Problems solved by technology

High-quality hot stamping plate is the first condition to ensure high-quality hot stamping effect. In the field of printing machinery, hot stamping plate is used more and more widely as an important part of the hot stamping process. In the existing round pressing and round hot stamping equipment, the hot stamping plate is a whole or It is made of a single piece and combined with a hot stamping roller for hot stamping printing. Since this kind of hot stamping plate is made of copper and the copper is soft, it is particularly easy to be crushed or damaged during the hot stamping process. At present, the hot stamping plate mainly has the following...

Abstract

The invention discloses a production technology of a fine bronzing plate with high precision and hardness. The production technology comprises the following steps : (1) loading materials; (2) chemical oil removal; (3) recycling washing; (4) electrolytic activation; (5) double cleaning; (6) nickel plating: carrying out chemical nickel plating by using a plating liquid containing 28 g / L nickel sulfate, 30 g / L sodium hypophosphite, 18 mL / L lactic acid (W = 85%), 13 g / L sodium acetate, 8 mg / L potassium iodate and purified water, adjusting the pH value of the plating liquid to 4.6-4.9, stirring at 85-91 DEG C for 3-5 min; (7) double cleaning; (8) drying; and (9) rolling. The invention employs electrolytic activation in advance and nickel preplating to substantially enhance firm combination degree of a nickel coating and a copper base and prolong service life of the bronzing plate.

Description

technical field [0001] The invention relates to the technical field of bronzing plate electroplating technology, in particular to a production process of high-precision and fine-hardness bronzing plate. Background technique [0002] With the improvement of people's living standards, product packaging has higher and higher requirements. In order to improve the exquisiteness of packaging, people use many different pre-press design, printing reproduction and post-press processing techniques, among which bronzing is the most commonly used process. , the bronzing process is based on the principle of heat transfer. Hot stamping heats the metal printing plate, applies foil, and embosses bright text or patterns on the tipping paper to form a special metal effect, so as to achieve a colorful and beautiful effect. . With the improvement of the grades of tobacco, wine and gift packaging, bronzing technology is widely used. High-quality hot stamping plate is the first condition to ens...
