| Thermoforming
is a method of processing plastic resin into finished parts from sheet (0.010"
[0.254 mm] thick and greater) or film (less than 0.010" [0.254 mm] thick.) The
plastic sheet is heated to its particular thermoforming temperature and
immediately shaped to the desired configuration. At |
|
processing temperatures the sheet is very pliable, enabling it to be formed
rapidly into great detail with a minimum of force. Pressure is maintained until
the part has cooled. It is then trimmed of the selvage used to hold the sheet
during processing. |
