Title:
金属製品の電鋳による製造方法
Document Type and Number:
Japanese Patent JP6993108
Kind Code:
B2
Abstract:
To produce a metal product by performing electroforming only once, without a need for forming an electroconductive film or for carrying out conductive processing on the surface of a vanishing material.SOLUTION: First, a liquid mixture 14 of liquid rubber and a liquid hardener is poured into a container 13 containing a model 12 disposed thereinside to bury the model therein, and subsequently the liquid mixture is hardened to produce a rubber mold 16. Thereafter, the model is extracted from the rubber mold and an electroconductive vanishing material 18 is poured into a cavity 16a formed in the rubber mold and is hardened to produce an electroconductive vanishing model 19. Subsequently, the electroconductive vanishing model extracted from the rubber mold and electroforming metal are immersed in the electrolytic liquid present in an electrolytic tank, and an electric current is supplied to them to form a metal layer on the surface of the electroconductive vanishing model by electrodeposition. Further, the electroconductive vanishing model with a metal layer formed on the surface thereof is taken out of the electrolytic tank and is heated to cause the electroconductive vanishing model to vanish, thereby producing a metal product comprising a metal layer.SELECTED DRAWING: Figure 1
