Why Choose Laser Edge Banding over Traditional Edge Bander Techniques?

  1. Appearance: Achieve a seamless design void of any visible adhesive lines.
  2. Product Quality: Assured consistent, top-notch quality.
  3. Operational Process: User-friendly interface allowing pre-set process parameters.
  4. Performance: Improved resistance to environmental factors prolonging lifespan.
  5. Durability: With only one bonding surface, laser edge banding enhances durability, waterproofing, and resistance to common household issues like mold.
  6. Comparative Advantage: Laser edge banding outperforms the traditional edge bander methods, eliminating common problems like detachment and discoloration.

Introduction of Laser Edge Banding

By utilizing a high-energy laser beam that is reflected onto a special polymer coating on laser-specific edge banding, the ultra-thin functional layer on the edge strip quickly melts. It is then pressed onto the board through a roller mechanism. Laser edge banding can be understood as having only one bonding surface, eliminating the need for adhesive application. This achieves a seamless, gap-free result and enhances the bonding peel strength.

Laser Edge Banding - Materials

Laser Edge Banding Coating: The edge banding tape used for laser edge banding is coated with a special polymer layer, which serves as a replacement for hot melt adhesive. This polymer melts when exposed to laser irradiation, and in its molten state, exhibits excellent bonding properties.

Laser Edge Banding Tape: The material of the laser edge banding tape is the same as the material of traditional edge banding tapes, including acrylonitrile-butadiene-styrene copolymer (ABS), polypropylene (PP), polyvinyl chloride (PVC), and polymethyl methacrylate (PMMA). Laser edge banding tape replaces the traditional hot melt adhesive with a special polymer functional layer, integrating the base material of the edge banding tape and the functional layer. Simi Kitchen Cabinet Co., Ltd. uses the laser edge banding tape from the German REHAU company, with the base material made of ABS and the functional layer made of PP, which has a higher environmental performance than traditional PVC edge banding tapes.

Process Flow

The entire process of laser edge banding adopts digitalized production, unaffected by natural factors such as temperature and weather. As a result, furniture produced using the laser edge banding technique boasts consistent quality and appearance. The laser edge banding process eliminates the need for adhesive application, anti-adhesive spraying, adhesive pot heating, glue spreading, and glue scraping units. The pressure rollers and trimming knives no longer encounter adhesive residue, reducing operational and labor costs. Furthermore, it's energy-efficient and eco-friendly: there's no evaporation pollution from glue, no need for cleaning, and energy consumption is minimal when the machine idles. Laser edge banding processing requires no waiting for heating, and intermittent operation conserves energy.

 Control Sytems

  • Up to 48 sets of process parameters can be pre-stored, allowing for manual selection of the process or retrieval through the edge banding machine's output IO signal;
  • Different process parameters can be switched based on the edge banding machine's low, medium, and high speeds;
  • Features multi-layer foolproof designs, capable of receiving abnormal alerts from the edge banding machine and disconnecting the laser enable signal;
  • The oscillation mode can be chosen to start from the bottom end, eliminating the need to reposition or adjust the height axis when changing to different width edge bands.
