Painting process of carbon fiber tube

Painting process of carbon fiber tube

The carbon fiber tubes we see on the market are painted, whether they are matte tubes or bright tubes.
Today we will talk about the painting process of carbon fiber pipes.

After the carbon fiber tube is cured and formed at a high temperature by a hot press or a hot autoclave, the surface of the carbon fiber tube needs to be processed with sandpaper or sanding equipment.
The purpose of this step is to make the surface of the carbon fiber tube flat. After polishing the surface of the carbon fiber tube, there will be a lot of debris attached to the surface.
You can choose to remove the debris on the surface with water or a cleaning agent.
When the surface moisture is completely dry, the walking path of the spray gun can be designed according to the shape of the carbon fiber tube for spraying.
When spraying, pay attention to uniform paint. Generally, carbon fiber tubes need to be sprayed three times: primer, colored paint, and surface clear paint.
Each spray needs to be baked once. During the painting process, it is found that there are paint particles or depressions on the surface of the carbon fiber tube, and it needs to be polished or filled until the surface is smooth, so that the painting step of the carbon fiber tube is completed.
In the process before and after painting, trimming, sandblasting, and polishing are also required.

The labor and time required are relatively large, which directly leads to a relatively long production cycle of carbon fiber tubes and other carbon fiber products.
