    Abstract: A method and apparatus for injection molding plastic parts is described. In one embodiment, at least two materials are simultaneously injected into a mold. The resulting molded part can include at least two different regions. Each region can have distinct physical properties. Positions of the regions within the molded part can be at least partially controlled by controlling flow fronts of the at least two materials within the mold.
