  • MANDREL: A bar, serving as a core, around which rubber is extruded. Forms a center hole to the part.
  • MITER LOCK GATE: A gate that consists of two leaves hinged at the outer ends. The two leaves meet at an angle pointing upstream, resembling a miter joing — the joining of two parts, usually at a 45° angle, to form a corner. These gates are usually sealed at the bottom and may also have partial rubber sealing a both the miter/center and hinge/pintle ends.
