1. A method of molding a component for an interior of a vehicle comprising:
- providing a mold assembly having a first mold half, a retractable core positioned within the first mold half, and a second mold half cooperating with the first mold half to define a mold cavity;
positioning the retractable core in an extended position so as to engage a portion of the second mold half and divide the mold cavity into a first chamber and a second chamber;
injecting a first shot of material into the first chamber and forming a sloped surface adjacent to a leading edge of the first shot of material;
moving the retractable core to a retracted position to effectively enlarge the second chamber and expose the sloped surface of the first shot; and
injecting a second shot of material into the enlarged second chamber so that the second shot of material flows between the first shot of material and the retractable core and engages the sloped surface of the first shot.

Abstract
A mold assembly, a method of molding, and a molded component for an interior of a vehicle using two shots of material. The mold assembly includes first and second mold halves cooperating to define a cavity. One of the mold halves includes a retractable core. The second mold half defines a divider for engaging the retractable core, when the retractable core is extended, so as to divide the mold cavity into first and second chambers. Portions of the core cooperate to define a sloped surface on the first shot that aids in inhibiting flash forming as the second shot is introduced into the mold assembly.
