Apparatus for a mold vacuum system and method of forming a sheet utilizing the system |
摘要 |
A method and an apparatus to form a sheet of polymeric material have first and second mold halves which clamp together on a polymeric sheet. A vacuum mechanism draws the sheet into an interior space. The vacuum mechanism has a plurality of controllable vacuum ports positioned about the interior space to direct the vacuum at specific portions of the sheet.
