ABSTRACT:
A method and apparatus forms a plastic part having a shape memory which has been formed to a second shape from an initial shape by the application of pressure to cause molecular orientations which are subsequently fixed by being cooled to a desired temperature and, when subjected to subsequent energy such as heating, will eliminate the molecular orientation and create a restoring force to return the part to the initial shape.
