Description

Manufacturing method of figure relief by electric casting

The present invention relates to a manufacturing method of the character relief by electroforming, and more particularly, it is possible to industrially mass-produce the character relief by artistic techniques, thereby enabling the mass supply of works with molding beauty at low cost. .

Relief statues celebrate the achievements and contributions of gods, saints, generations of kings, great men, generals or ancestors, scholars, founders, seniors, and fellows by engraving the faces of bronze, stone, plaster, wood, etc. It is intended to be an educational example for future generations.

However, these sculptures cannot be portrayed as they are not sculptors or master craftsmen, making them long and expensive.

Therefore, if you replace it as a general photograph, it is insufficient to give an impression to the viewer who does not have a three-dimensional effect.

The present invention provides a first process for producing rubber engravings, a second process for electroforming, a third process for coloring and gold plating, and a production and mounting of a frame to enable the manufacture and production of such a statue relief. It is completed as a four-step process, and this figure is used as a relief for the walls of homes and offices, the cornerstones of large museums and libraries, the gravestones and statues of graveyards, and the crests of each ossuary. To do it.
