Abstract: The invention relates to a method for producing a hollow injection-moulded part, in particular a primary packaging means for medical applications by an injection moulding method, comprising the following method steps:



a) Providing a first female die tool having a first mould cavity and a mould core formed as a male die tool;
b) Introducing a mould core into the first mould cavity so that a first cavity is formed and the mould core extends beyond the mould cavity in the axial direction (X), thereby bringing the mould core into operative contact with the first female die tool and/or with a receiving member;
c) Injecting a first plastic material into the first cavity so that a first portion of the injection-moulded part is formed;
d) Transferring the first portion of the injection-moulded part to a second cavity;
e) Injecting a second plastic material into the second cavity so that a second portion is formed directly on the first portion of the injection-moulded part.
