Bronzing machine manufacturers tell you that these problems are related to the surface characteristics of the printing, anodized properties, hot stamping temperature and pressure and other factors. The following is hot Bronzing machine factory tutor you when these failures, how to make the corresponding solution.
(1) printing surface dusting too much, printing ink is not dry or the surface contains adhesive, light oil and other additives, will hinder the absorption of aluminum and paper. Can be printed on the surface of the powder treatment or in the printing process.
(2) anodized aluminum improper selection will directly affect the stamping fastness. Should be based on the size of the bronzing area, the characteristics of hot stamping materials to consider which model of anodized aluminum. There are many types of anodized materials on the market, and all kinds of models have different material substrate and its most suitable hot stamping range, they are mainly used in the process of adhesion and peeling degree to distinguish. When the operator chose the fastness and tightness of the anodized material for hot stamping, hot stamping patterns on the cigarette package will appear false and gold.
(3) did not correctly grasp the gold stamping equipment, stamping time, stamping temperature between the match, affect stamping fastness and text outline clarity. As a result of equipment, hot stamping materials are different, hot stamping time, hot stamping temperature are not the same. For example, high speed rotary machine speed, stamping line contact, hot stamping temperature will be higher than round or flat. In general, the rotary stamping temperature of 190% ~ 220℃, about 130℃ ~ 150℃, about 100℃ ~ 120℃.
Of course, hot stamping time, hot stamping temperature and production efficiency are greatly affected by the transfer performance of anodized aluminum. Also pay attention to check whether the pressure is balanced, part of the text and text on the hot stamping should also check whether there is damage.
