资讯概要: Edge banding is an indispensable step in wooden door manufacturing, and the edge-banding process directly affects formaldehyde emissions. If the edge-banding machine is of poor quality or the process control is inadequate, the edge-banding strips are likely to warp after a few years. So, what are the different types of edge-banding processes? And how can we distinguish among these various edge-banding techniques?

  Edge banding is an indispensable step in wooden door manufacturing, and the edge-banding process directly affects formaldehyde emissions. If the edge-banding machine is of poor quality or the process control is inadequate, the edge-band strips are likely to warp after a few years. So, what are the different types of edge-banding processes? And how can we distinguish among these various edge-banding techniques?

  Hand-sealing edges: When carpenters make furniture on-site, they generally seal the edges by hand. The results vary from person to person, each with its own unique charm.

  EVA edge banding: Using EVA hot melt adhesive, this method represents an improvement over manual edge banding and allows for assembly-line production. However, it has poor heat resistance, tends to peel off over time, and requires a large amount of adhesive, resulting in noticeable glue lines on the surface of the edge banding strip!

  PUR edge banding: This method uses PUR hot-melt adhesive and is currently the most widely adopted mainstream technology! However, it has certain requirements for the processing environment, and the equipment cost per unit is relatively higher than that of EVA. As a result, small-scale factories generally can’t afford to adopt this technology. In short, it’s the ultimate in cost-performance ratio!

  Laser edge sealing: Seamless edge sealing—no glue lines visible! This is currently the latest and most environmentally friendly technology. However, due to its highly advanced nature, the technology is not yet fully mature, and its performance remains relatively unstable.

  Common edge-band techniques can be categorized into two types: one is adhesive bonding technology, and the other is hot-melt seamless technology.

  EVA adhesive exhibits reversibility under high temperatures or when submerged in water, whereas PUR adhesive is irreversible. Therefore, in high-temperature or humid environments, boards sealed with EVA adhesive are prone to edge lifting, while boards sealed with PUR adhesive generally do not experience edge lifting during use.

  Ultra-aggregated PUR edge-band sealing technology features a glue line of approximately 0.01 mm—just one-third the size of conventional methods. After being submerged in water for 24 hours, no swelling was observed, making it suitable for a wide range of environments.
