1 Scope

GB/T 47256-2026 is the Chinese national standard covering the safety of moulding and coremaking machines - the closing and clamping movements that can crush, the core shooters and their gas, the amine catalyst in cold box coremaking and the guarding and interlocks around all of it. It is one of seven foundry machinery safety standards published together on 27 February 2026, which between them cover a whole foundry: melting, moulding and coremaking, pouring, shakeout, blasting, sand plant and die casting. First edition, in force since 1 September 2026. It was issued on 27 February 2026 and has been in force since 1 September 2026, as a first edition. The document is under the responsibility of the China Machinery Industry Federation. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document specifies the safety requirements and/or risk reduction measures and usage information for molding and core-making equipment, and describes the corresponding verification methods. This document outlines the procedures for using molding and core-making equipment for its intended purpose and for use under conditions of misuse that the manufacturer could reasonably foresee. Examples of major hazards, hazardous conditions, or hazardous events related to this type of equipment (see Appendix A). This document applies to the design, manufacture, and acceptance of molding and core-making equipment.

Note. Molding and core-making equipment includes molding machines, molding production lines, core-making machines, core-making production lines, sand core drying equipment, and sand mold drying equipment. This document does not apply to investment and lost foam casting equipment, sand core/sand mold 3D printing equipment, casting equipment, ventilation and dust removal equipment, or exhaust gas systems. Processing equipment.
