Title:
MOLD PRODUCTION METHOD, AND MOLDED ARTICLE PRODUCTION METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/160166
Kind Code:
A1
Abstract:
Provided is a mold production method whereby it is possible to mold a UV-curable composition with excellent accuracy by means of photoimprinting. This mold production method is a production method for a mold comprising an elastic body and used in molding a UV-curable composition, and is characterized in that deformation accompanying curing of the UV-curable composition is simulated using finite element analysis taking into consideration curing shrinkage [1] of the UV-curable composition and deformation [2] of the mold accompanying the shrinkage, and the mold is designed on the basis of the simulation results.
