On the cutting edge
Toto’s Laser edging Door technology reflects the state of the art in the edge banding process of melamine doors. Featuring seamless joints, superior adhesion strength, and increased heat and moisture resistance, the Laser Edging Door is strong and durable. Its smooth transition between surface and edge becomes a prominent feature of the door, allowing the creation of a perfect seamless covering panel.
Unlike the usual edge banding process, which needs glue to stick a band onto a work piece, the new technology makes use of laser beams to melt the polymer layer of the band to become an adhesive for itself. The beam is deflected over the entire surface of the band through an oscillating mirror. Once melted, the band is pressed directly onto the work piece. This method brings more benefit than aesthetics, as it creates a melamine door with superior adhesion strength and higher resistance to heat and moisture.
The joint line in the Laser Edging Door is almost invisible and seamless since it does not require any glue which is known to be the cause of the obvious edge line. As the result, although it is actually a melamine door, it will seem as if it comes as a single entity - one piece of wood without any joint.
When the laser beam is radiated to a band, the melted polymer will penetrate into the structure of the work piece and create a considerably stronger adhesion between the two materials compared to the glue-based technique. This way, the edges are more durable and will not peel. Since glue is not needed, the band will directly bond with the work piece, leaving no gap for any moisture or heat to infiltrate.
