Abstract
A molded plastic garment hanger constituted from first and second plastic materials which are fused and mechanically bonded to form a composite garment hanger. A coinjected plastic member formed of the second plastic material is molded into the plastic body member formed of the first plastic material, and is secured thereto by a plume of the second plastic material of the coinjected plastic member which is formed as the second plastic material is coinjected and breaches the surface of the first plastic material of the molded plastic body member which is not completely set and hardened, such that the plume of the second plastic material extends into and is secured and anchored into the first plastic material. A method and apparatus for co-injection molding of plastic materials for the formation of the plastic garment hanger construction are also disclosed.
