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 is formed in a mold that defines a tie in which the abutment wall includes at least one bulge adjacent each of opposite ends of the abutment wall for holding the abutment wall in the respective mold parts when the mold parts are first separated, with the at least one bulge adjacent one end of the abutment wall being defined by a first mold part and the at least one bulge adjacent the opposite end of the abutment wall being defined by a second mold part. As the first and second mold parts are being separated, the bulges initially hold the abutment wall in the respective first and second mold parts and thereby stretch and reduce the thickness of the abutment wall so that the tie can be removed from the mold without significantly damaging the at least one abutment surface tooth.
