Functional Evaluation of Transformation of a Metal Mold after Heat Treatment by Transferability

Abstract

The functional requirements in the heat treatment of metal molds are conformity of hardness to the target value and minimal distortion after the heat treatment. A manufacturer who outsources heat treatment can reduce post-processing costs and losses to consumers by choosing a heat treatment vendor based on a functional evaluation of its heat treatment technology, In this study, we performed a functional evaluation by using transferability to evaluate surface hardness and distortion after heat treatment, and used a loss function to select a heat treatment vendor.
