Zinc alloy, as a metallic material, possesses advantages such as low density, high strength, good corrosion resistance, and ease of processing and shaping, making it an ideal choice for signage production. The manufacturing processes for zinc alloy signs are diverse, including die casting, stamping, engraving, electroplating, and painting. Signs of various shapes, sizes, and colors can be produced according to different needs and design requirements.
The production of zinc alloy labels primarily relies on metal forming and surface treatment technologies. Die casting involves injecting molten zinc alloy into a mold under high pressure, and after cooling, a sign of the desired shape is obtained. Stamping uses a punch press and molds to press zinc alloy sheets, forming the shape and text of the sign. Engraving uses mechanical or laser engraving to carve text and patterns onto the zinc alloy surface. Electroplating and painting processes are used to enhance the corrosion resistance and aesthetics of the signs.
