ABSTRACT:
An improved method and apparatus for effecting separation of plastic components from associated metal components where the plastic and metal components are attached to one another by fasteners, e.g., effecting separation of plastic components from a discarded manufactured product such as an automotive vehicle. The improved method comprises impacting the heads of the fasteners in a direction leading from the plastic component to the metal component, so as to cause the plastic component to rupture around the fasteners and thereby free the plastic component from the metal component. The improved apparatus is a pneumatically-powered striker device that is designed for easy alignment of its striker with the heads of the fasteners and is capable of driving its striker against said fasteners with sufficient force and acceleration to cause rupture of the plastic component around the fasteners so as to free the plastic component from the metal component.
