InfraWeldThrough-transmission IR welding
Through-beam welding at the IR spectrum
Innovative through-transmission infrared welding in a compact package. This technology uses focused IR light energy to replace adhesives. Useful in both linear and spot welding applications.
Discover the InfraWeld process
The InfraWeld process uses infrared energy to bond a transparent or translucent material to a compatible opaque material with through-transmission welding. This process is different than laser welding. Lasers produce energy intensely focused on a fine point. Conversely, the InfraWeld process heats a focal area with less intense energy making it a safe, efficient, and versatile technology. Laser welding applications are typically full perimeter welds for hermetic seal specified assemblies. InfraWeld is better-suited for linear area bonding, spot-welding applications, and unique full circumference bonding of medical tubing components.
1 – Clamp
The module extends and clamps the components together creating an airtight seal around the weld area.
2 – Heat
Reflective surfaces inside the module focus the IR energy from a technical-grade halogen lamp and direct it toward the weld interface. The energy transmits through the top part and is absorbed by the surface of the lower part, commonly referred to as through-transmission infrared (TTIR).
3 – Bond
Air pressure inside the module forces the two softened components into each other. After the lamp is turned off, the module continues to clamp and apply pressure to the weld allowing the materials to bond.
4 – Cool
The module retracts slightly, and cooling air is blown over the weld. The result is a robust joint that is stronger than the parent strength of the headliner itself. Typical cycle times are 10-25 seconds.
