Abstract: A method for manufacturing a reconstituted stone raw material by using a molten slag includes: controlling a temperature of the molten slag at 1400° C.-1500° C., and performing a cast-molding process on the molten slag; and maintaining the cast-molded slag at a temperature of 800° C.-1000° C. for 1-5 hours in a non-reducing atmosphere, and then gradually cooling the cast-molded slag to a room temperature within 2-5 hours to obtain the reconstituted stone raw material. An energy-saving and efficient method for comprehensively utilizing the blast furnace slag is provided. The produced reconstituted stone raw material has such characteristics as stable color quality, abrasion resistance, pressure resistance, strong adhesiveness, low coefficient of expansion and low shrinkage ratio.

Abstract: Three-dimensional fabrication resources are improved by adding networking capabilities to three-dimensional printers and providing a variety of tools for networked use of three-dimensional printers. Web-based servers or the like can provide a single point of access for remote users to manage access to distributed content on one hand, and to manage use of distributed fabrication resources on the other.

Abstract: An injection moulding process for making a completely recyclable, multilayered article which contains: i) a rigid layer formed of a thermoplastic polymer and ii) a foamed skin layer formed of a thermoplastic polymer compatible with the material of the rigid layer, by injection moulding of the rigid layer into a mould composed of two sides, lifting one side of the mould, or change one side of the mould to obtain a small gap of between 3 to 4 mm between the rigid layer and the side of the mould lifted or changed and injecting the foamed skin layer into the gap formed in step b).

Abstract: A mold apparatus and method for forming a shaped laminate in one step are provided where the laminate includes a cladding layer and a foam backing layer. The apparatus includes a male mold half matable to a female mold half that define a mold cavity. An inlet is mounted on the mold apparatus for introducing foamable materials into the mold cavity. Edge folding members, carried by one of the mold halves, movable from a retracted position to an extended position, fold the cladding layer over at least part of the edge of the foam backing layer. Trim blades are located adjacent to the edge folding members movable from a retracted position adjacent the cavity to an extended position engaging the other mold half to sever the cladding layer to define the finished shape of the laminate.

Abstract: An apparatus for producing and cooling polymer pellets. Hot pellets cut from a die plate extruder are impelled through air and quickly enveloped in a stream of cooling liquid. The stream is then directed to flow in a first horizontal and vertically descending path, and deflected and inverted into one or more succeeding horizontal and vertically descending paths forming a cascade array, until the pellets are cooled to a predetermined temperature.
