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 or 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 the ISO 23472 series are foundry machines used in foundry production.
The purpose of the ISO 23472 series is 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 difference between 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:
— molding and coremaking 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 molding and coremaking machines and other
equipment related to non-permanent mold casting process. This includes basic concepts specifically
concerning structural characteristics and functions, important mechanisms and parts, main
technological processes and parameters of various molding machines, coremaking machines, knock-
out equipment, equipment for molding sand preparation and sand reclamation, equipment for lost foam
casting and investment casting, and other related equipment (see Figure 1).

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.

ISO 23472-2:2020(E)
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 or 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 the ISO 23472 series are foundry machines used in foundry production.
The purpose of the ISO 23472 series is 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 difference between 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:
— molding and coremaking 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 molding and coremaking machines and other
equipment related to non-permanent mold casting process. This includes basic concepts specifically
concerning structural characteristics and functions, important mechanisms and parts, main
technological processes and parameters of various molding machines, coremaking machines, knock-
out equipment, equipment for molding sand preparation and sand reclamation, equipment for lost foam
casting and investment casting, and other related equipment (see Figure 1).
