Abstract

There is proposed a method for producing a plastics component, preferably a fibre-reinforced component, an injection device (1) for carrying out the method and a manufacturing system which comprises the injection device (1) and a tool (5), wherein the method comprises the following method steps: A) injecting at least one liquid material by means of at least the injection device (1) into a cavity (5a), which cavity is formed by the tool (5); B) ejecting the produced component from the tool (5) by means of at least one ejection element (2, 9, 11); wherein the method is characterized in that in method step B at least a part-element of the injection device (1) is used as the ejection element (2, 9, 11) and is moved in relation to the tool (5).
