    Abstract: A material with a cellular structure is formed from melt-stretched granules. Granules compressed between stretching surfaces are melted to form viscous molten layers attaching ends of the granules to the surfaces. Melted central portions of the granules are stretched by moving the surfaces away from one another. A cellular structure is thus formed between the molten layers, both of which are solidified to form a solid material. A cellular material may also be formed by melting a melt-stretchable material to form a sheet of viscous molten mass formed of opposite surface layers connected by a central portion, stretching the central portion by pulling the surface layers away from one another to generate air cells randomly distributed throughout the central portion, and solidifying the cellular core and the skins formed from the central portion and the surface layers.

    Abstract: A method for producing a skin-covered foamed molded article including blow-molding a parison in a mold cavity to form a skin consisting of a hollow molded body, in which the parison is in a softened state by extruding a molten thermoplastic resin, filling expanded beads in the hollow molded body, and heating and fusion bonding the beads by supplying steam via a steam supply pipe inserted into the hollow molded body. The parison is in contact with a protruding portion, formed by protrusion from an inner surface of the mold cavity to an inside of the cavity, forming a recessed portion having a shape corresponding to the protruding portion in the inward direction of the hollow molded body. A steam hole is formed in the recessed portion, a steam supply pipe is inserted into the body, and the expanded beads are heated and fusion bonded by supplying steam.

  • Patent number: 8470217
    Abstract: After heating the expandable resin beads to sealing temperature of expandable resin beads in the presence of heated steam, foam cells are sealed and cooled while controlling the foaming amount. The foaming amount is controlled by pressure control on the expandable resin beads in the mold. Mutually adjacent foam cells are softened, fused, and bonded on contact faces, and thereby a foamed molding is manufactured. This foamed molding is characterized by three-dimensional permeable pores of volume porosity of 10 to 40% among foam cells, having bending limit strength of at least 10N. Without using adhesive resin, a foamed molding having enough strength and desired porous structure is obtained.

    Abstract: A method for manufacturing a pallet includes the following steps: (a) preparing a bottom case and a top cover respectively; (b) positioning the bottom case and top cover into a mould of an EPS foams molding machine, closing the mould and filling the mould cavity with EPS beads; (c) heating to make the EPS beads expand to form an inner core which is fused with the bottom case or top cover and then doing a cooling process; (d) opening the mould, positioning the top cover or bottom case onto the bottom case or top cover and closing the mould, heating to make the EPS beads expand again to be fused with the top cover or bottom case, and then doing a cooling process; and (e) demolding to produce a pallet. The outer casing and inner core of the pallet has good bond strength, thereby ensuring the quality of pallet.

    Abstract: A molded article is made by first providing a starting material comprised of a support web and a layer of expandable polymer particles on the support web. This starting material is fitted as several layers into a generally closed cavity of a mold or shaping shell so as to only partially fill the cavity. Then energy, for instance microwave radiation, is applied to the starting material in the cavity so as to expand or foam the polymer particles such that the starting material generally fills the cavity.
