The process consists essentially of inserting a thermoplastic sheet in a cold state into the clamp area, heating it to the desired temperature with the heating elements, and then raising the buck/form/mould from below. The trapped air is evacuated with the assistance of a vacuum system. Once cooled, the platform is lowered to release the formed plastic part from the buck/form/mould. | The process consists essentially of inserting a thermoplastic sheet in a cold state into the clamp area, heating it to the desired temperature with the heating elements, and then raising the buck/form/mould from below.
