Department of Production Engineering, Faculty of Engineering, King Mongkut’s University of Technology Thonburi (KMUTT), Bangkok, 10140, Thailand
This research aims at studying the relationship of factors used in the process of spray coating in cookware industry. This research is divided into two parts. One is studied using an experimental design process, and the other is the geometric modeling for the process of exterior spray coating. This experiment is conducted to determine the appropriate parameters with an aim to use the least amount of coating material and the standard dry film thickness. The important factors of study are consisted of the height of spray gun, angle, spray pressure, spray time, and nozzle size. From the analysis of the experiment, it can be concluded that 23 cm of height, 95 degrees of gun angle, 5.4 bar of air pressure 1.95 seconds of spray time, 295 degrees of nozzle size is proposed. As a result, it can decrease the consumption around 2.82 g per piece.
