The foaming for loss casting mold production or foaming Characteristic plastic material the lost mold which is formed with the material which catches

摘要

(57) Abstract It consists of the foaming or foaming Characteristic polymer or the copolymer which the polymer or the copolymer which does not give damage to character of the metal which does not change the feature of the polymer or the copolymer which the carbon of the plastic material and in order to make the oxidation of hydrogen possible, changing the oxidation property substantially the fact that you bet on dying foaming job are produced the case of cast of the melting metal, are combined before, in and after the foaming, substantially, casts, in addition is combined and was combined with the oxidizer which almost shows the same resolution temperature, is used for the production of the mold generally, the foaming for producing the lost casting mold or foaming Characteristic plasticMaterial. Production manner of the casting part due to the formation which uses the lost mold and these lost molds of this plastic material make.
