Method for manufacturing a wall connector |
摘要 |
The method for the manufacture of wall connector pieces is based on a thin-walled tubular blank which is first reduced in diameter at least one, preferably both ends in order to increase the wall thickness. In this way, a basis is provided for further shaping, for example, the manufacture of a connector piece (4) or a closed end (5).
