摘要：
The invention relates to an apparatus for carrying out a resin transfer moulding (RTM) process and to an RTM process for producing in particular integral components, wherein the apparatus has an injection unit (10) and a closable mould (W) provided with a mould cavity (F), and the injection unit (10) can be coupled to the mould (W) in such a manner that an injection resin can be introduced into the mould (W), wherein the mould (W) has at least one resin outlet (3), which can be closed by means of a resin flow closing unit (5), is connected to the mould cavity (F) and from which injection resin can escape after the mould has been filled, wherein a measurement unit which detects the flow of resin escaping is arranged at or downstream of the resin outlet and is coupled to the resin flow closing unit (5) in such a way that the resin flow closing unit (5) closes if resin flow is detected by means of the measurement unit. In terms of the process, a signal for closing the resin flow closing unit (5) is output to the resin flow closing unit (5) via a control system (11) if resin flow is detected by means of the measurement unit, said resin flow closing unit is closed and the flow of resin escaping from the mould (W) is interrupted.
