RotoVAC product description
Tantec RotoVAC vacuum plasma treater is designed for plasma treatment of small injection moulded plastic parts, without the need to place them in a jig or use complicated handling systems.
With the RotoVAC drum design, simply fill the drum and place it in the vacuum chamber. The rotation will ensure that all parts are treated.
In the treating chamber a vacuum builds up to between 0,1 and 4 mbar before an electrical discharge is created through the integrated plasma electrode. Treatment cycle times are often short, between 20-180 seconds depending on the material and its formulation.
The RotoVAC plasma treater is appreciated for its simplicity of operation, reliability in production and fast process speed. Treating gasses such as argon and oxygen can be applied, but in most cases this is not necessary due to the high power exposed by the plasma discharge. RotoVAC uses the advanced Tantec power generator HV-X series as power supply, and specially designed plasma transformers to provide voltage to the plasma electrodes.
The rotating drum ensures that all parts are equally treated. The concept includes an extra drum which can be loaded during treatment and simply exchanged with the one in use when the batch is completed.
Standard RotoTEC-X
This product is manufactured as a standard machine to match common
production requirements. It offers a proven configuration with defined
footprint, treatment concept and machine interface, making it easy to
integrate into industrial production.
Customized RotoTEC-X
This product can be customized to fit your production. Tantec can adapt
the solution to your part geometry, process requirements and production
flow, including footprint, cycle time, chamber size, part capacity and
machine interface.

FAQ
What is RotoVAC used for?
RotoVAC is a vacuum plasma treater with a rotating drum for rotationally molded plastic parts and 3D parts. It helps you create a more reliable process before the next production, assembly or quality step.
How does RotoVAC work?
RotoVAC uses vacuum plasma treatment inside a chamber, where the drum rotates during the process. This ensures that the surface or component is treated in a controlled and repeatable way.
Which materials or components can be used with RotoVAC?
RotoVAC is suitable for rotomolded items, small plastic parts and 3D parts. The final setup depends on the material, geometry and production requirements.
Can RotoVAC be integrated into production?
Yes. RotoVAC can be used as a chamber-based treatment step before bonding, coating or printing. This makes it suitable for both new production concepts and upgrades of existing processes.
What production challenge does RotoVAC help solve?
RotoVAC helps solve challenges related to low surface energy, poor wetting and unreliable adhesion. It supports a more stable result before the next production step.
How does RotoVAC support consistent quality?
RotoVAC supports consistent quality through uniform activation on complex surfaces and improved adhesion quality. This helps reduce variation and makes the process easier to document and repeat.
What are the key advantages of RotoVAC?
Key advantages include chamber treatment for large parts and controlled vacuum plasma processing. These features make RotoVAC practical for industrial use where uptime, control and repeatability matter.
When should you consider RotoVAC?
You should consider RotoVAC when adhesion, printing, coating, bonding or surface preparation is critical to product quality. It is especially relevant when untreated surfaces create unstable results.
Is RotoVAC an environmentally friendly solution?
RotoVAC supports a cleaner production process by reducing the use of chemical pre-treatment or primers where the application allows it. The process is dry, controlled and repeatable.
Can RotoVAC be delivered as a standard or customized solution?
Yes. Tantec can provide RotoVAC as a standard solution or adapt it to your product, material, geometry, line speed and process requirements. The final configuration is selected together with you.
