Full title and description

ISO 16916:2016 — Tools for moulding — Tool specification sheet for injection moulds. This International Standard defines the content and structure of a tool-specification sheet used when requesting, tendering for and ordering injection moulds, giving required information on design, materials, interfaces, testing and delivery to ensure comparable offers and reduce misinterpretation between buyer and toolmaker.

Abstract

ISO 16916:2016 specifies the description and specification data for injection moulds: general buyer/supplier data, mould construction and surfaces, machine and mounting data, cooling/heating, ejection and demoulding systems, process monitoring, sampling and warranty information. The standard explicitly excludes compression moulds and die-casting dies.

General information

• Publication date: February 2016 (2016-02).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 25.120.30 (Tooling; moulds and dies).
• Edition / version: Edition 2 (ISO 16916:2016).
• Number of pages: 8 pages.

Scope

Defines the information and data required on a tool specification sheet for injection moulds so that buyers can request complete, comparable offers and toolmakers can deliver the defined scope of work. Covers material selection, structural design aspects, surface treatments, machine-specific data, sampling and acceptance, and contractual details such as warranty and ownership of NC programs/electrodes. Does not apply to compression moulds or die-casting dies.

Key topics and requirements

• Structure and required fields of the tool specification sheet (buyer/supplier contacts, drawings, part numbers, cavity count, prototype/production designation).
• Material, heat treatment and surface-finish requirements for mould components; marking and traceability expectations.
• Mould design choices and options: mould type, gating/hot-runner arrangements, slides and cores, cooling/heating circuits.
• Mechanical interfaces and machine mounting data: clamping, centring, lifting and adapter plates.
• Demoulding and ejection systems: ejector designs, drives, thread/core removal and special mechanisms.
• Process control, instrumentation and sampling: thermocouples, pressure transducers, position monitoring and sampling rules for acceptance.
• Order contents and scope of delivery: CAD/NC data, electrodes, standard parts, tests, samples and documentation; responsibilities for design approval and ownership of NC programs/electrodes.

Typical use and users

Used by tooling engineers, mould designers, toolmakers, OEM procurement and purchasing teams, plastics-part producers and quality/production engineers to create unambiguous procurement requests, specify tool acceptance criteria and to document design, thermal and control features for injection moulds. Also useful to maintenance and service teams for spare‑part and refurbishment planning.

Related standards

Standards referenced or relevant to ISO 16916 include documents on terminology and material grades for mould components (for example, ISO 12165 for steel grades/terms related to mould components) and other tooling/moulding standards produced within ISO/TC 29 and its subcommittees. Users often consult local machine-interface standards and hot-runner supplier specifications alongside ISO 16916.
