Abstract
In cookware manufacturing industry, spray coating process plays an important role both in function and appearance quality of a product. Typically, Teflon (PTFE) is used for interior coating to increase corrosive and nonstick. Practically, nozzle size and spray time are crucial variables to dry file thickness (DFT) in the process. In mass production, a product is mounted on a rotating spindle which installed on the conveyor and moves pass the spray guns. Thus, the rotating speed is also a potential variable to the DFT. Thus, the objective of this paper is to explore a relationship of these abovementioned three variables i.e. nozzle size, spray time, and rotational speed to dry film thickness After that the optimal condition such that the required DFT is met will be determined. To achieve this goal, the experimental design technique including analysis of variance (ANOVA) is employed in this study. It is found that each of the three variables affects the DFT. The higher of spray time, nozzle size, and rotational speed, the more coating thickness onto the part. ฉ 2016 Trans Tech Publications.
