How to Perfectly Fix Veneer Edge Banding Bubble245

Veneer edge banding bubble refers to the phenomenon of local bulging or detachment of the veneer after the edge banding machine is used for edge sealing. The bubble usually occurs at the corner or end of the veneer. It not only affects the appearance of the furniture, but also reduces the service life of the veneer edge banding. If the bubble is not handled properly, it will easily lead to the cracking and peeling of the veneer, which will seriously affect the quality of the furniture.

There are many reasons for the bubbling of veneer edge banding. Some common reasons include:
The temperature of the hot melt adhesive is too high, which causes the adhesive to penetrate into the veneer and weaken the bonding strength.
The pressure of the edge banding machine is too low, which fails to fully bond the veneer to the substrate.
The veneer is not dry enough, which contains too much moisture and causes the veneer to swell and bubble after bonding.
The substrate is not flat, which causes uneven bonding of the veneer and results in bubbles.
The veneer is not properly trimmed, which leaves gaps between the veneer and the substrate, allowing air to enter and form bubbles.

To avoid the bubbling of veneer edge banding, the following measures should be taken:
Choose the appropriate hot melt adhesive according to the veneer material and thickness.
Control the temperature of the hot melt adhesive within the appropriate range. Generally, the temperature should be between 160-180 degrees Celsius.
Adjust the pressure of the edge banding machine to ensure that the veneer is fully bonded to the substrate.
Dry the veneer before edge banding to reduce the moisture content.
Ensure that the substrate is flat and free of defects.
Trim the veneer properly to eliminate gaps and prevent air from entering.

If veneer edge banding bubbles occur, the following methods can be used to repair them:
Use a sharp knife to carefully cut the bubbled area.
Apply a small amount of hot melt adhesive to the cut area.
Press the veneer back into place and apply pressure until the adhesive has cooled and set.
Use a sanding block to smooth out the repaired area.

By following these steps, you can effectively repair veneer edge banding bubbles and ensure the quality and appearance of your furniture.
