Hot stamping or hot stamping false analysis

Stamping or hot stamping false on this calendar and surface properties and electrochemical properties of the aluminum, hot stamping temperature and pressure, and other factors. Too much or surface (1) calendar surface spray powder from adhesive, light slurry additives, such as this will interfere with the adsorption of electrochemical aluminum and paper. Solution: to powder surface treatment or solution in printing process. (2) the electrochemical aluminum improper selection directly influence the bronzing fastness. Should be according to the size of the hot stamping area, by hot stamping material features comprehensive consider to choose what type of electrochemical aluminum. Domestic electrochemical aluminum ShenYong hot stamping material co. , LTD. Mainly Shanghai peacock brand series of production, imports of electrochemical aluminium kurtz (mainly Germany KURZ) PM and LK series, Japan A, K, H series, South Korea KOLON SP series. Electrochemical aluminum matching can be mainly refer to the following categories: ordinary products on the hot stamping ( The general ink) Electrochemical aluminum, 88 l, KURZ PM type; Smoke bag, cosmetics and so on the printing ink ( Including printed gold, silver) Hot stamping of electrochemical aluminum 882 type; Cigarette label, cosmetics packaging fine handwriting stamping electrochemical aluminum, 883, 884, PM288, etc; Suitable for OPP or PET combined with paper and have the UV printing ink, paper, glazed paper products such as stamping electrochemical aluminum type 884, K series, LK series, and SP series. Was not correctly grasp hot stamping equipment, and the matching of hot pressing time and temperature of the hot stamping, affecting the printing fastness and definition of the graphic outline. Because of the different devices, by hot stamping material, hot pressing time, hot stamping temperature are different. High speed press circle round machine faster, for example, stamping line contact, hot stamping temperature is higher than the round flatten or flat to flatten. Under normal circumstances, the press circle round hot stamping temperature in 190 ℃ ~ 220 ℃, round flatten around 130 ℃ ~ 150 ℃, flat flat in 100 ℃ ~ 120 ℃. Of course, hot pressing time, hot stamping temperature and production efficiency is largely restricted by electrochemical aluminum transfer performance.
