1. The laminating paper used to press the surface of the selected board should be used at high temperature. At high temperature, the flatness of plate surface is the worst and it is easy to deform. Under normal circumstances, it is stacked in the open air for heat dissipation: summer 10- 15 days, and winter 5-7 days.

2. The size problem of the functional board is reflected in the deformation of the board.

3. The performance of this board is very poor

The reasons for the above deformation, answering customers needs skills.

1, the two ends of the arch are downward and the middle is upward. As long as it is not more than 3-5mm, it will naturally be downward when storing objects.

2. If the deformation is serious, you need to compensate the customer.
