description A method for producing a toothbrush head comprises providing at least two bristle tufts that differ in at least one property; arranging the tufts in a hole-perforation plate comprising holes shaped and distributed according to the desired bristle field; arranging an energy source so that the ends of the bristle tufts and the energy source are arranged contactless, wherein the ends of the bristle tufts to be fused are arranged at different distances to the energy source and are adjusted according to the different property; applying energy to the ends of the bristle tufts until fuse balls are formed; transferring the bristle tufts to a subsequent process position, wherein the distance of the fuse ball of at least one bristle tuft to the hole-perforation plate is different from the distance of said fuse ball to the hole-perforation plate in the fusing position before; over-molding of the fuse balls of the bristle tufts with plastic material thereby forming the brush head or the part (10) thereof.
