Abstract
A method for producing a plastic product including a support (30) having protruding stem parts (36) having at their free ends head parts (38) with a wider diameter compared with the stem parts (36). The stem parts and the head parts are formed in cavities (16) of a moulding screen (12) that are formed, on their sides facing away from the support (30) in a shaping zone of the moulding screen (12). The shaping zone is sealed off from the environment by a counter-face (20) such that a predefinable amount of air enclosed in the shaping zone exerts a counter-pressure on the plastic material introduced into the respective cavity (16) of the shaping zone to support the shaping process.
