Abstract
A system and method for spray application of polyurethane used to spray form an article is disclosed. A spray nozzle is rotated as the polyurethane composition is sprayed onto a mold surface to apply a swath of polyurethane to the mold surface. The spray nozzle may be of an internal mixing or external mixing type that is moved relative to a mold surface in a path to create a skin layer with multiple partially overlapping swaths being applied in multiple passes. A motor and gear drive are used to rotate the nozzle tip and associated structure.
