Abstract text

A spray coating apparatus in which gas turbulence is reduced to provide a better controlled spray coating process. The spray coating apparatus comprises a coating chamber, a spray nozzle, and an article holder for holding the article to be coated. Waste gaseous materials generated during the spray coating are extracted through an extraction port on the coating chamber. The amount of extraneous gas flow entering the coating chamber is limited to reduce the amount of gas turbulence in the coating chamber. Also disclosed is a method of spray coating with reduced gas turbulence.
