Mixing apparatus for reactive plastic components and method of operation of such a mixing device

The invention relates to a method and apparatus for mixing reactive plastic components. The mixing device comprising at least one metering and supply means for supplying reactive synthetic starting components as well as a mixing chamber connected to the metering and supply means is connected or in which the at least two reactive starting components can be mixed together to form a reactive mixture and that of the for introducing is formed the reactive mixture in a cavity. According to the invention it is proposed that the mixing chamber is provided in the mold or molded plastic part produced in a previous production step is provided which is interposed during the Einfullbetriebs between the metering and supply means and a cavity.
