Overview
ISO 10907-1:2008 specifies standardized locating rings used for mounting moulds without thermal insulating sheets in small or medium injection moulds. The standard defines the basic dimensions and tolerances (in millimetres) for two types of locating rings - Type A (with bore) and Type B (without bore) - intended for injection moulding machines up to size E12 (per EUROMAP 2). It also provides material guidelines, minimum mechanical strength, surface texture references and a clear designation system for ordering and documentation.
Key topics and requirements
- Scope and applicability
- Locating rings for mounting moulds without thermal insulating sheets in small/medium moulds (types A and B).
- Suitable for injection moulding machines up to EUROMAP 2 size E12.
- Dimensions and tolerances
- Basic dimensions, fits and tolerances are given in millimetres and illustrated in figures and tables (see Type A: Figures 2–4 and Table 1; Type B: Figures 5–7 and Table 2).
- Tolerance class f8 is referenced for bore/shaft fits where applicable.
- Types and typical use
- Type A (with bore) - preferably for the fixed mould half.
- Type B (without bore) - preferably for the moveable mould half.
- Material and mechanical properties
- Material shall be steel with a minimum yield strength of 370 N/mm²; specific grade and heat treatment are left to the manufacturer’s discretion.
- The standard gives guidance on hardness requirements (refer to the document for exact requirements).
- Surface texture
- Surface roughness indications updated in accordance with ISO 1302:2002.
- Designation
- Standardized naming format, e.g.:
Applications and users
- Toolmakers and mould designers specifying locating rings for new tools.
- Injection moulding machine and mould manufacturers ensuring compatibility with EUROMAP dimensioning.
- Maintenance, procurement and quality departments selecting replacement locating rings or verifying incoming parts.
- Use cases include mounting and aligning mould halves, ensuring repeatable positioning, and reducing setup time on machines up to E12 size.
