Nowadays, the copper door is no longer the one that could not be expected at the beginning. Up to now, many ordinary people have installed copper doors in their homes, but copper doors are not the same as ordinary doors.

铜门需要我们平时定期的去维护保养，而铜门一旦出现问题，需要我们小心翼翼的去处理，就拿铜门凹陷来说吧，下面我们跟随济南铜门厂家一起来了解一下铜门凹陷了怎么办!

Copper doors need our regular maintenance, and once there is a problem with copper doors, we need to handle it carefully. Let's take the copper door sag as an example. Let's follow Jinan copper door manufacturers to understand what to do with the copper door sag!

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 copper door manufacturers, the treatment of copper door depression is divided into three steps. One step is to repair the depression, which is also a very 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 suitable for thin sheet metal doors, not for thick sheet metal doors.

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. Draw it up with a high-strength magnet. As the middle of the same door is empty, a strong NdFeB magnet can be placed in the hollow part of the door. The outer part is guided by weak magnetic wire to make the strong magnet reach the concave part, and then the outer part is attracted by high-strength electromagnet. A copper plate about 1 mm thick can be lifted up. If the thickness is large, a 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. Several copper branches are welded at the copper door depression as the force point, and the copper plate depression can be lifted by hydraulic or wheel changing group for strong traction.

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: use grinding wheel to smooth the repaired depression. The position with arc or corner needs to be unified with the overall image of the door. If there is any welding copper branch, it shall be polished off first, and then further polished and leveled.

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。

Three steps: coloring: when making the copper door, use the coloring corrosive solution to make the color of the whole copper door uniform.

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。

Four steps: painting, using the same name or the same color of copper door protective paint for painting protection, 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。
