Overview - What ISO 24233:2008 covers
ISO 24233:2008 specifies a standardized tool specification sheet for diecasting dies to be used at the tendering (request) stage and when ordering tools. The sheet captures the essential data needed for material acquisition, equipment selection and the structural design of diecasting dies - including tool surfaces, machine‑specific data, types of operation, sampling and warranty. This International Standard is explicitly not applicable to compression moulds or injection moulds. An electronic version of the specification sheet is available from the ISO catalogue (http://standards.iso.org/iso/24233).
Key topics and technical requirements
The standard organizes the specification sheet around practical, technical topics to ensure clear communication between buyer and supplier:
- General information: customer, contact, drawings, part counts, prototype vs production tools.
- Requirements / guidelines: die design approval prior to material purchase, production of cores/cavities to drawing, sampling with the specified alloy, verification in full automatic cycle, and ownership transfer of electrodes/CNC programs and original documents to the orderer.
- Description of die order: which drawings, CAD data (2D/3D), samples, raw material and master patterns are provided by customer or supplier.
- Diecasting die design: die type (hot/chamber, cold/chamber, vertical/horizontal), casting parameters (locking force, cavity filling time, gate sizes, casting volume), design of cavity and forces during casting.
- Set-up and transport: lifting, centring, clamping, adapter plates and standards for installation on machine.
- Casting and venting systems: gating, venting, vacuum accessories, and multiple‑cavity considerations.
- Cooling/heating: expected die temperatures, cooled/heated components, number of circuits and connecting nipples.
- Demoulding and loose parts: slides, ejectors, angle ejectors, thread removal methods and securing/removal of loose parts.
- Deliverables: NC programs, electrodes, die type plate, test reports and machine data sheets.
Practical applications - who uses ISO 24233
ISO 24233 is intended for:
- Toolmakers and die manufacturers preparing offers and producing diecasting dies.
- Diecasters and production engineers verifying die suitability and integration with diecasting machines.
- Procurement and tendering teams comparing supplier offers and defining clear purchase orders.
- Design and quality engineers specifying cooling, gating and demoulding requirements and ensuring sampling and acceptance tests.
Using this standard reduces misunderstandings, allows objective comparison of offers, and helps ensure reliable die performance in production.
