Abstract
A rigid thermoplastic polymeric sheet material forming process. The process includes heating, while under a heating vacuum range, a rigid thermoplastic polymeric sheet in a heating zone to a forming temperature to form a heated rigid thermoplastic polymeric sheet material. The process further includes transferring, while under a feeding vacuum range, the heated rigid thermoplastic polymeric sheet material from the heating zone to feed the heated rigid thermoplastic polymeric sheet material into a forming zone under the feeding vacuum range. The process also includes forming, in the forming zone, the heated rigid thermoplastic sheet material into a formed article.
