In a process for mfg. a thermoformed prod. comprising a plastic substrate (26), e.g. a thermoplastic sheet, plastic mixture or a plastic matrix and a deformable facing strip (24), the facing strip (24) is positioned between the sheet (26) and the forming tool (10) prior to the forming stage in which the vacuum forming pressure is assisted by positive air pressure on the other side of the substrate (26). |
