Passivation systems
Passivation systems – batch-clean passivation after the electroplating process
WMV passivation systems are fully automatic, media-independent and reduce media carryover by 92% after each process step. This makes them an important component that supports you in using resources more consciously – and producing more efficiently.
Passivating bulk material in the centrifuge – brilliant results with minimal use of resources
Passivation systems with WMV centrifuge technology can perform any passivation – regardless of the passivation chemistry. They are suitable for all metals and every industry – with responsible use of resources. This is made possible by the rapid centrifuging of the media in the centrifuge bowl. At speeds of up to 750 rpm, media carryover is reduced by 92%. In addition, after centrifuging, the excess medium is returned to the original container and reused. Almost no coating material is lost. And the service life of the passivation tanks is increased: you save costs for energy and chemicals – with the highest purity and quality of your parts.
Clean and gentle – passivating and coating in just one drum
In WMV passivation systems, the goods for subsequent TopCoat coating or sealing are already in the drum. This means that the parts do not need to be transferred. Any resulting damage is eliminated. Whether passivation with or without subsequent coating or drying: all the necessary process steps are particularly gentle and are carried out on a batch-by-batch basis.

Fully automated processes – for maximum specification and reproducibility
We have fully customized and automated the passivation process for our passivation systems. This has many advantages:
- High flexibility: Recipes are freely selectable. They meet quality requirements for a wide range of parts.
- Full process reliability: statistics can be called up at any time. Processes are logged and documented. This ensures the quality of your processes and results.
- High reproducibility: Perfect coordination of material and chemistry ensures that you meet all quality requirements. Automated processes ensure that you can rely on the consistently high quality of your parts.
- Reduced rinse cycles: In most cases, 3 rinse cycles can be reduced to 2 by spinning off.
“Always a winning combination” – suitable passivation systems for every system size
From 20 kg/hour to 4 tons/hour: The modular WMV system design makes it easy to integrate the right passivation systems for small and large electroplating systems. Regardless of the manufacturer. Including: the energy-efficient WMV centrifuge technology and fully automated processes. This is how we help you to remain competitive and achieve your climate targets – whenever you want.

Questions & Answers
Is the passivation step necessary for all parts in the electroplating process?
This varies from case to case. Passivation can be the last step in the electroplating process or an important step in preparation for subsequent surface finishing.
How flexibly can your passivation system be integrated into our electroplating processes?
Thanks to their modular design, our systems are completely flexible in terms of adaptability and recipe for all parameters and any process sequence.
For which components and surface finishing processes are your passivation systems suitable?
Bulk goods and rack goods can be passivated in our systems. They are suitable for all operators of electroplating systems in contract coating and parts production as well as for in-house coaters.
