Electroformed signs are not only simple to produce but also minimally polluting the environment. Signs are widely used in daily life. Some are used for advertising, others for informational purposes, and others for warnings.

There are many types of signs, including ordinary metal signs, electroformed signs, and digital signs. The following are the characteristics of metal signs:

Electroformed signs are characterized by the absence of a substrate. Traditionally, signs have been manufactured by placing the text and images onto a substrate. Different heights, electroformed molds, varying reflectivity (glossy or matte), and colors are used to distinguish the sign from the substrate, thereby highlighting the main body. Electroforming is a metalworking technique used in the production of electroformed molds. Common products, such as screws and mobile phone metal casings, undergo electroforming. The electroforming process, as we know it, involves depositing metal ions onto the surface of a core mold through electrolysis, enabling the manufacture of metal parts and replicas. Electroplating is often confused with electroforming. While the two processes share similar principles, electroforming requires the core mold to be separated from the electroformed layer, while electroplating does the opposite.

Electroforming can produce a mold cavity based on a template. If the sample is accurately produced, the resulting core will rarely shrink, achieving a precision of less than 1. Therefore, precision finishes as fine as fingerprint marks, hairlines, or even diamond mirror finishes can be achieved in a single pass, without the need for polishing or plating. Diamond, brushed, leather-grained patterns, as well as complex, high-gloss mirror finishes, can also be produced.
