ISO 23472-3:2021

Overview

ISO 23472-3:2021 - Foundry machinery - Vocabulary - Part 3 provides a standardized set of terms and definitions for die casting machines and equipment used in the permanent mold casting process. Published by ISO/TC 306 (Foundry machinery), this vocabulary is intended to remove ambiguity in technical documentation, international exchanges and multilingual communications by defining clear, concise English terminology for die casting, squeeze casting, low‑pressure casting, centrifugal casting, gravity die casting and related equipment.

Key topics

The standard focuses on vocabulary and covers practical technical concepts such as:

• Machine classifications: hot‑chamber and cold‑chamber die casting machines, squeeze casting, low‑pressure and centrifugal casting machines, gravity die casting.
• Structural components and parts: platens (fixed and moving), shot sleeve, plunger, gooseneck, holding furnace, ejection plate/rods, docking devices.
• Functional systems: die closing system, injection system and drive, ejection system, heating/cooling (die temperature controllers), intensification systems.
• Process parameters and actions: injection speed/pressure, fast injection and acceleration, injection follow‑through, die locking/clamping force, dry cycle time, casting volume/area.
• Safety and cell concepts: die casting cell (machine + auxiliary/ancillary equipment), die closing safety devices, access doors and guards.
• Administrative notes: the document contains no normative references and is part of the broader ISO 23472 series; ISO and IEC terminology resources are recommended for cross‑reference.

Applications

ISO 23472-3:2021 is useful wherever precise die casting terminology is required:

• Manufacturers and machine designers - ensure consistent names for components, functions and parameters in specifications and drawings.
• Foundry engineers and process specialists - standardize process descriptions, performance metrics and machine selection criteria.
• Technical writers, translators and documentation teams - produce unambiguous manuals, maintenance guides and safety documentation.
• Procurement and quality - define contractual requirements, acceptance criteria and equipment lists.
• Training and R&D - create curricula and publications with globally recognized terminology.
