As the new model development lead time becoming shorter and the market requirements becoming more strict, automobile manufacturer begins to utilize 3-dimensional CAD system based techniques such as DMU (Digital Mock-up), Rf (Rapid Prototyping), VE (Virtual Engineering) to meet the market trends. But, no satisfactory utilities have been developed yet, to represent emotional properties such as embossment on the surface of interior parts, touch originated from material characteristics in virtual environment, so it is inevitable to manufacture prototype parts to verify actual feeling which passengers feel in automobile. This paper suggests a methodology to enhance the human sensitivity via embodying embossment on the surface of prototype car interior trim without deterioration of dimensional accuracy using RIM (Reaction Injection Molding) and thermoforming method.

To reduce the leadtime for a new model according to the strict market requirements, automobile manufacturer begins to utilize 3-dimensional CAD based techniques such as DMU(Digital Mock-Up). RP(Rapid Prototyping), VE(Virtual Engineering). But, not so many satisfactory utilities have been introduced to deal with the emotional properties such as embossment on the surface of interior parts and touch from material characteristics in virtual environment. It is required to manufacture prototype parts to verify actual feeling of the passengers in real automobile. This paper suggests a methodology to enhance emotional property via embedding embossment on the surface of prototype car interior trim without deterioration of dimensional accuracy using RIM(Reaction Injection Molding) and vacuum forming method.
