Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Introduction
Documentation gives rise to numerous international exchanges of both intellectual and material
nature. These exchanges often become difficult, either because of the great variety of terms used in
various fields or languages to express the same concept, or because of the absence of, or the imprecision
of, useful concepts.To avoid misunderstandings due to this situation and to facilitate such exchanges, it is advisable to
select terms to be used in various languages or in various countries to express the same concept, and
to establish definitions providing satisfactory equivalents for the various terms in different languages.
The objects involved in theISO 23472 seriesare foundry machines used in foundry production.
The purpose of theISO 23472 seriesis to provide definitions in English that are rigorous, uncomplicated
and which can be understood by all concerned. The scope of each concept defined has been chosen to
provide a definition that is suitable for general application within foundry machinery, which includes
machines and equipment adapted in each stage of the processes within different casting processes.
As a metal thermoforming method that fills molten metal into the mold to produce machine parts or
rough parts after solidification, casting has a long history and various processes, and its technology
remains constantly developing and changing. According to the differences in the mold used, or different
ways of molten metal filling or solidification, casting processes are usually divided into sand casting,
permanent casting and other casting processes. According to different casting processes and different
stages of production, casting equipment covered by foundry machinery is divided into the following
major categories:— moldingandcoremaking machines and other equipment related to non-permanent mold casting
process;— die casting machines and other equipment related to permanent mold casting process;
— abrasive blasting machines and other equipment related to cleaning and finishing for casting;
— cupola furnaces and pouring devices and ladles.This document only involves terms and definitions of die casting machines and other equipment
related to permanent mold casting process, including basic concepts specifically concerning structural
characteristics and functions, important mechanisms & parts, main technological processes &
parameters of various die casting machines, squeeze casting machines, low pressure casting machines,
centrifugal casting machines, gravity die casting machines and other related casting machines(see
Figure 1).© ISO 2020 – All rights reserved v
