Abstract
The method concerns production of a thread insert (5) with an internal (7) in a component (1) provided with an internal thread (2) or a similar feature. The method is characterised by the following facts: a) a core (3) is inserted into the internal thread (2) of the component (1); b) a space (4) corresponding to the thread insert (5) is formed between the core (3) and the tread (2); c) the space (4) is filled by a casting process. USE - In joints subjected to severe mechanical and thermal loading, temperature fluctuations, vibrations, impacts etc. ADVANTAGE - Thread inserts are produced in a more cost-effective manner.
