Spray Painting Technology of CNC Prototype
Spray painting characteristics:
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
effect 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.
