Die and mold technology

 UTSUNOMIYA Takao
Course description
Industrial products are produced by various production and processing technologies. Die & mold technology is one of the major production and processing technologies. In this lecture, the production and processing technologies including die & mold technology are explained. In addition, from the viewpoint of safe and secure manufacturing, the functional evaluation and design methods for manufacturing are studied for basic mechanical elements. Each class will consist of a lecture and exercises, and the achievement of the objectives will be evaluated by examinations based on the exercises.
Purpose of class
The aim of this course is to understand safe (damage-free) design methods based on an understanding of the basic properties of materials and the functions of machine elements, in addition to an overview of production and processing technologies including mold technology.
Goals and objectives
  1. To understand and explain overviews for die & mold technology and, production and processing technologies of machine elements.
  2. To understand and explain material properties and failure criterion.
  3. To evaluate the functions and specifications of machine elements and perform practical safety design taking them into account.
