Full title and description

Tools for moulding — Ejector sleeves with cylindrical head — Basic series for general purposes (ISO 8405:2023). This international standard specifies the dimensional series, tolerances, material guidance, hardness requirements and designation system for ejector sleeves with a cylindrical head used in compression and injection moulds and in die‑casting dies.

Abstract

ISO 8405:2023 defines the basic series of ejector sleeves with cylindrical head: dimensional tables and tolerances (millimetres), recommended materials and heat‑treatment / hardness ranges, and the standardised designation format. It is intended to ensure interchangeability, clear procurement specification and consistent performance of ejector sleeves used in moulding and diecasting tool assemblies.

Scope

This document specifies the dimensions and tolerances, in millimetres, of ejector sleeves with cylindrical head which are used in compression and injection moulds and in die‑casting dies. It also provides material guidelines and hardness requirements and gives rules for the designation of ejector sleeves with cylindrical head. The standard is intended for general‑purpose ejector sleeves forming the basic series used in tool manufacture and maintenance.

Key topics and requirements

• Standardised dimensional tables for ejector sleeves with cylindrical head (diameters, lengths, head dimensions).
• Tolerances and limit deviations given in millimetres for the basic series sizes.
• Material guidance (recommended steels / families) and surface/heat‑treatment considerations.
• Hardness ranges and related requirements to ensure wear resistance and functional lifetime.
• Designation rules and example formats to ensure unambiguous ordering and documentation.
• Application context restricted to compression and injection moulds and diecasting dies (general‑purpose series).

Typical use and users

Used by tool and die makers, mould designers, mould‑component manufacturers, procurement and quality engineers in plastics injection moulding and diecasting industries, and by maintenance teams for specifying and replacing ejector sleeves. Also used by suppliers of standard mould components and by standards/engineering departments to ensure interchangeability and correct material/hardness selection.

Related standards

Previous editions of this standard (for historic reference) include ISO 8405:2020 and earlier versions. Complementary ISO standards for moulding components include standards for ejector pins and related elements (for example standards covering ejector pins with cylindrical head, flat ejector pins and shouldered ejector pins), and national standards that harmonise with these ISO specifications. ISO/TC 29/SC 8 is the technical committee responsible for these tool‑for‑moulding series.
