　　In daily life, the application of signs is very common. Some are used for advertising, some are used to convey information, and some are used for warning. There are many types of signs, including ordinary metal signs, electroformed signs, and digital signs.

　　Scope of application of electroformed signs: The materials of electroformed signs include copper, nickel, and gold. The surface is bright, the periphery is smooth, the graphics are accurate, and the weather resistance is particularly good. Therefore, electroformed signs are high-end signs. The production process of electroformed signs is simple and the price is not high. So people say that electroformed signs are low-priced and high-end signs. In addition, it uses strong self-adhesive paste, which is very convenient to use and therefore has a wide range of applications. Especially suitable for making nameplates and decorative panels for small and medium-sized light industrial products such as metal surfaces, spray painted surfaces, plastic, wood, leather, etc. The combination of electroforming technology with processes such as refraction, three-dimensional, and crystal glue can achieve unique effects.

　　1. Exposure: The electroforming master plate is made of stainless steel plate, which is easy to peel off after electroplating. After degreasing and washing, use a photoimageable electroplated photosensitive offset brush. After developing the exposure plate, perform post exposure processing to increase the resistance of the photosensitive adhesive. Electroplating.

　　2. Electroforming: Use a specialized fixture to clamp the processed stainless steel plate with images and place it into a rapid electroforming nickel groove for electroforming. The duration and current of electroforming depend on the area and thickness of the object to be cast.

　　3. Peeling: Wash and dry the cast stainless steel plate, and then use transfer film to completely peel off the electroplated text and patterns.

　　4. Gluing: There are two methods: one is to use screen printing to print the adhesive on the back of electroformed text and patterns, and then use it after drying; The second is to first dry the adhesive on the transfer paper, then paste the electroformed text and patterns on the transfer film onto the adhesive film, press it tightly, and transfer the adhesive film to the back of the electroformed text and patterns
