Materials Mould Seals

Mould Seals

A comprehensive range of mould seals and ‘formers’ used in the mould-making process.

The D section resin seal is available in three versions with varying levels of compressibility.
All standard seals have a maximum service temperature of 200°C.
This allows the majority of moulds to be built with a standard seal groove but still enables some flexibility in seal specification and performance.

Mould Seal Options
Mould Seal 10 x 5 with Radius (12.5mm overall height) (RD-20-0009)
Seal for use with small RTM applications– where standard ‘D’ seal is not applicable. Silicone Type: General purpose, 55 shore hardness.
D Section Mould Seal– White Inflatable (RD-20-0010)
D section mould seal for use as a resin seal in RTM or ‘Light RTM’ moulds, to reduce seal drag when closing the mould where flanges are too steep for conventional seals. The seal is inflated or collapsed under vacuum using seal control unit XE-0400. Silicone Type: General purpose, 55 shore hardness.
D Section Mould Seal - Green (RD-20-0011)
Harder more resilient version of standard D seal for use in high-pressure RTM applications. Silicone Type: General purpose, 55 shore hardness.
D Section Mould seal – Blue (RD-20-0013)
Standard D section mould seal for use as a resin seal in the majority of Light RTM / RTM tooling. Note: this seal is also used during the mould construction to generate the correct seal groove) Silicone Type: General purpose, 55 shore hardness.
Lip Section Mould Seal - Blue (RD-20-0012)
‘Lip’ section vacuum seal for use as an outer vacuum seal in ‘Light RTM’ moulds. Silicone Type: General purpose, 55 shore hardness.
Small Lip Section Mould Seal - Blue (RD-20-0014)
Similar section to standard Lip section seal RD-20-0012, but approx half size. Can be used for vacuum applications where small bend radii are required. Also used to retain mould-insert blocks under vacuum. Silicone Type: General purpose, 55 shore hardness.
Resin Runner Profile (RD-20-0016)
Silicon section to provide correct resin-runner detail, during VRTM mould manufacture. Can be formed around horizontal and vertical radii. Silicone Type: General purpose, 55 shore hardness.
Foam Silicone Groove Profile (RD-20-0017)
Foam silicone section to provide correct groove, during mould manufacture, for fitting of RD-20-0012 lip section mould seal. Easily formed around horizontal and vertical radii. Corners rounded for easy laminating during the mould making process.
