Frankfurt, Germany - A new technology for making polyurethane steering wheels is among the innovations Delphi Corp. will showcase at the 2007 international automotive show (IAA) in Frankfurt, 13-23 Sept. This new process for steering wheel production is "environmentally friendly" claims Delphi, which also says the process allows it to build the tooling 50 percent faster and reduce overall cost by 50 percent.Its good environmental credentials arise since it uses "non-ozone depleting polyurethane foam that aligns perfectly with energy-saving efforts, claims Delphi. Tooling polyurethane to achieve a textured effect is a very critical manufacturing process, according to the supplier. The polyurethane foam-tool-process, used by Delphi to make steering wheels for a new car model launched this year, uses what the company calls "a unique three-dimensional computer modelling process." This applies graining into the tool surface, eliminating the need for master tools, Delphi said. "
