摘要： In a method of microcellular injection molding, a polymer and a supercritical fluid are processed. A condition of processing the polymer and/or the supercritical fluid is adjusted to control a weight of a plastic part and/or a surface characteristic of a plastic part produced. In another method of producing a plastic part using microcellular injection molding, a polymer is heated and melted and a supercritical fluid is added thereto. The resulting mix is a single-phase polymer-gas solution comprising the polymer and the supercritical fluid. The polymer and/or the supercritical fluid are adjusted to control the weight of the plastic part and/or a surface characteristic of the plastic part. Once adjusted, the melted polymer with the supercritical fluid is injected into a mold. Upon injecting the melted polymer and supercritical fluid, a pressure drop causes the supercritical fluid to nucleate in the melted polymer, thereby causing nucleation of bubbles.

摘要： An injection molding quality control system which seeks to ensure greater accuracy and consistency in parts, more specifically more accurate and consistent part weight, utilizes measured part weight to adjust mold separation to better achieve a desired part weight. The mold separation is controlled via both a cycle-to-cycle adjustment in switchover point (preferably based on injected mass within the cavity), and within-cycle adjustment of holding pressure. The system can result in superior accuracy and consistency in molded parts in both the long term (i.e., over many cycles) and in the short term (from cycle to cycle).

摘要： A metal matrix nanocomposite is formed by heating a metal above its liquidus temperature, adding nanoparticles, and then agitating the mixture with high-frequency (and preferably ultrasonic) vibration. The mixture can then be cooled below the liquidus of the metal to a semisolid state, and placed in a mold to form it into some desired shape. The formed mixture can then be quenched or otherwise allowed to cool to provide an article in finished (or nearly so) form.

摘要： A method is provided of fabricating a composite incorporating fillers. The method includes the steps of depositing the fillers in a matrix material either in a rapid prototyping device or prior to inserting the matrix material into a mold. The mold is positioned at a desired location with respect to an electrical field such that at least a portion of the fillers in the matrix material align in a first direction in response thereto. For producing a heterogeneous composite through a rapid prototyping process, the electrodes are positioned at a desired orientation to align the fillers. Thereafter, at least a portion of the matrix material is cured with desirable filler orientation. The procedure is repeated with the desired filler orientation and distribution being introduced layer by layer within the composite.

摘要： A process for the manufacture of a plastic part, the process comprising providing a polymer, heating the polymer, introducing a gas or supercritical fluid into the polymer, mixing the polymer and the gas to produce a first melt, extruding the first melt, pelletizing the extruded first melt to form pellets, transforming the pellets into a second melt, and molding the second melt to form the plastic part. In pelletizing the first melt, individual cells of gas are included in the resulting pellets. Before the cells can nucleate, the polymer is solidified to keep the gas contained therein. After the polymer is pelletized, the pellets are considered to be unfoamed. In molding the second melt to form the plastic part, nucleation of the cells is initiated through favorable process conditions and/or additional cell nucleating agents, thereby resulting in the second melt being foamed.
