PRESSURE HOLDING DEVICE FOR PRODUCING COMPOSITE COMPONENTS BY THE INJECTION MOULDING OF RESIN, AND ASSOCIATED METHOD

摘要

The present invention relates to a pressure holding device (10a, 10b) for a resin-injection system (100) comprising an injection network connected to an injection mould (20), characterized in that it comprises pressurizing means suited to injecting a pressurized gas into a pipeline (64); a first coupling means (11) designed to be connected to said resin injection network and designed to be connected to said pipeline (64); a second coupling means (12) designed to be connected to said injection mould (20) of said injection system (100); said first coupling means (11) being coupled to said second coupling means (11) by a pressure holding pipeline (13) designed to receive said pressurized injected gas.
