<p>A method for the manufacture of a plastic product, wherein a reinforcement package ( 2 ) is placed against a molding wall ( 1 ), an air extraction and a supply ( 5 ) for liquid plastic material ( 6 ) are installed, and the reinforcement package is covered by an air-tight covering ( 3 ), on which, non-detachably, channel parts ( 7 ) are fixed. The pressure in the reinforcement package is adjusted to a value d 1, lower than the ambient pressure, after which the pressure within the channel parts is adjusted to a value d 2, lower than d 1, so that runner channels are formed on the reinforcement package. After the liquid plastic material has soaked the reinforcement package to a sufficient extent, the pressure in the channel parts is adjusted to a value d 3, greater than d 1, so that the runner channels are pushed away. After curing of the plastic material, the air-tight covering-if desired reusable and premodeled-and the channel parts connected therewith are released.</p> |
