Abstract
A method for producing a thermoplastic panel, including the steps of providing a rotary injection tool exhibiting a die cavity and featuring at least one lifter component within the cavity. The tool is positioned to orient the cavity in a first configuration during which a first shot injection molding of a doghouse is conducted onto a receiving location of the lifter component. The cavity is open and the tool rotated to reposition the cavity in a second configuration, following which a second shot injection molding operation is conducted for forming a skin of the panel in communication with the first shot doghouse clip. Following this, the mold is opened and the finished part removed.
