ISO 10907-2:2007

Overview

ISO 10907-2:2007 - Tools for moulding - Locating rings - Part 2 specifies the basic dimensions, tolerances and designation rules for locating rings used when mounting moulds with thermal insulating sheets in small or medium injection moulds (EUROMAP 2 types C and D). It applies to injection moulding machines up to size E12 and provides material guidelines and hardness requirements for locating rings intended for use with ISO 15600 insulating sheets.

Key topics and technical requirements

• Scope and types
  • Type C: locating rings with bore - preferred for fixed mould halves.
  • Type D: locating rings without bore - preferred for moveable mould halves.
• Dimensions and tolerances
  • Basic dimensions are given in millimetres and illustrated in figures and tables (various diameters D and bores d).
  • Typical tolerances shown in the standard include d ± 0.1 mm (bore) and t ± 0.2 mm (thickness) for specified sizes.
  • Surface roughness values are provided (in micrometres) for functional faces.
• Material and mechanical properties
  • Material shall be steel with a minimum yield strength of 370 N/mm²; specific grade chosen by the manufacturer.
  • The standard also gives hardness requirements and related material guidance (see full text for exact hardness limits).
• Compatibility
  • Thicknesses of locating rings are adapted to thermal insulating sheet thicknesses 6 mm and 10 mm as per ISO 15600.
  • Diameters conform to EUROMAP 2 mould-fixing dimensions.
• Designation
  • Standardised naming format (example):
    • Type C: “Locating ring ISO 10907-2 C - 100 × 32 × 18.5”
    • Type D: “Locating ring ISO 10907-2 D - 100 × 18.5”

Applications and users

• Used for accurate and repeatable mounting of moulds where thermal insulating sheets are installed to control thermal transfer between platen and mould.
• Primary users:
  • Toolmakers and mould designers
  • Injection moulding machine manufacturers and OEMs
  • Maintenance and mould-fitting engineers
  • Procurement and quality engineers ensuring compatibility with EUROMAP and ISO specifications
• Practical benefits: ensures interchangeability, correct fit with insulating sheets, repeatable mould alignment and reduced thermal bridging.
