METHOD FOR PRODUCING A PLASTICS PRODUCT AND DEVICE FOR CARRYING OUT THE METHOD AND ALSO CLOSURE PRODUCT OR ADHESION PRODUCT PRODUCED BY THE METHOD AND THE DEVICE

摘要

A method for producing a plastics product consisting of a support (30) having protruding stem parts (36) which have at their free end a head part (38) having a wider diameter compared with the respective stem part (36), wherein 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), is characterized in that the shaping zone is sealed off from the environment by means of a counter-surface (20) such that a predefinable amount of air enclosed in the shaping zone exerts a counter-pressure on the plastics material introduced into the respective cavity (16) of the shaping zone in order to support the shaping process.

1. A method for producing a plastic product consisting of a support (30) having protruding stem parts (36), which have at their free end a head part (38) having a wider diameter as compared to the respective stem part (36), wherein the stem parts (36) and the head parts (38) are formed in cavities (16) of a molding screen (12), which cavities are formed on the side thereof facing away from the support (30) in a shaping zone of the molding screen (12), characterized in that the shaping zone is sealed off from the environment by means of a counter-face (20) in such a way that a predeterminable quantity of air enclosed in the shaping zone exerts a counter-pressure on the plastic material introduced into the respective cavity (16) in order to support the shaping process.
