In the process of custom metal stampings, the deformed part is rough. When the surface roughness reaches more than ten microns, the paint should be painted 2 or 4 times to cover it. However, the paint surface is not smooth, so it is still difficult to make up for rough surface.
Thus, when the surface roughness, or spray a layer of spray putty, or according to the requirements of the situation, with the removal of the sander.
Measures to prevent this surface roughness are to find the cause, and the most necessary treatment is to reduce the amount of deformation of the rough surface. For example: change the forming conditions; change shape, etc..
We can also supply the deep drawing parts, ODM machining parts etc. If you need, welcome to contact us.
