摘要： Injection molding systems and methods useful for making microcellular foamed materials are provided as well as microcellular articles. Pressure drop rate and shear rate are important features in some embodiments, and the invention provides systems for controlling these parameters in an injection molding system. Another aspect involves an injection molding system including a nucleator that is upstream of a pressurized mold. Another aspect involves an extrusion system with the reciprocating screw for forming a single phase solution of non-nucleated blowing agent and polymeric material. Another aspect involves very thin walled microcellular material and very thin walled polymeric material. Another aspect provides a method for producing high weight reductions in very thin-walled parts with surfaces that have no noticeable differences from non-foamed parts.

摘要： An apparatus for injection molding two compatible polymeric materials, in which two substantially coaxial extrusion screws are used to plasticize the two materials into a common accumulation space. The charge comprising multiple layers of material is then injected into a closed mold by means of forward axial motion of the outer screw with respect to its enclosing barrel. Once inside the mold, the first material forms a skin layer totally or partially surrounding the other material. In this way a part having a plurality of material properties may be produced in a single operation.

摘要： According to the present invention an in-line compounding/extrusion deposition and molding apparatus and method of using the same are provided. The apparatus comprises a single step compounding and extrusion apparatus which includes an extruder screw. The apparatus includes a first zone, a second zone, and a third zone. The first zone is used to melt an inlet material before the screw advances the melted inlet material into the second zone which comprises a preparation and cutting zone. Simultaneously, as the inlet material is melted in the first zone, the screw rotation feeds a reinforcing fiber bundle into the second zone where the reinforcing fiber bundle is prepared for melt impregnation and is sheared to a desired length. While in the second zone, mixing begins between the melted inlet material and the sheared reinforcing fiber bundle. Next the mixture is advanced into the third zone for uniform distributive mixing and impregnation of the sheared reinforcing fiber bundle with the melted inlet material to form a fiber bundle filled melt. The apparatus includes at least one winding/unwinding reel which continuously ensures that the reinforcing fiber bundle is under constant tension (no sagging or breaking thereof) during the X, Y, Z movement of the apparatus during melt deposition as well as during forward movement of the screw within the barrel.

摘要： A system is disclosed for molding parts. The system comprises a plasticator and press. The plasticator is capable of receiving a plurality of molding materials comprising a predetermined amount of a polyester, at least one other carbocylic and reinforcing fiber, such as glass fiber. The plasticator is characterized in that it is capable of simultaneously receiving contaminated molding materials and relatively long glass fibers and molding them into a billet wherein the fibers remain substantially undamaged. The billet is subsequently in a compression molding press where other materials may be molded or applied to its surface. The system is further characterized in that a single thermal rise is used to plasticate the molding materials. The system comprises a plasticator having a screw, a screw drive system, a plurality of heaters and control system to control the pressure and temperature in a barrel of the plasticator so as to create a billet having certain predetermined billet characteristics (such as a desired volume and/or density).
