Method of and apparatus for injection molding multicomponent fiber-reinforced molded parts

To produce multicomponent molded plastic articles by injection molding, at least one component is manufactured using an injection molding compounder. A swivel platen machine with two working zones is used to produce multicomponent parts having cores or layers of fiber material or non-woven material. Fiber material may be shaped into a preform in a mold cavity in one working zone, and a preform that has been produced in a previous cycle is simultaneously encapsulated in or injected with plastic in the other working zone. The swivel platen is then rotated about its axis, transporting the preform from the one working zone into the other working zone, while the finished plastic article is removed.
