  • Patent number: 10850434
    Abstract: Aspects hereof provide methods for molding a single-phase solution comprised of a polymer composition and a gas. The polymer composition and the gas are maintained under pressure during the molding operation to prevent a cellular structure from being formed by the dissolved gas in the polymer composition coming out of solution. The mold cavity in which the single-phase solution is introduced for molding purposes is pressurized to a mold pressure that is sufficient to maintain the single-phase solution as a single-phase solution as the mold cavity is filled. Subsequent to filling the mold cavity with the single-phase solution under pressure, the resulting article may solidify entrapping the compressed gas, or the article may be exposed to a reduction in pressure causing the entrapped gas to form a cellular structure.

  • Publication number: 20150008608
    Abstract: A method and apparatus for injection molding a foamed product. A short shot of formable resin is injected into a cavity (124) defined by respective inner surfaces (134,136) of a plurality of molding plates (120,122) at an amount less than a volume of the cavity (124), the resin comprising a chemical foaming agent. The injected resin is allowed to foam for a predetermined period of time, during which the injected foamable resin foams and expands to substantially fill the cavity (124) and a portion of an outer surface face of the foamable resin contacts the respective inner surfaces (134,136) of the molding plates (120,122). Pressurized gas is injected into the cavity (124) after the predetermined time has elapsed to urge the skinned outer surface of the foamed resin against the inner surfaces (134,136) of the molding plates (120,122).

  • Patent number: 8926876
    Abstract: A method for making a shapeable article from poly(lactic acid) includes treating solid poly(lactic acid) that results in the solid poly(lactic acid) having a crystallinity of at least 20% by weight based on the weight of the solid poly(lactic acid) and a gas concentration of 6% to 16% by weight based on the weight of the solid poly(lactic acid); and heating the solid poly(lactic acid) having said minimum crystallinity and gas concentration to produce a cellular poly(lactic acid) article that is shapeable. The shapeable cellular poly(lactic acid) article is advantageous in that the article can be further shaped by heat and/or pressure (or vacuum), such as via thermoforming, into a variety of useful products.

  • Patent number: 8926874
    Abstract: The present invention relates to a porous manganese oxide-based lithium absorbent and a method for preparing the same. The method includes the steps of preparing a mixture by mixing a reactant for the synthesis of a lithium-manganese oxide precursor powder with an inorganic binder, molding the mixture, preparing a porous lithium-manganese oxide precursor molded body by heat-treating the molded mixture, and acid-treating the porous lithium-manganese oxide precursor molded body such that lithium ions of the porous lithium-manganese oxide precursor are exchanged with hydrogen ions, wherein pores are formed in the lithium-manganese oxide precursor molded body by gas generated in the heat treatment. The porous manganese oxide-based lithium adsorbent according to the present invention is easy to handle and has many more adsorption reaction sites compared to existing molded adsorbents, thus providing high lithium adsorption efficiency.

  • Publication number: 20140377523
    Abstract: The present invention generally relates to systems and methods for generating, processing, handling and forming plastic materials into an end product such as, but not limited to, consumables and packaging. The plastic materials are made into preforms or preform sheets, which in turn may be selectively masked to expose desired regions of the same for a saturation process, a heating process, or both. In addition, the various processes may be sufficiently controlled to obtain a desired micro-structure, and in turn obtain desired mechanical, structural, and aesthetic properties in the end product. By way of example, an embodiment of the present invention results in consumable, plastic cups that are lighter weight and more structurally robust less than conventional plastic cups. Further to one or more embodiments of the present invention, various systems for material handling may be utilized to efficiently, timely and cost effectively produce the preforms.

  • Patent number: 8871823
    Abstract: A first polymer (preferably in granular form) is exposed to a gas at a pressure higher than atmospheric pressure to introduce the gas into the polymer. This occurs at a temperature from the glass transition temperature to the melting temperature when the first polymer is crystalline or semi-crystalline in nature, or at a temperature below the glass transition temperature when the first polymer is amorphous in nature. Optionally, the gas-laden polymer may then be mixed with a second polymer. The polymer is then melted to produce a foamed article.
