Targeted activation for reliable connections

Surface activation for perfect adhesion

The product family

Efficient surface activation - with a system

A high-quality coating begins with an optimally prepared surface. Surface activation from Venjakob specifically increases the surface energy and ensures that paints, adhesives and films adhere securely in the long term - regardless of the material and geometry.

As an experienced system provider, we integrate our activation processes seamlessly into automated production lines. This results in energy-efficient, economical and reproducible processes - perfectly tailored to industrial requirements.

VEN ACTIVATE surface activation systems

Maximum precision

The VEN ACTIVATE surface activation systems are designed for maximum flexibility and precision. Their modular design allows them to be adapted exactly to the material, cycle time and line layout - from compact individual stations to fully automated inline solutions. With robust system technology, digital process control and maintenance-friendly design, they ensure permanently reproducible activation results - for consistent adhesion and high system efficiency.

The advantages of surface activation

All Venjakob activation processes are chemical-free, energy-efficient and low-maintenance. They not only improve adhesion, but also reduce the use of primers and solvents - a clear advantage in terms of environmental compatibility and cost-effectiveness.

  • High process reliability thanks to reproducible results
  • Low energy consumption with maximum activation effect
  • Less waste and rework
  • Sustainable alternative to chemical treatments

Surface activation technologies

Venjakob relies on two tried and tested processes for optimum adhesion: Flame treatment and plasma activation. Which method is used depends on the material, geometry and process speed.

VEN ACTIVATE FLAME

Flaming

Operating principle
Short, controlled flame exposure oxidizes non-polar molecules and removes organic residues.
Areas of application
Ideal for plastics, foils, profiles and flat workpieces.
Process temperature
High temperature, very short reaction time.
Process integration
Inline-capable, robust, low-maintenance, very short cycle times.
Energy efficiency
Low gas consumption, high processing speed.
Special features
Proven technology with high process stability and easy handling.

VEN ACTIVATE PLASMA

Plasma activation

Operating principle
Ionized gas (plasma) changes the surface structure and creates polar groups that improve adhesion.
Areas of application
Particularly suitable for temperature-sensitive materials, complex geometries and selective activation.
Process temperature
Low temperature, gentle treatment without thermal stress.
Process integration
Inline-capable, precisely controllable, can be flexibly combined with cleaning and coating systems.
Energy efficiency
Electrically operated, precisely controllable, reduced overall energy requirement.
Special features
Modern, controlled process with reproducible activation performance and digital monitoring.

Both processes are an integral part of the Venjakob pre-treatment systems. Flame treatment impresses with its speed and robustness, while plasma activation enables maximum precision for sensitive materials. This means that every workpiece can be optimally prepared for subsequent coating steps.
