Overview
ISO 8693:2011 - Tools for moulding - Flat ejector pins describes standardized dimensions, tolerances, materials and hardness for flat ejector pins used in compression and injection moulds and in die-casting dies. The third edition (2011) updates surface texture indication in line with ISO 1302:2002 and defines how to designate flat ejector pins for procurement and documentation.
Key topics and requirements
- Dimensions and tolerances (mm): Dimensional tables and Figure 1 specify widths, thicknesses, lengths and gauge planes for flat ejector pins. Tables cover both hot-worked and alloyed cold-worked steel variants.
- Surface finish: Surface roughness values are given (e.g., Ra values differentiated for hot-worked and alloyed cold-worked steel). Edges must be without burrs; gauge planes are defined for measurement.
- Material guidance: Pins shall be made from hot-worked steel or alloyed cold-worked steel. The standard provides mechanical property guidance (including core strength and hardness ranges) and leaves the exact measurement point to the manufacturer’s discretion.
- Hardness requirements: The standard specifies hardness targets for shaft and head (table values include HV and HRC ranges for the two material families).
- Designation format: Prescribes a clear designation:
Flat ejector pin ISO 8693 - a × b - L - Material
Example: Flat ejector pin ISO 8693 - 0.8 × 3.5 - 63 - Hot worked steel. - Length correction: For lengths greater than the reference (100 mm), the document provides a method to scale limit deviations - see the tables for the specific factor.
Practical applications
- Ensures interchangeability and quality control of flat ejector pins in:
- Injection mould tooling
- Compression moulds
- Die-casting dies
- Helps toolmakers, mould designers and component manufacturers specify pins that meet consistent dimensional and hardness criteria, reducing trial-and-error during assembly and improving mold lifetime and part ejection reliability.
- Useful for procurement and quality inspection teams to verify conformity against a recognized international standard.
Who should use this standard
- Tool and die makers, mould designers and maintenance engineers
- Manufacturing and quality managers in plastics and die-casting industries
- Purchasing specialists and technical document authors preparing part specifications

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 8693 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 8693:1998), 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.
L'attention est appelée sur le fait que certains des éléments du présent document peuvent faire l'objet de
droits de propriété intellectuelle ou de droits analogues. L'ISO ne saurait être tenue pour responsable de ne
pas avoir identifié de tels droits de propriété et averti de leur existence.
L'ISO 8693 a été élaborée par le comité technique ISO/TC 29, Petit outillage, sous-comité SC 8, Outillage de
presse et de moulage.
Cette troisième édition annule et remplace la deuxième édition (ISO 8693:1998), dont elle constitue une
révision mineure. En particulier, l'indication des états de surface a fait l'objet d'une mise à jour selon
l'ISO 1302:2002.
