摘要： Disclosed is a coating material for a coating layer of an injection mold, the coating material including 100 parts by weight of a resin composition and about 30 to 40 parts by weight of a curing agent. The resin composition includes an amount of about 40 to 50 wt % of a first acrylic resin, an amount of about 5 to 15 wt % of a second acrylic resin having a weight average molecular weight less than a weight average molecular weight of the first acrylic resin, an amount of about 10 to 15 wt % of a carbon component, an amount of about 0.5 to 2 wt % of a matting agent, an amount of about 0.1 to 0.3 wt % of a catalyst and an amount of about 20 to 35 wt % of a solvent, all the wt % are based on the total weight of the resin composition.

摘要： 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.

摘要： Disclosed are a porous electroformed shell for forming a grain pattern and a manufacturing method thereof. The method includes the step of implanting a fiber into a patterned surface of a negative-type silicone cast; applying, laminating, and curing an epoxy resin on the patterned surface of the negative-type silicone cast, and transferring the fiber from the negative-type silicone cast to an epoxy mandrel during demolding of the epoxy mandrel; forming a conductive thin film on the patterned surface of the epoxy mandrel, and causing the patterned surface to be conductive; removing the fiber having the conductive thin film from a surface of the epoxy mandrel; forming an electrodeposited layer by electrodepositing an electroforming metal on the conductive thin film while generating and growing a fine pore at a position of a hole due to the removal of the fiber; and demolding the electrodeposited layer having the fine pore from the epoxy mandrel. Through the disclosed method, precise control on a diameter and distribution of a fine pore can be simply and efficiently can be carried out.
