摘要：
In at least one embodiment, the present invention relates to a method and system for making a composite polyurethane skin. In at least one embodiment, the method comprises providing a source of liquid polyol, providing a source of liquid isocyanate, providing a source of liquid low density foaming agent comprising blowing agent and low fogging surfactant, providing a spray mold tool having a mold surface, and providing a spraying device for spraying liquid material at the spray mold tool. The method further comprises, in at least one embodiment, directing polyol and isocyanate to the spraying device to form a polyurethane composition, spraying the polyurethane composition towards the spray mold tool to form a polyurethane skin layer on the spray mold tool, directing polyol, isocyanate and low density foaming agent to the spraying device to form an expandable polyurethane composition, and spraying the expandable polyurethane composition onto the skin layer to form a resilient expandable polyurethane layer on the skin.
