Abstract
A copper blank is provided with bores, and copper plugs are used to obtain blind bores. The plugs are connected to the blank in a variety of ways and are either placed centrally or at the bore ends; in the latter case, two such elements are interconnected back-to-back, possibly under inclusion of a solid center. In the former case, the plugs are soldered or brazed, preferably during annealing. In either case, a hollow drawing for sizing completes to process.
