Nowadays, the copper door is no longer an elusive one. Up to now, many ordinary people have installed copper doors in their homes, but copper doors are not like ordinary doors. Copper doors need regular maintenance. Once there are problems with copper doors, we need to deal with them carefully. Take the copper door depression as an example, Now let's follow the copper door manufacturer to understand what to do if the copper door is sunken!

据铜门厂家介绍，铜门凹陷的处理方法一共分为三步，一步：将凹陷修复，也是很难的一步，有三种方法：

According to the introduction of Tongmen manufacturer, the treatment method of Tongmen depression is divided into three steps. One step: repairing the depression is also a difficult step. There are three methods:

1.低压被真空机器的负压吸上来。这个方法只适用于薄金属片的铜门，不适用于厚金属片。

1. The low pressure is sucked up by the negative pressure of the vacuum machine. This method is only applicable to copper doors with thin metal sheets, not thick metal sheets.

2.用高强度磁铁吸上来。由于同一扇门中间是空的，可以用钕铁硼强磁铁放在门的中空部分。外部由弱磁性铁丝引导，使强磁铁到达凹部，然后外部被高强度电磁铁吸引。厚度约1毫米的铜板可以抬起来。如果厚度较大，应该使用第三个方法。

2. Suck it up with a high-strength magnet. Because the middle of the same door is empty, neodymium iron boron strong magnet can be placed in the hollow part of the door. The outside is guided by weak magnetic iron wire to make the strong magnet reach the recess, and then the outside is attracted by high-strength electromagnet. A copper plate with a thickness of about 1 mm can be lifted. If the thickness is large, the third method should be used.

3、在铜门凹陷处焊接多个铜枝作为着力点，用液压或者换轮组进行大力牵引，可将铜板凹陷提起来。

3. Multiple copper branches are welded at the copper door depression as the force point, and the copper plate depression can be lifted by strong traction with hydraulic pressure or wheel change group.

二步：用砂轮将修复后的凹陷磨平。带有弧线或棱角的位置需要与门的整体形象相统一。如果有焊接的铜枝，先打磨掉，再进一步打磨平整。

Step 2: grind the repaired depression with a grinding wheel. The positions with arcs or edges and corners need to be unified with the overall image of the door. If there are welded copper branches, polish them first, and then further polish them flat.

三步：着色：制作铜门时用着色腐蚀液着色，保障整个铜门颜色均匀。

Step 3: coloring: color the copper door with coloring corrosive solution to ensure the uniform color of the whole copper door.

四步：喷漆，使用相同名称或相同颜色的铜门保护漆进行喷漆保护，完成整个铜门凹陷的修复。

Step 4: Painting: use copper door protective paint with the same name or color for painting protection to complete the repair of the whole copper door depression.

沉铜门的修复方法大致可以分为以上四个步骤。遇到这样的问题，可以参考上面的内容修复铜门，相信很好效果。

The repair method of sunk copper door can be roughly divided into the above four steps. In case of such a problem, you can refer to the above content to repair the copper door. I believe it has a good effect.

看完铜门厂家为大家介绍的铜门凹陷的解决方法，你学会了吗?此外，大家在平时一定定期对铜门进行保养维护，这样不仅能提升铜门的效用效果，还能延长铜门的使用寿命，一举两得!

Have you learned how to solve the copper door depression introduced by the copper door manufacturer? In addition, we must regularly maintain the copper door at ordinary times, which can not only improve the effectiveness of the copper door, but also prolong the service life of the copper door, killing two birds with one stone!
