(Summary description) Supercritical foaming molding is a physical foaming molding technology, at the same time is also a kind of microcellular foaming molding technology, it is in the injection molding, extrusion and blowing molding process, first the supercritical state of other gases such as carbon dioxide or nitrogen injection to the special plasticizing device, make the gas and molten material after fully mixing/diffusion, single-phase hybrid sol formation, and then the sol guide mold cavity or extrusion die mould, make the sol produces pressure drop, so that the gas evolution formed a large amount of bubbles nuclear; In the subsequent cooling molding process, the bubble core inside the sol is constantly growing and forming, and finally the microporous foaming plastic products are obtained.
