    摘要: PROBLEM TO BE SOLVED: To disclose a process of fabricating a cast foam product, an intermediate foam product, and a cast foam product.SOLUTION: A process includes positioning a foamable component and alloying particles within a die and injecting steam into the die and expanding the foamable component to form a foamed component. The foamable component includes one or more of polystyrene and polymethylmethacrylate. The intermediate foam product includes the alloying particles, the foamable component, and the steam. A cast foam product includes a distribution of the alloying particles and the foamed component including one or more of polystyrene and polymethylmethacrylate, with the alloying particles being physically bound by the foamed component.

    摘要: PROBLEM TO BE SOLVED: To control the traceability of a molding by using the piston of a raw material packing machine. SOLUTION: The foamed resin molding raw materia packing machine has a sleeve 2 in which an opening 21 connected to a cavity 93 formed between a fixed mold 90 and a movable mold 91 is formed, an inflow part 31 for supplying the raw material into the cavity, and the piston 5 which moves forward/backward between an advance position closing the opening 21 of the sleeve 2 and a retreat position allowing the inflow of the raw material. With regard to the piston 5, a plunger 51 with an index formed is set at the head end, and an expression 25 corresponding to the index is formed in the peripheral part of the opening 21 of the sleeve 2. The piston 5 is installed to be able to rotate with the longitudinal direction of the piston 5 made an axis to make the index of the plunger 51 be turned to the expression 25.
