Edge Banding Trimming: Causes and Solutions for White Lines66

As a leading Chinese edge banding strip manufacturer, we are frequently approached by customers seeking solutions for the problem of white lines appearing on trimmed edge banding. This issue can be particularly frustrating, especially for furniture manufacturers aiming for high-quality aesthetics and finishes on their products.

White lines on edge banding strips after trimming can be caused by several factors, but the most common is the presence of excess glue residue. When the edge banding is applied to the substrate, it is essential to ensure that the glue is evenly distributed and that any excess is removed immediately. Failure to do so can result in the formation of white lines when the edge band is trimmed.

Another potential cause of white lines is the use of blunt or dull trimming tools. When the blades are not sufficiently sharp, they can "tear" the edge banding material, leaving behind a white or discolored surface. To prevent this issue, it is crucial to use sharp, high-quality trimming tools and to replace them regularly as they become dull.

In addition to glue residue and dull tools, white lines on edge banding can also be caused by excessive heat buildup during the trimming process. This can occur when the trimming speed is too high or if the trimming tool is not cooled properly. To mitigate this issue, it is essential to use a proper cooling system and to adjust the trimming speed to an optimal level.

Once you have identified the cause of the white lines on your edge banding strips, you can take steps to rectify the problem. For glue residue issues, ensure that excess glue is removed promptly and thoroughly during the edge banding application process. For trimming blade-related issues, invest in sharp, high-quality tools and replace them regularly. If heat buildup is a concern, adjust the trimming speed and implement a proper cooling system.

In summary, the appearance of white lines on trimmed edge banding strips can be attributed to excess glue residue, blunt trimming tools, or excessive heat buildup. By addressing these issues through proper glue application, using sharp blades, and optimizing the trimming process, you can effectively prevent this problem and achieve high-quality results in your furniture production.
