For manufacturing a moulding composed of at least two polymers with different properties, in a first process step a first liquid polymer is introduced with cooling, for example by means of a feed device (20), into a heated injection mould. This polymer is allowed to remain there until it achieves sufficient dimensional stability for further process steps to be carried out. The temperature of the first polymer and/or the residence time are adjusted in such a manner that crosslinking of the polymer still does not occur. Subsequently, in a second process step, a second liquid polymer with properties different from those of the first polymer is introduced into the heated injection mould with cooling, for example by means of a feed device (24). The first and the second polymer are then crosslinked together in the injection mould heated at least to crosslinking temperature. An inseparable bond is thus formed between the two in the areas adjacent to one another. <IMAGE>
