Abstract
A cable tie having a tongue with ratchet teeth on opposite broad sides of the tongue and two stationary teeth on an abutment surface opposite a hinged pawl within a locking head opening is injection molded by combining a first mold part defining a portion of a mold cavity that forms a first set of ratchet teeth on the one broad side of the tongue and a second mold part that defines a portion of the mold cavity that forms a second set of ratchet teeth on the other broad side of the tongue. The second mold part includes a core that defines at least a portion of the mold cavity that forms the opening in the locking head; and the first mold part is combined with the core of the second mold part at an interior parting surface that is remote from the portion of the mold cavity that forms the apexes of the stationary teeth. The solidified tie is ejected from the opened mold without separating the mold parts at any portion of the mold cavity that forms an apex of the stationary teeth.
