Abstract
A method for manufacturing an injection-molded first component of an article, in particular a handle or a head of a toothbrush, having a sheath element with a cavity and a recess extending from the cavity into a wall of the sheath element surrounding the cavity, including the steps of: (1) providing a first mold having first mold components that define a first mold cavity in the form of a pre-sheath element having a through hole in the pre-sheath element at the location where the recess shall be formed, (2) injection-molding of the pre-sheath element using a first plastic material, (3) closing the through-hole with a lid element, (4) providing a second mold having second mold components for receiving the pre-sheath element and for defining a remaining second mold cavity that extends at least over a part of a parting line between the lid element and the pre-sheath element when the pre-sheath element is inserted in the second mold, (5) inserting the pre-sheath element into the second mold, and (6) connecting the lid element with the pre-sheath element by injecting a second plastic material into the remaining second mold cavity such that the sheath element is formed.
