    • 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.
    • 公开了一种用于形成颗粒图案的多孔电铸壳及其制造方法。 该方法包括通过在其上形成导电薄膜使环氧心轴导电的步骤; 通过使用掩模膜在导电薄膜上转印非导电掩模图案; 通过电铸在非导电掩模图案的位置产生和生长细孔; 通过所公开的方法,可以简单地,经济上精确地控制直径,形成位置和细孔密度,整体上或部分地精确地控制了细孔的电沉积层。 并且可以根据电铸外壳的各种弯曲形状有效地进行。 因此,在形成具有规定图案的高品质表皮材料或塑料成型体的表面时,当细孔用作减压吸孔或排气孔时,可以有效地和经济地获得预定图案 这种方式使其具有规则位置,规则方向性,锐利的半径和最小的变形。
