A core molding apparatus includes: a kneading tank configured to knead a raw material for a core; a raw material supply unit configured to supply the raw material to the kneading tank; a mold configured to contain a kneaded material made of the raw material kneaded in the kneading tank and to mold the core; a piston configured to inject the kneaded material contained in the kneading tank into the mold; and a control unit configured to control an amount of supply of the raw material from the raw material supply unit to the kneading tank.

A foam molding apparatus and a foam molding method thereby are proposed. The foam molding apparatus includes a foaming agent supply unit configured to supply a foaming agent, a molten resin supply unit configured to supply molten resin, a fixed mixing unit configured to produce a foaming resin-critical solution by mixing a foaming agent supplied from the foaming agent supply unit and molten resin supplied from the molten resin supply unit through a rod-shaped body, and a molding unit configured to mold a foam molding product using the foaming resin-critical solution supplied from the fixed mixing unit. Accordingly, it is possible to produce a foaming resin-critical solution by uniformly mixing a large amount of high-viscosity gel-state molten resin and a high-pressure compressed and low-viscosity foaming agent, using high-strength multiple channels.

A fire retardant molding contains a thermoplastic compound and an inorganic flameproof agent that is mixed with the thermoplastic compound and which acts by separating from water, having a proportion in the range of 10 wt % to 90 wt %. The fire retardant molding is produced by mixing the thermoplastic material with an inorganic flame-proofing agent, the flame-proofing agent having a proportion in the range of 20 wt % to 80 wt %, and by outputting the compound obtained by mixing, in particular as a flat product. The fire retardant molding is advantageously used, for example, in or on land-based vehicles, water-based vehicles, aircraft and buildings.
