There is a crack in the veneer. Do you know that it is a problem?

The solid wood composite door is made of natural veneer, which is actually made of solid wood skin attached to the MDF. The machine cannot be operated because the surface of the furniture is uneven and the shape is different. Therefore, it is possible to solve the problem that the machine can't do complex modeling by artificially applying veneer.

However, in the process of skinning, we often encounter a problem: that is, the hand-applied veneer is easy to foam, and after the foaming, the veneer is cracked after ironing the veneer surface. This problem has been plaguing many front-line workers. So how do you stick the solid wood without blistering and cracking?

1. The bottom of the substrate is not flat

That is, the MDF substrate is not ground and the surface is not flat.

2. The veneer used is too thick

The veneer used was too thick and the veneer was not wet. Generally, the thickness of the hand-applied veneer is below 0.3mm, which is too thick to be hand-applied, and is prone to problems.

3. The temperature of the iron is not well controlled.

Generally, when the temperature is too low, it is easy to foam and cracks during ironing. In addition to the above problems, it is also related to the ironing temperature is too high, the number of ironing times is too frequent, and the interval time is too short.

4. Glue problem

The use of substandard glue results in insufficient glue or uneven glue. Therefore, choosing high-quality glue is the key to sticking veneer.

Things to be aware of to prevent skin blistering and cracking:

1. The substrate is processed smoothly. It is important to choose a flat surface without deformation.

2, hand-applied veneer should be 0.2 mm, try not to exceed 0.25 mm.

3, the iron temperature should not be too low. Of course, it should not be too high and the temperature should be appropriate.

4, the viscosity of the glue should be appropriate, the solid content can not be too low. Glue should be even, pay attention to the quality of the glue.

5, the veneer should be soaked, and then dry to dry humidity suitable for use, but the veneer can not be too wet.

6, the end face or curved face should be divided into multiple times ironing and pay attention to the interval time.

7, the end of the veneer should not be cut off with a blade, it should be ground with a wooden board pad.
