UN METODO DE CONFORMAR MATERIAL TERMOPLASTICO. |
摘要 |
<p>A two-stage thermoforming operation is described which relies upon temperature variations and mold configurations to lock in a desired shaped article of polymeric material having a reduced tendency to distort upon removal from a thermforming operation. The mold configurations and sequence used permit deep draw forming without fracture of the polymeric material.</p> |
