Local reinforcement of injection moldings

A method for using an injection mold for manufacturing plastic components, the injection mold including at least one sprue plate, a push-in device and an ejector plate, at least one cavity being provided between the sprue plate and the ejector plate when the sprue plate and the ejector plate are in an assembled state, the ejector plate including at least one fiber channel, at least one fiber bundle having a thermoplastic matrix being transportable to the cavity via the at least one fiber channel, with the aid of the push-in device, along at least part of the sprue plate, the method comprising the following steps:

• assembling the sprue plate and the ejector plate;
• heating the at least one fiber bundle together with the thermoplastic matrix;
• positioning the at least one fiber bundle at the cavity with the aid of the push-in device;
• introducing a liquid plastic into the cavity through at least one sprue channel of the sprue plate;
• and
• introducing the at least one fiber bundle into the cavity, so that the fiber bundle is positioned in the cavity by the stream of liquid plastic.
