Common Problems and Analysis of Furniture Edge Sealing

1. When performing edge trimming procedures, the edges are prone to detachment

The glue coating is too thin;

The material is too cold or damp (especially when just glued);

If the glue line is clearly visible and displays the pattern of the glue roller, it may be because the temperature of the glue roller is too low;

The conveyor belt speed is too slow;

The temperature of the surrounding environment or materials is too low (working below 15 ° C);

Insufficient pressure.

2. The initial position and location of the edge banding are not ideal

The roller pressing wheel needs to master the skills to make adjustments, and extend the position to increase the roller pressure.

The 125px position at the beginning or end of the adhesive surface of the adhesive roller is often not ideal, because the adhesive roller at the head and tail positions is prone to insufficient pressure, and when in high-speed production, the contact between the adhesive roller and the panel is prone to jumping.

3. The effect of bonding both sides is good on one side and not good on the other

Poor contact between the panel (substrate) and the pressure wheel;

Uneven application of glue leads to glue leakage, which hinders the edge sealing process.

4. Intermittent poor adhesion condition

The liquid state of hot melt adhesive is too low in temperature;

When the edge banding machine is tuned too fast and the amount of glue applied is too high, the hot melt cylinder fails to melt the hot melt adhesive in a timely manner, resulting in uneven glue application;

The temperature of the hot melt machine is unstable.

5. The edge is quickly detached after bonding

Hot melt adhesive, sealing edge, substrate, goods or pressure roller temperature is too high;

The temperature of the construction environment (room temperature) is too high;

Excessive glue application;

The humidity of the edge banding or substrate is too high;

The substrate and edge banding themselves contain resin (oil-based) components, which reduce adhesion and often occur in the process of using veneer/solid wood edge banding.

6. There are flower marks on the surface of the edge banding

The edge sealing material is too thin and the surface wear resistance is weak;

The edges of the panel are rough;

The adhesive film lacks elasticity.

7. There is a pen tip shape or protrusion on the surface of the edge banding

Due to contamination by dust particles or wood debris, the hot melt adhesive may become uneven after pressure, so it is necessary to ensure the cleanliness of the hot melt machine.
