Spray Painting Technology of CNC Prototype
Currently, air spraying is comparatively extensive spraying
technology in painting craft project. Air spraying makes use
of compressed air which form negative pressure when flow
spray gun. The paint vehicle is absorbed form sucker by
negative pressure, and is sprayed out by spray gun as
painting mists. When painting, painting mists become even
film on the surface of prototype. Air spraying can paint even
film, and smear layers are very smooth. It can spray the hidden
parts such as gaps and unevenness. The utilization rate of
dope is low in this way, which is about 50 to 60 percent.
There are some effects after painting on plastic prototype.
1. Spray painting can cover the deficiency of prototype surface.
2.The plastic itself is difficult to color. Spray painting can paint
many kinds of color on plastic.
3.Spray painting improves the electrostatic properties of plastic,
which can reduce dusty-adsorption.
4.Spray painting strengthens hardness and mar-resistance
of plastic.
5.Spray painting improves weather resistance of plastic.
6.Spray painting can adjust the gloss of plastic surface.
7.Some special lacker such as sand paint, fluff paint can
achieve effect of good appearance and hand feeling.
