Wood gluing with High-Frequency heating (HF gluing) offers considerable advantages compared to conventional techniques.
Speed: HF gluing makes it possible to dry conventional PVAC glue-lines in minutes or even seconds. When the products leave the HF press the glue is cured and the products are ready to be processed on a sawing or sanding machine.
Production quality: HF gluing advances a high quality at a constant level of the finished product because it dissipates the heat instantaneously and evenly throughout the glue-lines, without the danger of temperature-induced material stress. In addition, HF wood gluing encourages fully automated production lines, which results in a stabile production quality and quantity.
Versatility: HF gluing can be used with most modern types of adhesives, such as PVA, PVAC, melamine/urea, resorcinol and certain PU-isocyanate-based adhesives; and with all types of wood: gluing the numerous and often difficult tropical species of hardwoods is no problem. Consequently, HF wood gluing is used in a large range of applications: lamination, edge-lipping, endless gluing, finger-jointing for the production such as panels, stair-beams, doors, table tops and legs etc.
Economics: HF gluing saves space, because it allows a high production rate at an installation with a small footprint. HF gluing saves on employee costs, because installations can be run completely automatic.
