Postprocessing-Polishing and Its Function
When polished, prototype has distinctions on shape and structure.
If the shape is not special,there is no much difference to finished-product
when polished. We should choose different abrasive paper. At first we can
choose some rather rough abrasive paper to polished rough selvage and then
process with more detailed polishing. According to different requirement of
surface, the level of polishing would be different. After polishing,
prototype should be sprayed some putty to make the roughness of surface
more obvious and check the problem existed. So at this time, when amended,
it would be targeted until all polishing have finished.
The three functions of polishing processing
First, strengthening the adhesive force of painting. Before paint new film,
the old film should be polished. So after polished, the adhesive force of
prototype will be strengthened.
and dust on surface.
Third, smoothness. The surface raw material is rough generally.
So polishing can reduce the roughness of surface.
