By Compression In A Closed Mold Cavity Patents (Class 264/77)
  • Patent number: 10351799
    Abstract: A method of forming a layered candle assembly includes positioning a candle core in a form. A layer of powdered wax is loaded into the form. The powdered wax layer has an outer region and an inner region. Mechanical force is applied to compress the outer region of the powdered wax layer and form an upper interface surface that is substantially non-horizontal. The outer perimeter of the interface surface is visible to an observer in the finished candle assembly. A liquefied fuel substance is poured over the top of the powdered wax layer to form a layer of solid wax. A wick may be added to at a desirable stage in the method of forming the layered candle assembly. The powdered wax and solid wax layers may each have a color or a combination of colors and/or a scent component or a combination of scent components.

  • Patent number: 9090509
    Abstract: The present invention relates to panels or slabs formed by stone agglomerate for the manufacture of which an organic binder containing an ingredient of a plant origin is used. The panels or slabs object of the invention are formed from stone materials or the like, granulated and subsequently agglomerated by means of a binder, specifically an organic resin containing one or more polyols of a plant origin. Furthermore, by means of using this binder together with materials from waste and used and/or recycled products, a material with good features and with a very high content of recycled material or material of a renewable origin can be obtained. The manufactured panel or slab containing a resin part of a plant origin of the present invention is particularly suitable for its use indoors as a kitchen counter, a bathroom counter, or any work surface, as well as for its use as flooring or sidings.

  • Patent number: 5262103
    Abstract: Disclosed is a cold molding process for the production of a unitary article from a plurality of plastic particles. The process may be conducted without the addition of heat. A plurality of homogeneous or heterogeneous plastic particles are introduced into a mold, softened by exposure to a softening agent, and thereafter compressed to form the unitary article. Preferred softening agents comprise an organic component and an aqueous component. One preferred softening agent-plastic combination comprises aqueous methylethylketone and polystyrene.

  • Patent number: 5244942
    Abstract: The invention concerns a homogenous, in particular multicolored plastic sheet or panel, based on ethylene vinyl acetate copolymer (EVA) as binder with a filler content of 30 to 80 wt. % and a process for producing it. In other embodiments the binder contains, in addition to the 70 to 85 wt. % of EVA, polypropylenes to improve the processability (tendency to adhere), EPDM to improve the flexibility, and polyethylenes to reduce the tendency to soiling. In the process described, several additives, each consisting of a binder containing at least some ethylene vinyl acetate copolymer, up to 80 wt. % of fillers and up to 5 wt. % of pigments, are mixed, plasticized and granulated or comminuted to form granules or chips of assorted colours which are mixed and, possibly after other processing operations, pressed to form the plastic web or plates.

  • Patent number: 5213854
    Abstract: The invention discloses a method of making articles and items with one or more surfaces with a solid stone-like appearance by filling a space with two materials, one of which is a finely cut-up material and the other of which is a filler. The method includes steps which eliminate the apparent thickness of the transparent medium through which the finely cut-up material is seen, thus enhancing the stone-like appearance.

  • Patent number: 5154868
    Abstract: A method of manufacturing a randomly patterned floor covering having contrastingly-colored zones from a preform of rubber in which the preform is cut in pieces, each of which are molded into a blank having projections extending from a top side of the blank in relief-like fashion, solidified by vulcanization and then machined by cutting only in the region of the projections. The rubber forming the contrastingly-colored zones is mixed with contrastingly-colored particles in an amount of at least ten percent by weight. These particles are substantially free of flat surfaces and are in, at least, an advanced state of vulcanization. The particles located in the projections extending from the top side of the blank are exposed during the cutting step.

  • Patent number: 5078933
    Abstract: A grained and foamed plastic article is fabricated by forming foamed plastic grains which are then covered with coating layers with a color different from that of the grains. The coated grains are then formed into a desired shape by heating them under pressure. The grained pattern formed thereby includes clear grain boundary lines which enhance the esthetic effect of the formed article.
