Resin supply system in which resin material is stored in a pouch in a degassed state ready for use. The pouch comprises a body portion forming a reservoir for resin material and a connector portion in fluid communication therewith. The connector portion includes an outlet which is configured to be connected to an injector head of an injector assembly, the injector head being connectable to a mould by means of connecting tubing to provide a resin supply thereto. The pouch is configured to be mountable in a housing of the injector assembly and is compressed by hydrostatic pressure of water surrounding the pouch in a chamber of the housing. The application of pressure by a piston moving in a direction transfers pressure to the water and then to the pouch in a controlled manner to provide the resin supply to the mould. After use, the pouch is removed and discarded thereby substantially eliminating the need for cleaning of the housing after use.

Resin supply system in which resin material is stored in a pouch (120) in a degassed state ready for use. The pouch comprises a body portion (122) forming a reservoir for resin material and a connector portion (125) in fluid communication therewith. The connector portion includes an outlet (127) which is configured to be connected to an injector head (180) of an injector assembly (100), the injector head being connectable to a mould by means of connecting tubing to provide a resin supply (130) thereto. The pouch is configured to be mountable in a housing (110) of the injector assembly and is compressed by hydrostatic pressure of water surrounding the pouch in a chamber (115) of the housing. The application of pressure by a piston (150) moving in a direction (155) transfers pressure to the water and then to the pouch in a controlled manner to provide the resin supply to the mould. After use, the pouch is removed and discarded thereby substantially eliminating the need for cleaning of the housing after use.
