How to Avoid Overhang and White Lines When Applying Edge Banding with an Edge Bander174

As a leading manufacturer of edge banding strips in China, we frequently encounter inquiries regarding overhang and white lines that appear when applying edge banding to substrates using an edge bander. These imperfections can compromise the aesthetics and durability of the finished product, and in this article, we aim to provide comprehensive insights into the causes and solutions for these issues.

Causes of Edge Banding Overhang:
Excessive Glue Application: Applying too much glue can cause the edge banding to expand, resulting in overhang at the edges.
Improper Adhesive Selection: Certain adhesives may not be suitable for the specific type of edge banding or substrate, leading to insufficient bonding and overhang.
Incorrect Cutter Position: If the cutter is not positioned correctly, it may fail to trim the excess edge banding, causing overhang.
Faulty Edge Bander: Malfunctioning edge banders, worn-out parts, or improper calibration can contribute to edge banding overhang.

Causes of White Lines in Edge Banding:
Dirty Substrate Surface: Dirt, dust, or oil on the substrate surface can prevent the edge banding from adhering properly, resulting in white lines.
Insufficient Adhesive Pressure: Inadequate pressure applied during the edge banding process can lead to poor adhesion and gaps between the edge banding and substrate, causing white lines.
Incorrect Adhesive Temperature: The adhesive must be heated to the appropriate temperature to ensure proper flow and bonding; incorrect temperatures can lead to white lines.
Excessive Trimming: Over-trimming the edge banding after application can expose the substrate and create white lines.

Solutions to Edge Banding Overhang:
Control Glue Application: Use a calibrated glue spreader to apply the adhesive evenly and in the correct amount.
Select Suitable Adhesive: Choose an adhesive specifically designed for the type of edge banding and substrate being used.
Adjust Cutter Position: Ensure the cutter is positioned correctly to trim the excess edge banding without leaving overhang.
Maintain Edge Bander: Regularly inspect and maintain the edge bander to ensure optimal functioning.

Solutions to White Lines in Edge Banding:
Clean Substrate Surface: Thoroughly clean the substrate surface before applying the edge banding.
Apply Adequate Pressure: Use sufficient pressure during the edge banding process to ensure proper bonding.
Control Adhesive Temperature: Heat the adhesive to the recommended temperature according to the manufacturer's instructions.
Trim Edge Banding Carefully: Trim the edge banding only enough to remove excess material without cutting into the substrate.

By understanding the causes and implementing the solutions outlined above, you can effectively prevent edge banding overhang and white lines when using an edge bander. This will ensure the production of high-quality furniture with aesthetically pleasing and durable edges.
