A method of making an interior trim panel for attachment to structure of a vehicle includes the steps of loading a trim blank into a cavity of a first side of a mold and depositing a molten thermoplastic material onto a core on the first side of the mold. The method also includes the steps of closing the mold, moving the slide in a channel of the core, and injecting a molten thermoplastic material into a second side of the mold to form the interior trim panel.

1. A method of making an interior trim panel for a vehicle, said method comprising the steps of:providing a mold having a first half and a second half; providing a trim loading system on the first half; loading a trim blank into the trim loading system; moving a slide having a recess to an extended position on the second half to divide the second half into two sides; extruding a molten first thermoplastic material onto the side of the second half that is opposite the trim blank; closing the mold to bond the first thermoplastic material to the trim blank to form a cavity on the side of the second half not containing the first thermoplastic material and trim blank and disposing a blade on the first half into the recess of the extended slide; moving the slide to a retracted position; and injecting a molten second thermoplastic material into the cavity between the first half and the second half to bond the second thermoplastic material to the first thermoplastic material to form the interior trim panel. 2. A method as set forth in claim 1 wherein said step of injecting comprises providing an injection unit for injecting molten plastic into the mold.3. A method as set forth in claim 2 including the step of cooling the interior trim panel.4. A method as set forth in claim 2 including the step of opening the mold.5. A method as set forth in claim 4 including the step of removing the interior trim panel from the mold.6. A method as set forth in claim 1 including the step of pre-cutting the trim blank.7. A method as set forth in claim 1 including the step of starting one step before a previous step has been completed.8. A method of making an interior trim panel for an inner panel of a vehicle, said method comprising the steps of:providing a mold having a first half and a second half; providing a trim loading system on the first half; loading a trim blank into the trim loading system; moving a slide having a recess to an extended position on the second half to divide the second half into two sides; extruding a molten first thermoplastic material onto the side of the second half that is opposite the trim blank; closing the mold to bond the first thermoplastic material to the trim blank to form a cavity on the side of the second half not containing the first thermoplastic material and trim blank and disposing a blade on the first half into the recess of the extended slide to form a first portion of the interior trim panel; moving the slide to a retracted position; and injecting a molten second thermoplastic material into the mold and forcing the molten second plastic material into a cavity between the first half and the second half to bond the second thermoplastic material to the first thermoplastic material to form a second portion of the interior trim panel. 9. A method as set forth in claim 8 including the step of opening the mold.10. A method as set forth in claim 9 including the step of removing the interior trim panel from the mold.11. A method of making a door trim panel for attachment to an inner panel of a door of a vehicle, said method comprising the steps of:providing a mold having a first half and a second half; providing a pin frame on the first half; loading a trim blank into the pin frame; extending a slide having a recess to an extended position on the second half to divide the second half into two sides; extruding a molten first thermoplastic material onto the side of the second half that is opposite the trim blank; closing the mold to bond the first thermoplastic material to the trim blank to form a cavity on the side of the second half not containing the first thermoplastic material and trim blank and disposing a blade on the first half into the recess of the extended slide to form a first portion of the door trim panel; retracting the slide to a retracted position; and injecting a molten second thermoplastic material into the cavity between the first half and the second half and forcing the molten second thermoplastic material into the cavity to bond the second thermoplastic material to the first thermoplastic material to form a second portion of the door trim panel.
