Abstract
A tie including a tongue and a locking head having a pawl that is hinged at one side of an opening in the locking head across the opening from an abutment surface for locking engagement with a first set of ratchet teeth on one side of the tongue when the tongue has been inserted through the opening, and also having teeth on the abutment surface for locking engagement with a second set of ratchet teeth on the other side of the tongue when the tongue has been so inserted, is formed by injection molding. An artifact line is formed at a parting line between the mold parts while the plastic material solidifies in the mold cavity. Removal of the injection-molded tie from the mold parts without significant damage to the abutment surface teeth as the mold parts are being separated in a direction normal to the parting line is facilitated by the direction of insertion being at an obtuse angle to an extension of the artifact line from the abutment surface toward the pawl, by the facing surface of each abutment surface tooth extending in a direction away from the artifact line at a non-acute angle with respect to the extension of the artifact line from the abutment surface toward the pawl, and by an extension of the locking surface of each abutment surface tooth from the abutment surface being at an acute angle with respect to the extension of the artifact line from the abutment surface toward the pawl.
