AI Technical Summary
Existing wood door pressing devices can only apply stable downward pressure during pressing, resulting in uneven pressure distribution between the MDF and the filling layer. This can easily lead to uneven bonding in certain areas, causing the MDF and filling layer to easily delaminate during later use.
The door panel is pressed more evenly by repeatedly rolling it with pressure rollers. The design of the device is protected by pads and springs to prevent direct contact damage. The detachable pressure rollers and clamps make it easy to replace and adjust the height of the device.
This achieves a more uniform and firm bonding between the MDF and the filling layer, reduces delamination between the MDF and the filling material, increases the sturdiness of the wooden door, improves the uniformity of the bonding between the MDF and the filling layer, and makes the adhesion between the MDF and the filling layer of the MDF door more uniform and firm, thus increasing the door's sturdiness and preventing delamination between the MDF and the filling layer.
