Full title and description

ISO 10072:2004 — Tools for moulding — Sprue bushes — Dimensions. This International Standard specifies the principal dimensions, tolerances, hardness and designation of sprue bushes (sprue bushings) used principally in injection moulds for plastics and rubber.

Abstract

ISO 10072:2004 defines the main dimensions and tolerances, given in millimetres, for sprue bushes used in moulding tools, and specifies the material/hardness requirements and the standard method of designation for compliant sprue bushes. The document is a short technical specification intended to ensure interchangeability and repeatable manufacturing/inspection of sprue bushes.

Scope

ISO 10072:2004 applies to sprue bushes used mainly in injection moulding and diecasting-type tooling for plastics and rubber. It specifies the principal external and internal dimensions, associated tolerances (in millimetres), the recommended hardness and the standard designation system for sprue bushes. The standard is intended to promote dimensional interchangeability and consistent specification of sprue bushes (including the common forms for machine nozzles and plain nozzles).

Key topics and requirements

• Standardized main dimensions (internal bore, external diameters, lengths) for sprue bushes, given in millimetres.
• Specified dimensional tolerances to ensure fit and interchangeability.
• Material and hardness guidance (recommended hardness range/) for functional wear resistance and service life.
• Designation and marking rules so that individual sprue bushes can be ordered and identified unambiguously.
• Recognition of common forms (for example: form with radius for machine nozzle, and straight form for machine nozzle) as used in national adoptions.

Typical use and users

Users include mould designers, toolmakers, precision machining shops, procurement specialists for mould components, and quality/inspection engineers in plastics and rubber moulding operations. The standard is used when specifying or ordering sprue bushes, when designing gating systems for moulds, and for establishing inspection criteria in production tooling.

Related standards

ISO 10072:2004 replaces and revises ISO 10072:1993 (the 1993 edition was withdrawn and superseded by the 2004 edition). Several national bodies have adopted ISO 10072:2004 as a national standard (for example the DIN adoption as DIN ISO 10072). Related tooling and moulding standards are found under ISO/TC 29/SC 8 (tooling for pressing, stamping, injection moulding and related processes).

FAQ

Q: What is this standard?

A: ISO 10072:2004 is an ISO International Standard that specifies the dimensions, tolerances, hardness and designation of sprue bushes used mainly in injection moulds for plastics and rubber.

Q: What does it cover?

A: It covers the principal external and internal dimensions of sprue bushes (in millimetres), the permissible tolerances, recommendations on material/hardness, and the standardized method of designation for these components.

Q: Who typically uses it?

A: Mould designers, toolmakers, component suppliers, procurement teams and quality/control engineers in plastics and rubber moulding industries use the standard to specify, manufacture and inspect sprue bushes.

Q: Is it current or superseded?

A: The 2004 edition (Edition 2) is the current published edition; the earlier 1993 edition was withdrawn and superseded by the 2004 edition. The ISO catalogue entry shows the 2004 edition as the active version.

Q: Is it part of a series?

A: ISO 10072:2004 is one standard within the body of tooling and mould-related standards maintained by ISO/TC 29/SC 8; it is not a multi-part series in itself but is related to other tooling standards covering components and dimensions for mould and die tooling.

Q: What are the key keywords?

A: Sprue bush, sprue bushing, injection mould, dimensions, tolerances, hardness, mould components, tooling standards (ISO 10072:2004).
