1 Scope

China's national standard for the classification and model designation of foundry machinery, and the current edition of GB/T 31552, replacing the 2015 edition. It specifies the classification of foundry machinery and the method by which a model designation is built, with a normative annex giving, for every class of equipment, the type and group divisions, the type codes and the main parameter codes. It is a large document - the annex alone occupies thirty pages of tables - because foundry machinery is not one kind of machine but ten. The classification divides it into sand preparation and sand reclamation equipment, moulding and core making equipment, shakeout and core removal equipment, cleaning equipment, permanent and semi-permanent mould casting equipment, investment and lost foam casting equipment, melting and pouring equipment, transport and metering equipment, inspection and control equipment, and others, each with its own class letter and its own table of groups, types and parameter codes. A designation built on that scheme tells a reader what the machine is, what group it belongs to, its principal size or capacity and its variant, in a few characters - which is what makes a foundry's equipment register, a spare parts catalogue and a purchase order intelligible across manufacturers. The 2023 revision restates the scope, adds an explicit classification method with its basis and a classification diagram, and renames four classes: sand processing becomes sand preparation and sand reclamation, shakeout becomes shakeout and core removal, metal mould equipment becomes permanent and semi-permanent mould casting equipment, and investment moulding becomes investment and lost foam casting equipment. It also adds and merges groups and moves several between classes. Issued on 17 March 2023 and in force since 1 October 2023.

This document specifies the classification and model compilation methods of foundry machinery: This document applies to the design, manufacture and trade of foundry machinery:
