New revolution in the bronzing industry

1. Alternative introduction

Letterpress printing usually adopts copper plate and zinc plate, which is made by engraving or etching to make the required layout, but the quality of engraving layout is still different from that of etching plate. Therefore, the quality of the layout made by pre-coating photosensitive and etching process is good. , And high efficiency. Because magnesium alloy has the unique advantages of light weight, non-deformation, high specific strength, good shock absorption, etc., as well as more excellent deep corrosion and easy-to-control accuracy than copper and zinc, it is easier to achieve accurate corrosion plate making The layout is smoother than the shoulders of the layout made of copper and zinc materials, the slope is even, and there is no layer and bottom damage, which makes the printing layout more clear and perfect. At the same time, etching plate making can also be used in fields such as corrosion mold making, and will become the main material in the fields of printing corrosion plate making and corrosion mold making. The resources of magnesium in our country are quite rich, and the resources of magnesium are unlimited. Therefore, the use of magnesium alloy materials instead of copper and zinc materials for plate making will have more advantages.

2. Product introduction

High-quality bronzing plate is the primary factor to ensure bronzing quality. The material is usually copper plate or zinc plate. The two-magnesium plate has fine material, and the surface finish and heat transfer effect are better than those of copper plate and zinc plate. The use of high-quality magnesium plate can improve the glossiness and outline definition of bronzing graphics.

Magnesium alloy has many advantages such as low density (only 1.75), high specific strength and specific stiffness, fast heat dissipation, damping and shock absorption, environmental protection and easy recycling. Today, when resources are exhausted, abundant magnesium is a substitute for steel, aluminum, and copper. , Zinc and other best green metal materials.

In view of the many advantages of magnesium alloys, applying magnesium alloys to the bronzing industry will give greater play to its advantages. Compared with copper plate and zinc plate, magnesium plate has obvious advantages:

1)Long service life: 20,000 to 30,000 sheets are printed on the zinc plate, about 10 sheets are printed on the copper plate, and the magnesium plate is harder than the copper and zinc plates after heating at 150°, and can print more than 100,000 copies;

2)High production efficiency: Magnesium plate has small heat capacity and fast heat dissipation, which can greatly improve the production efficiency of hot stamping and printing, and can be used in high-speed hot stamping machines;

3)the product is beautiful: magnesium plate hot stamping product, the edge of the pattern is clear and shiny. Deep press refraction pattern is more refined.

European and American national teams have higher quality requirements for printed materials, pay attention to environmental protection costs, and labor is relatively high, so 95% of the bronzing and etching metal plates used are mostly magnesium plates.

4)Depth of etching magnesium plate: 0.5-5mm deep
