Champ d’application

This standard is applicable to various types of molding machines used in foundries for molding, as well as auxiliary machines in molding lines. It specifies the basic safety technical requirements that designers, manufacturers, suppliers, and users must follow. This standard is mandatory for all molding machine manufacturers and suppliers operating in the Chinese market. It does not apply to equipment outside the specified foundry molding machinery categories.

Exigences techniques

The standard outlines comprehensive safety requirements based on risk assessment principles. It mandates that molding machines must achieve intrinsic safety through design, eliminating hazards wherever possible before relying on protective devices or user information. For the worktable-pattern plate area, identified as the primary danger zone, the standard requires secure installation of tooling and the use of safety distances or two-hand control devices. Protective devices must be interlocked with the control system to prevent operation when not in the correct position. Regarding hydraulic and pneumatic systems, the standard specifies requirements for pressure maintenance, leakage prevention, and the safe handling of accumulators. It mandates that hydraulic systems have adequate heat dissipation, with automatic alarms and shutdowns at specific temperature thresholds. Additional requirements cover electrical systems, control systems, noise and vibration reduction, and ergonomic principles. The standard emphasizes the prevention of mechanical, electrical, fluid, and material hazards, ensuring that machines are designed to minimize risks from moving parts, high-pressure fluids, and harmful substances.

Méthodes d’essai

Compliance with the safety requirements is determined through four prioritized methods: functional testing, measurement using instruments, calculation and/or drawing review, and visual observation. Functional testing is the preferred method to verify if components meet specified safety functions. If functional testing is technically infeasible or requires destructive testing, subsequent methods like measurement or calculation are utilized. Each safety requirement must be verified by at least one of these methods.
