Porous electroformed shell for patterning and manufacturing method thereof

Abstract

Disclosed are a porous electroformed shell for forming a grain pattern and a manufacturing method thereof. The method includes the step of causing an epoxy mandrel to be conductive by formation of a conductive thin film thereon; transferring a non-conductive masking pattern on the conductive thin film by using a masking film; generating and growing a fine pore at the position of the non-conductive masking pattern through electroforming; and demolding an electrodeposited layer having the fine pore from the epoxy mandrel, Through the disclosed method, precise control, both as a whole or in part, on a diameter, a formation position, and a density of a fine pore can be simply, economically, and efficiently can be carried out according to various curved shapes of the electroformed shell. Accordingly, in forming the surface of a high-quality surface skin material or a plastic molded product with a predetermined pattern, when the fine pore is used as a decompression suction hole or an air vent, a predetermined pattern can be efficiently and economically obtained in such a manner that it has a regular position, a regular directionality, sharp radii, and minimized deformation.
