  • Patent number: 8709313
    Abstract: A method and apparatus for feeding a polyurethane mixture suitable to form a thermally insulating layer inside hollow bodies, such as hollow walls of a refrigerator cabinet, freezer, display counter or insulating panel. A polyurethane mixture resulting from chemically reactive components, supplied by a high-pressure mixing device, is injected into a cavity of a hollow body extending in a horizontal plain. The mixture is injected at a first flow-rate and a first injection speed, to be poured into a first deposition zone farthest from the injection point. Subsequently, the flow-rate and the injection speed of the polyurethane mixture are gradually reduced in a controlled manner, to be poured in successive deposition zones towards the injection point of the polyurethane mixture, along a distribution strip, allowing the injected mixture to spread out throughout the cavity of the hollow body along isometric expansion lines.

  • Patent number: 8703034
    Abstract: A process of making a tack-free gel is disclosed comprising the steps of providing a mold defining a mold cavity, the mold cavity comprising a plastic material; pouring or injecting a molten gel having a high molding temperature into the mold cavity; and forming the tack-free gel as a thin layer of plastic of the mold cavity is melted over the gel. The forming step further comprises cooling the gel from the molten state to a solidified state. The melting temperature of the plastic material is lower than the molding temperature of the gel; and the higher the temperature differential, the greater the melting of the plastic material and the thicker the layer of the plastic material on the surface of the gel. The mold may be formed of low-density polyethylene (LDPE).

    Abstract: An apparatus for molding a thermoplastic package part(s) to an end portion of a container body includes inner and outer mold elements between which a mold cavity per package part is formed. At least one of these mold elements is at least partly freely suspended. When one package part is molded with the mold elements, plastic melt is injected in a first number ?1 of points in the cavity, an island of plastic melt for each point is formed inside the cavity, and the distribution of the points causes a force center to pass through a surface defined by a parallel projection of each first number of islands on a plane orthogonal to a direction of the compression force, and when the first number >1, a second number of imaginary straight lines interconnecting a third number of parallel projections such that the surface is at its maximum.

    Abstract: An injection molding system is disclosed that utilizes a melt channel wherein at least a portion of the melt channel has a noncircular cross-section for balancing shear in a melt stream of moldable material that flows therethrough. The noncircular cross-section of the melt channel portion may be, for e.g., capsule-shaped, extended egg-shaped, oval, teardrop-shaped, or peanut-shaped. A flow splitter is also disclosed that is positioned offset from a central axis of an upstream melt channel to protrude between inlets of respective downstream melt channels, where the upstream melt channel splits into the downstream melt channels, to thereby create a narrower inlet into one of the downstream melt channels and a wider inlet into the other of the downstream melt channels.

  • Patent number: 8557160
    Abstract: A process, and related structure, uses conventional palletized compositions to form the elements of a non-textile fabric by coining a single pellet or briquette of a polymer into an individual element in a single forming step. The steps of the process generally include: a) positioning a pellet in or adjacent to a mold cavity, and b) forcing the pellet into contact with the mold surfaces of the mold cavity to plastically deform the pellet to the shape of the mold cavity. The forcing step preferably uses an energy and speed where the pellet superplastically deforms to substantially fill the mold cavity. This process is repeated with the elements being formed in the appropriate order to form a non-textile fabric. The elements thus formed can have a variety of shapes, and can form base units for the formation of the non-textile fabric of two, three or more elements.
