THERMOFORMING STAMPING
A low-pressure process that uses consolidated sheet.

Key Processing Points:
- Control tool temperature to the correct temperature to give the desired crystalinity.
- Heat COMFIL® min. 25 degree C over the melting temperature of the matrix material in an oven or by contact heating.
- Transport the molten COMFIL® fast from the heating to the mould to prevent the matrix from cooling prior to mould closing (5 - 10 seconds).
- Close mould fast to ensure that parts are formed prior to matrix solidification.
- Remove part from mould after part has cooled to below 50-100°C.
- Thermoplastic light cores can be added in the stamping (compression) process to form three-dimensional sandwich structures.
- Surface films or textiles can be added to the part in the stamping tool to enhance surface aspect.
