ISO 15600:2000 PDF

Overview

ISO 15600:2000 specifies the basic dimensions and tolerances, material guidance and design requirements for type A and B thermal insulating sheets used in plastic and rubber injection moulds. These sheets are intended for applications where heat transmission between the injection mould and the machine platen must be reduced. Dimensions are expressed in millimetres and were chosen to match mould plate sizes specified in ISO 6753-2.

Key Topics

• Scope and purpose: Defines sizes, tolerances and designation conventions for thermal insulating sheets used in moulding tools. The sheets reduce heat transfer between the mould and platen.
• Types: Two sheet types are covered - Type A and Type B - with a table of standard dimensions and tolerances for each size.
• Dimensions and tolerances: Standard nominal sizes (length, width, thickness) and allowable tolerances are specified to ensure interchangeability with machined mould plates.
• Mounting details: For type B sheets of 156 mm × 156 mm and larger, hole diameters are matched to the fitting diameter of locating rings (≤ 90 mm). For smaller type B sheets the hole diameter is left to the manufacturer’s discretion.
• Material guidance: The standard leaves the exact material selection to the manufacturer but specifies performance requirements.
• Design requirements: Includes minimum compressive strength values and a maximum thermal conductivity limit as performance criteria:
  • Compressive strength: minimum 170 N/mm at 140 °C and 100 N/mm at 200 °C (as stated in the standard).
  • Coefficient of thermal conductivity: maximum 0,3 W/mK.
• Designation rules: Sheets are designated by the term “Thermal insulating sheet”, reference to ISO 15600, type (A or B), and the length × width × thickness in millimetres.
  • Example: Thermal insulating sheet ISO 15600 A - 96×96 6

Applications

• Reduction of heat transmission between injection moulds and machine platens.
• Use in plastic and rubber moulding processes where temperature control is critical to part quality.
• Direct interchange with standard machined mould plates where dimensional conformity is required.
