Process for producing a moulding from a polyamide moulding composition with improved hydrolysis resistance

A process for producing a moulding, comprising:

• mixing a polyamide having amino end groups and an oligo- or polycarbodiimide to prepare a moulding composition;
• optionally, storing the prepared composition, transporting the prepared composition or storing and transporting the prepared composition;
• processing the moulding composition to obtain a moulding having cumulative condensation;
• wherein
• at least 50% of end groups of the polyamide are amino groups,.
• a content of the oligo- or polycarbodiimide is 0.1 to 5% by weight, based on the polyamide moulding composition, and
• the cumulative condensation is obtained only during the processing to form the moulding.
