ABSTRACT:
In a method and apparatus for injection molding a multi-component mixture, in particular liquid silicone rubber; a starting material, containing at least two components and, optionally, at least one additive, is conveyed from a storage and metering assembly through a mixer for mixing the starting material, to a reservoir at an amount which is a multiple of an amount required for an injection molding cycle. The mixed starting material is transferred in increments from the reservoir to an injection unit of an injection molding machine. When the reservoir is emptied to a predetermined level a multiple of the amount of starting material required for the injection molding cycle is fed to the reservoir.
