A mold for an injection molded applicator head comprising a number, M, of separable mold sections, wherein: each mold section fills an angle of 360°/M, and comprises an interior face, a flat lateral face, and a sculpted lateral face; when assembled each flat lateral face contacts the sculpted lateral face of an adjacent mold section, while the interior faces define a core space that has a longitudinal axis that extends along the length of the core space; the sculpted lateral faces are flat except for a number of bristle spaces cut into them; the flat lateral faces of adjacent mold sections are oriented to each other at an angle γ=360°/M degrees; the bristle spaces extend radially from the core space, and are regularly arranged in M columns that extend down the core space, parallel to the longitudinal axis; at least some of the bristle spaces comprise one or more protrusions that contact the flat lateral face of an adjacent mold section, and that is fashioned with a draft angle on the distal end of the protrusion.
