Abstract
The method for manufacturing a solid housing, in particular a valve housing for an electromagnetically operable valve, is characterized in that the following method steps are used: a) providing a sheet metal strip made of a magnetic or magnetizable material, b) introducing an additive into a middle area of the sheet metal strip and fusing there for forming a non-magnetizable structure, c) cutting the sheet metal strip into a sheet metal piece of desired width, d) deforming the sheet metal piece into a sleeve shape, e) mutual fastening of the cut edges now facing each other and running in the longitudinal direction of the sleeve for forming a sleeve blank, f) final machining of the sleeve blank until a desired geometry of the housing is achieved. The housing is suitable in particular for use in fuel injectors in fuel injector systems of mixture-compressing spark-ignition internal combustion engines.
