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.

A rigid thermoplastic polymeric sheet material forming process comprising:
- heating, while under a heating vacuum range, a rigid thermoplastic polymeric sheet in one or more heating zones to a forming temperature to form a heated thermoplastic polymeric sheet material;
- and
- transferring, while under a feeding vacuum range, the heated thermoplastic polymeric sheet material from the one or more heating zones to feed the heated thermoplastic polymeric sheet material into a forming zone under the feeding vacuum range;
- and
- forming, in the forming zone, the heated thermoplastic polymeric sheet material into a formed article, the forming zone includes a forming chamber including a shroud, a crown, and a bed, the crown and the bed are fixedly connected to the shroud to seal the forming chamber.
