MACHINE AND METHOD FOR INJECTION MOLDING MULTILAYER ARTICLES HAVING A HIGH PROPORTION OF INTERNAL LAYER MATERIAL
In one aspect, a method of coinjection molding a multilayer article using a coinjection nozzle having inner outlet, an outer outlet, and an intermediate outlet between the inner and outer outlets is provided. A stream of surface layer material is injected into a mold cavity from the intermediate outlet. With the injection ongoing, two streams of internal layer material are injected from the inner and outer outlets of the coinjection nozzle respectively. The two streams sandwich the stream of surface layer material and flow behind a melt front of the surface layer material. The sandwiched stream of surface layer material continues to supply the melt front with surface layer material at least until the melt front nears a distal end of the mold cavity. The resultant article is substantially or entirely encapsulated by a skin of the surface layer material and contains a high proportion of internal layer material.
