The influence of electrostatic point application process variables on the orange-peel effect or: A case study in the use of experimental design methods

The surface appearance of a motor vehicle is an important property to a pot ential customer. Gloss has been measured for many years, but new measuremen t instruments enable the orange-peel effect to be quantified. This enables statistical experimental design techniques to he used to reduce to orange p eeling. This paper describes the authors' experience of the use of experimental des ign techniques to investigate the influence of process variables of electro static spinning bells on the final point finish.
