MOLDING OF DUPLICATED PRODUCT

摘要

PROBLEM TO BE SOLVED: To mold a duplicated product within a short time by simple operation by irradiating an internal photo-setting liquid resin with light through the wall part with a thickness of several-several hundred mm of a templating matrix obtained by curing a photo-setting liquid silicone rubber compsn. from the outside. SOLUTION: The cavity of a matrix having the cavity corresponding to the outer shape of a product to be duplicated is filled with a liquid resin and this liquid resin is cured to mold a duplicated product. In this method, the matrix is formed from transparent cured matter of a photo-setting liquid silicone rubber compsn. and the cavity of this matrix is filled with the photo-setting liquid resin and irradiated with light from the outside of the matrix by using an ultraviolet fluorescent lamp 8 to cure the photo-setting liquid resin in the matrix.
