The production process of electroforming signs is: printing plate, electroplating, peeling and glueing
1. Exposure: The electroforming master is made of a stainless steel plate that is easy to peel off after plating. After degreasing and cleaning, it is printed with a photoimageable electroplating resistant photosensitive adhesive. After the exposing plate is developed, a post-exposure treatment is carried out to increase the resistance of the photosensitive adhesive. Plating.
2. Electroforming: Clamp the processed stainless steel plate with image with a special fixture, and put it into the rapid electroforming nickel tank for electroforming. The electroforming time and current size 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 a transfer film to completely peel off the electroplated text and pattern.
4. Gluing: There are two methods: one is to use the screen printing method to screen print the self-adhesive on the back of the electroformed characters and patterns, and you can use it after drying; the other is to print the self-adhesive on the transfer paper first After drying, paste the electroformed characters and patterns on the transfer film onto the adhesive film, and transfer the self-adhesive film to the back of the electroformed characters and patterns after pressing.
