Abstract
A high pressure injection mixing head for mixing and ejecting plastic materials consisting of more than one component. The mixing apparatus includes at least two mixing assemblies connected at their outlet ports to a transfer cylinder of a larger diameter. The components are being mixed in the mixing assemblies and then transferred into the transfer cylinder from which the mixture is injected into a mold. The mixing chambers of the mixing assemblies and the cavity of the transfer cylinder are automatically purged when the mixing head ejects material. An entry port for additional material may be located on the transfer cylinder.
