Abstract

The invention relates to a form part for manufacturing a single or double-curved surface through the thermoforming of a thermoplastic material, including a body (3) that on its active form-shaping outer side (4) or outer periphery is provided with a number of openings (5), so-called evacuation holes, arranged to join with a source for generating negative pressure for evacuating air enclosed between the body and the plastic material shaped against this. To achieve form parts that are significantly cheaper and lighter than form parts known to date for thermoforming of thermoplastics, a separate connection with the source of the negative pressure is arranged for each opening (5).
