Method of solving a process function for manufacturing an extrusion die

摘要

Methods are provided for solving a process function for modification of a non-test die for use in extrusion of a honeycomb body. The process function is solved by comparing measured widths of a plurality of slots between pins of a test die in the post-removal state and measured widths of a plurality of slots between pins of the test die in the pre-removal state. Methods are also provided for modifying a non-test die for use in extrusion of a honeycomb body. Such methods remove non-test-die material from a plurality of pins of the non-test die based on application of the process function.
