Abstract:
1. A method for producing a brush head section for an oral care device comprising the steps of: injecting a first thermoplastic material into an insert-forming mold cavity to form an insert; transferring said insert into an over-molding mold cavity, wherein the insert is arranged partially inside and partially outside of said over-molding mold cavity; arranging one end of at least one cleaning element in said over-molding mold cavity, wherein the at least one cleaning element is arranged partially inside and partially outside of said over-molding mold cavity and wherein the at least one cleaning element is arranged within a mold bar in that the ends of the at least one cleaning element intended to clean are located inside the mold bar and the ends intended to be mounted into the brush head protrudes from the mold bar; injecting a second thermoplastic material into said over-molding mold cavity so that the part of the insert and the part of the at least one cleaning element which are located inside said over-molding mold cavity are over-molded by the second thermoplastic material, which second thermoplastic material thereby forms a cleaning element carrier, wherein the insert has a section behind which the cleaning element carrier engages the insert, wherein the insert comprises a coupling element or a part of a driving system of the oral care device, and wherein the hardness of the second thermoplastic material is smaller than the hardness of the first thermoplastic material; and ejecting the resulting brush head section from said over-molding mold cavity, wherein the brush head section remains in the mold bar.
