| 摘要 | PURPOSE:To form a model of a metallic mold for precision casting having a good surface condition with eacy working of the model without the distortion thereof in the manufacture of said model by working a rigid urethane resin to the model of the casting mold allowing for shrinkage allowance of a casting material. CONSTITUTION:The rigid urethane resin has suitable hardness, excellent workability and uniform material density and is therefore unaffected by a temp. change and humidity and surface finish is smooth. The satisfactory model having the good surface finish without the distortion is thus obtd. if the model of the casting mold allowing for the shrinkage allowance of the casting material is worked and manufactured of such rigid urethane resin. | ||||||
