Flame Treatment
Thermal surface activation for plastics and composite materials.
Surface Activation Technology
Flame Treatment
Flame treatment is a thermal surface activation process used to increase the surface energy of plastics and composite materials. By exposing the surface to a controlled oxidizing flame, organic contaminants are removed and polar functional groups are formed on the surface, resulting in improved wettability and adhesion for subsequent painting, coating, or bonding processes.
The flame system adjusts flame parameters such as gas flow, air ratio, burner distance, and treatment speed based on part recognition and predefined process parameter. Automated part identification enables the selection of appropriate process parameters for different component geometries, ensuring reproducible surface activation without manual changeover.
Why Choose Flame Treatment
Key Benefits
Flame treatment is a proven and cost-efficient surface activation method that increases surface energy through controlled thermal oxidation, particularly suitable for non-polar polymer materials.
- —Controlled flame geometry and exposure time for reproducible surface activation
- —Well suited for low-surface-energy polymers such as polypropylene (PP) and TPO
- —High process speed enabling inline integration in automated production lines
- —Cost-effective improvement of adhesion for painting, coating, and bonding processes
- —Automated part identification with optimized parameter
- —Significant reduction in setup and changeover time compared to manual adjustment
