Corner Cutting Techniques
When edge banding meets the board material, corner treatment is often required. In such cases, you can use a handheld power tool to bevel the edge banding at a 45-degree angle. This method allows the two strips of edge banding to fit together at a 45-degree joint, resulting in a more aesthetically pleasing finish. Note that before cutting, you must accurately measure the corner angle and length, and mark the cut line on the edge banding.
Corner Heat Forming
If your edge banding material is relatively rigid-making corner treatment via cutting impractical-you may consider using a heat-forming method instead. First, use a heat press to heat the edge banding at the corner point to a specific temperature. Then, press the banding into the desired corner shape and allow it to rest until it cools down and naturally hardens. This method helps prevent the edge banding from fracturing or leaving behind visible cut marks.
Corner Edge Banding
Another common method for treating corners involves applying the edge banding directly around the corner. This technique is suitable for thinner edge banding materials; the banding can be bent to match the contour of the corner and then secured in place using adhesive. When using this method, particular attention must be paid to the degree of curvature at the corner; if the bend is too acute, it may cause the edge banding to deform or crack.
Corner Interlocking
Finally, you may also consider using an interlocking method for corner treatment. This technique is ideal for situations where two strips of edge banding-potentially of different colors or materials-need to be joined together. You can begin by beveling both strips of edge banding at the corner to a 45-degree angle. Next, cut a recess or groove into the inner face of one strip, and then insert the other strip into this groove, securing the joint with adhesive.
