What is edgebanding? Edgebanding is the process of sealing the cut side of a panel, and is one of the most important processes in the production of panel furniture. It is the most important process in the production of panel furniture. The edge banding is glued to the cut side of the panel to seal the panel. The function of edge sealing is mainly to decorate and insulate the air, prevent moisture and moth, thus increasing the service life of the product.
1. The role of edge sealing
Edge sealing technology, is derived from the prevalence of panel furniture, its role is mainly to protect the substrate, to prevent the entry of water seal, as well as to close the release of harmful gases, enhance the stability of the product ... But because the board furniture in the cut open material, the side will be visible "prototype", like multi-layer board will reveal layers of overlapping sides, does not meet our standards for the face of the furniture. So, edge sealing also has an important role: is to enhance the appearance of furniture.
At present, office furniture mainstream edge sealing technology has the following three.
- Hot melt glue edge sealing: through the melting equipment, the heated and melted hot melt glue evenly coated on the plate, after cooling the plate and edge sealing strip naturally bonded together, so as to achieve the combination of plate and edge sealing tape.
- Hot air edge sealing: through the high temperature nozzle of the hot fan, the use of compressed air generated by the heat, the edge sealing strip on the coated glue melted to achieve office furniture edge sealing effect, which is a modification of the hot melt adhesive edge sealing technology, although the efficiency will be higher, but the material is still hot melt adhesive and adhesive containing volatile hazardous substances.
- Laser edge sealing: through the action of the laser, the edge band pre-coated functional layer melted, followed by a pressure wheel mechanism will be tightened edge band, and finally after the flush, trimming, tracking chamfering and other processes to complete the edge sealing.
2. Advantages of laser edge sealing
Seamless link, more beautiful, especially for white and other light-colored door panels and acrylic and other transparent panels, and laser edge sealing, the color of the functional layer hardness and the surface layer of the edge band are the same, so it can realize seamless edge sealing. The product quality is more stable, heat resistant, moisture resistant, mold resistant, high added value, healthy and environmental protection, and prolong the service life of the product.
Laser constant temperature welding system operation process
The computer software sets the welding parameters and sends out the welding command, the laser module emits the laser and processes the product through the semiconductor thermostatic coaxial monitoring welding head, the infrared thermometer collects the welding point temperature at high speed and feeds the signal to the laser power controller, the laser power controller carries out high-speed PID algorithm to automatically adjust the laser power of the laser pump source and carry out constant temperature welding processing of the welding point.
Compared with other edge sealing technology, the advantages of laser edge sealing technology are: in the operation of the equipment, you can set your own program, semi-automatic operation, the operation process can be switched between the edge sealing bar; no hot melt adhesive, edge sealing machine comes with activation coating, can achieve a permanent and seamless functional bonding, not easy to crack, more solid than ordinary edge sealing; has a moisture-resistant, mold-resistant, high temperature, wear-resistant, yellowing-resistant stable function The operation process does not require preheating, no glue, more green and environmental protection.
