Title:
MOLD MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/160095
Kind Code:
A1
Abstract:
Provided is a method for manufacturing a mold which is to be used for molding a resin through an imprinting method and which enables formation of a highly-precise molded body through compensation for contraction deformation associated with hardening or solidification of the resin. This method is for manufacturing a mold for manufacturing, through molding of a resin, molded bodies having a variety of aspect ratios and having conical shapes, pyramid shapes, frustum shapes, circular cylindrical shapes, prismatic shapes, imperfect spherical shapes, or linear shapes having a rectangular, trapezoidal, triangular, or imperfect spherical cross-section in a plane perpendicular to the longitudinal direction. The method is characterized by determining a prediction function regarding deformation that occur when a resin having an arbitrarily-defined rate of dimensional change is molded into a molded body having an arbitrarily-defined aspect ratio, calculating a correction function for compensating deformation from the prediction function, and designing a mold using the correction function.
