How to detect the quality of furniture edge banding?
1. Visually check whether the edge banding is consistent with the color and texture of the board used, or whether it is consistent with the designer's requirements.
2. Check whether the surface of the edge banding is smooth and flat, and whether there are any spots. If there are spots or fine pinholes, it may be made of recycled PVC.
3. Check whether the back of the edge banding is flat.
You can use a flat blade to clamp the edge banding horizontally to see if it is straight. If it is not straight, there will be thick glue lines on both sides after edge banding. If the back of the edge banding is flat, there will still be thick glue lines after edge banding. You can check it as follows: Check whether the saw surface of the board is flat. If the specifications of the upper and lower saw blades are different when sawing the board, there will be small steps on the saw surface when sawing the board, which will affect the edge banding.
4. Check whether the hot melt glue is too thick. Check whether the thickness and pressure adjusted by the edge banding machine are coordinated. Use a small section of edge banding to seal the edge, then tear it apart forcefully to check whether the bonding strength between the edge banding and the hot melt is reasonable and uniform. If the strength is insufficient, check whether the hot melt temperature of the edge banding machine meets the use standard.
5. Check whether the side of the board is uniform after trimming. If it is jagged, it may be due to the following reasons: the trimming knife is too blunt; the edge banding is too hard; the edge banding contains too much calcium carbonate. Use your fingernails or other tools to scratch the edge banding. If it is damaged, the surface wear resistance and hardness of the edge banding do not meet the standards, which proves that the quality of the edge banding is unqualified.
