How to repair the depression of the copper door of the villa? First of all, we need to see whether the area of the depression is large, because among all the daily maintenance of the copper door, the phenomenon of depression is the most troublesome, but for the copper door manufacturer, these are not problems. Today, the editor will share with all readers the methods and steps on how to repair the dent in the copper door.

The first step is to repair the dent, which is also the most difficult step. There are three methods:

1. Use a vacuum machine to evacuate with negative pressure. This method is only applicable to thin-plate copper doors. Not applicable if sheet metal is thicker.

2. Fix with high-strength magnets. Because the middle of the same door is empty, you can use a strong NdFeB magnet to place it in the hollow part of the door. The outer part is guided by the weak magnetic wire, so that the strong magnet reaches the concave part, and then the outer part is attracted by the high strength electromagnet. It is possible to lift up about 1mm thick copper recesses. If the thickness is larger, a third method is required.

3. Weld a number of copper branch pipes in the depression of the copper door as stress points. Copper plate dents can be eliminated with hydraulic traction or strong wheelset traction.

The second step is to sand the repaired dent with the same grinding wheel. The location of the arc or corner must match the overall image of the door. If there is a welded copper branch pipe, the copper branch pipe should be ground first, and then ground.

The third step is to color the copper door with a colored corrosive solution to ensure that the entire copper door has a uniform color.

The fourth step is painting. The spray protective paint should be the copper door protective paint of the same name or color. So far, the repair work of the entire copper door depression has been completed.

Therefore, in the maintenance of copper doors, there are specialized after-sales service personnel for professional docking, so as to achieve perfect results.
