This experiment used simulations to explore possible conditions by which molded products similar to the mold shape could be obtained. The experiment succeeded in finding conditions by which similarity between mold shape and molded product shape can be increased and demonstrated the possibility of reducing the number of mold prototypes, together with the further possibility of proto-type-less injection molding. The shrinkage ratio tendencies at different points in the molded products were also clarified.
