MULTI-MATERIAL INJECTION MOLDING APPARATUS AND METHOD

摘要

A multi-material injection molding machine includes stationary and moving platens holding cores and first and second injection units for delivering first and second molding materials. The moving platen is slidable towards and away from the stationary platen. Further provided is a rotational distributi on unit movable between the stationary platen and the moving platen and defining first cavities on one side and second cavities on an opposite side. The first cavities are for mating with cores to define first mold cavities a nd the second cavities are for mating with cores to define second mold cavities . Also provided are a rotational actuator for rotating the rotational distribution unit and a molding material delivery apparatus for delivering one or more of the first molding material to the first cavities and the second molding material to the second cavities.
