Claim:
1. A method for releasing a vehicle bumper fascia, wherein the bumper fascia comprises a wing portion at one end, a wheel well flange and a mounting rib extended from the wing portion, the method comprising: providing a mold comprising a primary mold core, a first movable mold core slidingly engaged to the primary mold core, a second movable mold core slidingly engaged to the first movable mold core, and a third movable mold core slidingly engaged to the second mold core, wherein the primary mold core and the first movable mold core together define a first cavity for forming the mounting rib of the bumper fascia, wherein an exterior surface of the first movable mold core defines a portion of a second cavity for forming the wing portion of the bumper fascia, and wherein the second movable mold core and the third movable mold core together define a third cavity for forming the wheel well flange of the bumper fascia, wherein the first movable mold core is divided into a first section and a second section, and the first section of the first movable mold core produces a first portion of the mounting rib along a first region of the wing portion that is contacted by the second movable mold core, and the second section of the first movable mold core produces a second portion of the mounting rib along a second region of the wing portion that is not contacted by the second movable mold core; disengaging the third movable mold core from the second movable mold core to release the wheel well flange of the bumper fascia from the third movable mold core; disengaging the first movable mold core and the second movable mold core together from the primary mold core to release the mounting rib of the bumper fascia from the primary mold core, wherein the first movable mold core remains engaged with the second movable mold core; and disengaging the second movable mold core from the first movable mold core to release the wing portion of the bumper fascia and the mounting rib from the first movable mold core.
