A REVOLUTIONARY CONCEPT BECOMES THE MOST POPULAR TECHNOLOGY FOR THE INVISIBLE JOINT METHOD

In 2011, when the revolutionary method was presented for the first time at the Ligna Trade Fair, the visitors saw the product work efficiently at machine speed of 10m/min.
Less than a year later, at the turn of the year 2011/2012, the first industrial machine started production at 20m/min.
Meanwhile, customers are offered machines working at 30m/min and more as well as retrofits for machining centres.

INVISIBLE JOINTS

Invisible joints are the edge quality of the future. Besides, with qualities like high stability, better heat and moisture resistance and as well as anti-bacterial properties invisible joints are already dominating the market as compared to conventional bonding methods.

WHAT CAN CUSTOMERS EXPECT FROM THE HOT AIR SYSTEM?

  • The Hot Air System offers you a cost-effective alternative to all the known methods in the market.
  • The Hot Air System is easy to maintain and reliable.
  • You can retrofit the Hot Air System to any existing edge bander or machining centre.
  • The System works by and large independently of the existing edge bander.

ADVANTAGES AT A GLANCE

Advantages of laser edging:

  • More satisfied customers due to high quality.
  • Immaculate look, especially in high-gloss décor.
  • No staining/discolouring of the joint. No hot-melt adhesive is used in laser edging; instead, the functional layer is made of a polymer.
  • The reactive functional layer is colour-matched to the edge; thus, the optical invisible joint is achieved continuously.
  • High holding force of laser-cut edges (pull-off force between 25 and 48 N/cm as compared to 25 N/cm in hot-melt adhesives).
  • Significantly higher heat resistance (= the temperature at which the edge begins to come off of the board).
  • The heat resistance of laser-cut edges lies between 120-150 °C, depending on the edge manufacturer; in edges applied with hot-melt adhesives the value is between 80-90°C.
  • Considerably better resistance to moisture (on a scale of 1-100, EVA adhesives are at approx. 30-25, laser-cut edges at approx. 70-80 and PU glues are at approx. 90).
  • More efficient and economic production. There is no need to refill or control the glue flow, or set the glue quantity, or clean the glue pot.
  • It is possible to quickly switch between various edge décors in the edge bander, as there is no need for changing different glues due to the coated functional layer.
  • Competitive advantage, especially for tendering. Laser-cut edges are increasingly in demand by architects.
  • Higher market prices can be achieved.
Advantages of the Hot Air System for small trade and industry:

  • No major new investments needed. Any existing stationary edge bander and machining centre can be retrofitted with the Hot Air System.
  • The Hot Air System has a small footprint.
  • It does not interfere with the machine controls. The Hot Air System operates independently and has its own controls.
  • It is possible to process all laserable edge types, be it ABS, PP, melamine or veneer edge.
  • No specially trained safety inspector needs to be present while operating the Hot Air System.
  • After retrofitting the Hot Air System, laser-cut edges and also conventional hot-melt adhesive edges can be processed with the edge bander. With a few simple operations, you can switch between the different systems within a few minutes without any problems.
  • The changeover between production processes is possible without any tools.
  • The Hot Air System costs between €25,000 – 50,000, including installation charges, depending upon feed rate and machine type of the edge bander.
  • While positioning new edges, the edge bander setting can be adjusted simply using the components feed rate, air pressure and temperature. As a rule, you can arrive at an optimum setting after a few test runs.
