Let's have a detailed understanding of the cold ironing process together. With the rapid development of cold stamping technology, it has occupied an important position in the field of electrochemical aluminum printing. As a part of product packaging, unique and beautiful printing and effects are deeply loved by merchants and customers. It combines the advantages of traditional printing and lamination technology, with simple operation. Adding some auxiliary equipment to the printing machine used in the printing factory can be used for cold stamping printing, creating a unique effect, not only reducing production costs, but also increasing the added value of the product. The cold stamping uses special anodized aluminum, whose back is not coated with glue, and Adhesive is directly applied to the position requiring decoration during printing. Using a new technology of cold pressing to transfer electrochemical aluminum foil. Cold stamping technology solves the difficult process problems in hot stamping printing, avoids environmental pollution during the production of metal printing plates, and can also save a lot of energy. The electrochemical aluminum foil, working principle and process flow of cold stamping are different from the traditional hot stamping. The back of the electrochemical aluminum foil used in the traditional hot stamping process is pre coated with Hot-melt adhesive. When stamping, the Adhesive is melted by the pressure of the hot roller to realize the transfer of aluminum foil.
