Abstract
In a method of injection molding a tie that includes an abutment wall surface having at least one tooth inside a locking head facing a pawl, a first mold part defines a portion of the abutment surface that includes the at least one abutment surface tooth and a second mold part defines at least a portion of a surface of the abutment wall that is on the opposite side of the abutment wall from the portion of the abutment surface that includes the at least one abutment surface tooth. The first mold part is separated from the second mold part while retaining the abutment wall in the first mold part to separate the second mold part from the opposite side of the abutment wall to thereby enable the abutment wall to flex in a direction away from the pawl into a space vacated by separation of the second mold part from the opposite side of the abutment wall so that the tie can be removed from the mold without significantly damaging the at least one abutment surface tooth.
