Abstract
Methods of making interior panels having integrated airbag deployment doors for motor vehicles are provided. In one example, a method of making an interior panel comprises contacting a molten resin in a molding tool cavity with a plurality of juxtaposed pressurized gas streams to form a series of holes, bubbles, knit lines, or combinations thereof in the molten resin. The molten resin is solidified to form a substrate. The series of holes, bubbles, knit lines, or combinations thereof define a frangible tear seam in the substrate.
