Tools for moulding - Shouldered ejector pins
ISO 8694:2011 specifies the dimensions and tolerances, in millimetres, of shouldered ejector pins with cylindrical head which are used in compression and injection moulds and in die casting dies. ISO 8694:2011 also gives material guidelines and hardness requirements, and specifies the designation of shouldered ejector pins.
Outillage de moulage — Éjecteurs épaulés
L'ISO 8694:2011 spécifie les dimensions et les tolérances, en millimètres, des éjecteurs épaulés à tête cylindrique utilisés dans les moulages par compression, les moules d'injection et les moules pour fonderie sous pression. L'ISO 8694:2011 donne également des indications relatives aux matériaux et des exigences relatives à leur dureté, et spécifie la désignation des éjecteurs épaulés.

Overview
ISO 8694:2011 specifies the dimensional, material and marking requirements for shouldered ejector pins with a cylindrical head used in compression and injection moulds and in die-casting dies. This third edition is a minor revision of the 1998 edition and updates surface-texture indications in line with ISO 1302:2002. The standard ensures consistent interchangeability, improved durability and clear designation for tooling components.
Key Topics
- Scope and purpose: Defines dimensions and tolerances in millimetres for shouldered ejector pins used in mould tooling and die casting.
- Dimensions and tolerances: Dimensioning follows the indications given in the standard (see Figure 1 and Table 1). The standard covers key geometric parameters (D, D1, D2, L, H, R) and associated tolerances to ensure proper fit and function.
- Surface finish: Surface roughness recommendations are provided in the figure key. Typical guidance includes Ra 0.8 µm for hot-worked steel and Ra 0.4 µm for alloyed cold-worked steel, with allowances for alternate finishes or small diameter variations over defined lengths.
- Concentricity: A concentricity tolerance of 0.05 mm is specified and measured over a maximum distance of 10 mm immediately after the radius joining the shoulder diameters.
- Materials and hardness: The standard permits either hot-worked steel or alloyed cold-worked steel. Hardness requirements are indicated in the standard, with typical values including a minimum hardness for hot-worked/hot-forged material and specified HRC ranges for different material options. The point of hardness measurement is left to the manufacturer's discretion.
- Designation rules: Clear designation format is specified to standardize ordering and documentation.
Applications
ISO 8694:2011 is primarily used by:
- Toolmakers and mould designers specifying ejector pins for injection, compression and die-casting tooling
- Production engineers ensuring component interchangeability across dies and moulds
- Purchasing and quality teams requiring unambiguous designation and acceptance criteria
Benefits include:
- Interchangeability of ejector pins across compatible tooling
- Improved lifecycle and reliability through specified hardness and surface requirements
- Reduced ambiguity in procurement via a standardized designation format
Related Standards
- ISO 1302:2002 - referenced for surface-texture indication updates
- ISO 6751 - ejector pins with cylindrical head
- ISO 8693 - flat ejector pins
Use ISO 8694:2011 when specifying shouldered ejector pins to align dimensions, surface finish, material and hardness with internationally accepted tooling practice, and to ensure clear, consistent designation in technical documentation and procurement.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International 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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 8694 was prepared by Technical Committee ISO/TC 29, Small tools, Subcommittee SC 8, Tools for
pressing and moulding.
This third edition cancels and replaces the second edition (ISO 8694:1998), of which it constitutes a minor
revision. In particular, the indication of surface textures has been updated in accordance with ISO 1302:2002.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée
aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du
comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI,
Partie 2.
La tâche principale des comités techniques est d'élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur
publication comme Normes internationales requiert l'approbation de 75 % au moins des comités membres
votants.
