摘要： A method of producing an injection molded part in which an insert is disposed within a mold cavity and extrusion coated with a plastic material fed via injection cylinder by layering at least one hard component and at least one soft component of a plastic material within the injection cylinder and then successively feeding the hard component followed by the soft component out of the injection cylinder into the mold cavity to extrusion coat the insert.

摘要： The invention relates to a process of and an apparatus for injection molding hollow-blown plastic bodies in which a mold cavity formed by a tool and consisting of at least one main mold cavity and one side mold cavity is filled with a pressurized flowable plastic melt and, after the setting in of the hardening of the plastic melt at the walls of the mold cavity, a pressurized fluid is introduced into the main mold cavity, and, with this, the flowable core of the plastic melt is forced out of this main mold cavity, and subsequently, a pressurized fluid is introduced into the side mold cavity by means of which the flowable core of the plastic melt is forced out of the side mold cavity into the main mold cavity, where the material still capable of flowing is deposited on the already hardened walls in the main mold cavity.

摘要： The invention relates to a process of and an apparatus for injection molding hollow-blown plastic bodies in which a mold cavity formed by a tool and consisting of at least one main mold cavity and at least one side mold cavity connected with this is filled with a pressurized flowable plastic melt and, simultaneously or after the setting in of the hardening of the walls in the main mold cavity, a pressurized fluid is introduced into the main mold cavity, as a result of which the flowable core in the main molded cavity is displaced while forming a flow front and, as soon as the flow front has reached the point of connection to the side mold cavity, a pressurized fluid is additionally introduced into the side mold cavity at the side opposite the point of connection such that the molten core in the side mold cavity is forced out together with the molten core in the main mold cavity.
