The invention relates to a method of vacuum casting with a multicomponent material, comprising the steps of: preparing the multicomponent material and pouring it into a mould in a vacuum atmosphere, the preparation comprising a method for repeatedly preparing a multicomponent material, with the step of: mixing at least two components, the step further comprising: feeding degassed components from reservoirs (13, 34), in which the components for a number of cycles are stored in a degassed form. Furthermore, the invention relates to a vacuum casting installation (1) for producing a product of plastics material, comprising: a vacuum chamber (2) for creating a vacuum atmosphere, wherein a mixing head (15) for mixing a number of components is arranged in the vacuum chamber (2), comprising: at least one mixing chamber (16), at least one feeding device (22) for feeding the components, wherein the mixing head (15) comprises lines (23) and/or adjusting means (24) for regulating and/or controlling a material flow of the components to be fed, which are at least partly designed for operation in a vacuum atmosphere. |
