Why Edge Banding Turns White After Edging - Is It the Board‘s Fault?397

As a professional edge banding strip manufacturer in China, we often encounter customers who complain that the edge banding strip turns white after edging. In most cases, the problem is not with the board, but with the edge banding process itself. Here are some of the most common reasons why edge banding turns white:

1. The Edge Banding Strip Is Not Properly Glued

If the edge banding strip is not properly glued to the board, air bubbles can get trapped between the two surfaces. When the edge banding is heated, these air bubbles expand and cause the edge banding to turn white. To prevent this, make sure to apply a sufficient amount of glue to the edge banding strip and press it firmly against the board.

2. The Edging Machine Is Not Properly Adjusted

If the edging machine is not properly adjusted, it can cause the edge banding to be cut too thin. This can also cause the edge banding to turn white, as the thin edge banding will not be able to properly cover the edge of the board. To prevent this, make sure to adjust the edging machine so that the edge banding is cut to the correct thickness.

3. The Edging Machine Is Not Set to the Correct Temperature

If the edging machine is set to too high of a temperature, it can cause the edge banding to burn. This can also cause the edge banding to turn white, as the burned edge banding will be brittle and weak. To prevent this, make sure to set the edging machine to the correct temperature for the type of edge banding strip you are using.

4. The Edging Machine Is Not Clean

If the edging machine is not clean, it can cause the edge banding to become contaminated with dust and debris. This can also cause the edge banding to turn white, as the dust and debris will prevent the edge banding from properly adhering to the board. To prevent this, make sure to clean the edging machine regularly.

5. The Board Is Not Properly Prepared

If the board is not properly prepared, it can also cause the edge banding to turn white. For example, if the board is too wet, it can cause the edge banding to absorb moisture and swell. This can also cause the edge banding to turn white, as the swollen edge banding will not be able to properly adhere to the board. To prevent this, make sure to properly prepare the board before edging.

Conclusion

If you are experiencing problems with edge banding turning white, it is important to troubleshoot the problem to determine the underlying cause. In most cases, the problem is not with the board, but with the edge banding process itself. By following the tips above, you can help to prevent edge banding from turning white and ensure a professional-looking finish.
