Abstract: Method and apparatus for molding and assembling a composition part assembly in, for example, a plastic injection-molding machine. Complementary mold portions associated with a mold plate and rotatable turret form plural parts. Assembly apparatus associated with the turret assembles the plural parts into an assembly. A further turret may be provided to add a complementary part to the assembly to make a final assembly. The method includes manufacture of composite part assemblies and final assemblies.
