remaining scale.
• Electropolishing: This advanced electrochemical process is the pinnacle of surface treatment for stainless steel vacuum components. Electropolishing not only removes surface imperfections and burrs but also passivates and relieves stress in the material. This results in a smoother surface finish with a significant reduction in friction and surface area.

Electropolishing is particularly crucial for vacuum chambers because it improves the pump-down speed and conductance. This process selectively removes material from the surface, and leaves stainless steel enriched in chromium and nickel which minimizes outgassing rates and ensures the highest level of vacuum integrity.

At Pfeiffer Vacuum Valves & Engineering, our commitment to excellence extends to every aspect of our processes, guaranteeing superior quality and performance for our customers.
