Toyota developed a new painting process; it’s the first of its kind in the world for automotive use, and has the highest coating efficiency in the world. Typically paint is applied with air paint atomizers, which use air pressure, but plenty of paint ricochets off the surface and is wasted. The new process uses a spinning cylindrical head combined with centrifugal force to sling out. electrostatically charged paint droplets. The droplets are attracted to the grounded surface of the vehicle where the paint can attach and the static charge can be dissipated. This process achieves over 95% coating efficiency, versus just 60-70% coating efficiency from conventional car painting methods.
