MANUFACTURING METHOD FOR A PLUNGER AND SUCH A PLUNGER

摘要

A plunger (9) has, when viewed in a longitudinal direction (x), a central region (15) and two outer regions (16, 17) adjoining the central region (15). The outer regions (16, 17) are injection-moulded from a non-magnetizable material. In the central region (15), a magnetizable material is integrated in the plunger (9). Preferably, an injection-mouldable material is used as the magnetizable material, and the plunger (9) including the magnetizable material is manufactured by means of a two-component injection-moulding process. A defined magnetization is impressed on a section (18, 19) of the central region (15) once the magnetizable material has been integrated in the plunger (9).
