TABLE OF CONTENTS Dies can be classified according to a variety of elements and in keeping with the diversity of die designs. In this section, we will discuss primarily die classifications depending on the production quantities of stamping pieces (whether high, medium, or low) and the number of stations. In choosing these, we are not trying to downplay or ignore other classifications such as the number of operations, manufacturing processes, or guide methods.
Depending on the production quality of pieces high, medium, or low stamping dies can be classified as follows:
Class A. These dies are used for high production only. The best of materials are used. All easily worn items or delicate sections are carefully designed for easy replacement. A combination of long die life, constant accuracy throughout the die life, and ease in maintenance are prime considerations, regardless of tool cost.
Class B. These dies are applicable to medium production quantities and are designed to produce the designated quantity only. Die cost as related to total production becomes an important consideration. Cheaper materials may be used, provided they are capable of producing the full quantity. Less consideration is given to the problem of ease of maintenance.
Class C. These dies represent the cheapest usable tools that can be built. They are suitable for low-volume production of parts.
According to the number of stations, stamping dies may be classified...
