1. Ensure that the edge banding is straight, the surface is flat, the bottom is flat, and the thickness is uniform, otherwise the glue line will be thick and heavy or there will be a large gap after the edge banding is completed.
2. There is a certain reasonable hardness. The higher the elasticity, the better the quality, and the stronger the wear resistance. If the hardness is too high, it is not easy to use. If it is too soft, the wear resistance will be reduced, and the possibility of deformation and aging will be increased.
3. The glossiness after trimming is good, the closer it is to the complexion, the better the quality, and the whitening of the trimming is not obvious. If the whitening of the trimming is serious and the gloss is dull, it is caused by the poor quality of the materials used, which will lead to finished furniture after use. The overall color is inconsistent.
4. The back glue is evenly coated. Generally, transparent glue or white glue is the top grade. The other colors of back glue are generally domestic back glue.
