With NIR technology ("Near Infrared Radiation"), so-called zero joints are achieved in furniture and interior design when coating the narrow surfaces of workpieces.

The light waves of the NIR radiation have a similar wavelength to the light waves of the diode lasers used for edge banding (see edge banding with laser technology). Absorbers in the functional layer absorb the energy, causing them to heat up and melt the plastic.

The NIR unit is located immediately before the pressure zone, where the rollers press the edgeband with the liquefied functional layer against the workpiece plate.

NIR compared to laser and hot air technology

The energy consumption of NIR units is lower than that of laser and hot air units.

NIR radiation can be generated at a precise time. It is therefore possible to switch off the module in gaps between workpieces.

The NIR unit works noiselessly, whereas the air exits with high volume in hot air units.
