Nigeria costumer order 30pcs magnesium etching plates

In June, HOTSALES, 30pcs magnesium plates are packed for delivering to our customer in Nigeria .High quality magnesium plates with good packing.

The demand for magnesium plates in the printing field is mainly concentrated in the fields of bronzing and embossing, which also called magnesium alloy etching plates. The corrosion process of magnesium plate is divided into several steps, such as printing, opening, pickling and alkali cleaning. The processed product can be installed on the hot stamping machine and used directly.

The advantages of magnesium plates compared with zinc plates and copper plates are: 

(1) Plate making time: The plate making process of bronzing plate is generally similar, and the main difference is reflected in the etching time. When the etching pattern and the required etching depth are the same, the magnesium plate takes time. 5min, zinc plate takes 25min, copper plate exceeds 30min; 

(2) Hardness: Hardness is the main technical parameter for measuring bronzing plate. When the temperature is below 50℃, the Brinell hardness of magnesium plate is 70, zinc plate is 60, and copper plate is 95. When the plate is heated to At 100°C, the hardness of magnesium plate is 65, that of zinc plate is 30, and that of copper plate is 88. It can be seen that when the temperature required for bronzing is reached, the hardness of the magnesium plate changes the least. This directly affects the number of printings. Under the same conditions, the printing volume of magnesium plate and copper plate is more than 200,000 times, while that of zinc plate is less than 50,000 times; 

(3) Hot stamping effect: After the magnesium alloy etching plate is made, the slope is suitable, The edge is sharp, the hardness is high, and the heating and cooling are fast during the hot stamping production process. The surface of the substrate after hot stamping is very bright, and the effect is the same as that of the copper plate, far exceeding that of the zinc plate; 

(4) Cost: In the same area and the same thickness , Under the same requirements, the cost of using magnesium plate is 30% lower than that of zinc plate, and 70% lower than that of copper plate. In the process of bronzing production, the production cost of magnesium plate is 10% lower than that of zinc plate and copper plate. 

(5) Environmental protection: Zinc plate and copper plate produce a large amount of waste liquid rich in heavy metal ions during the plate making process, which cannot be recycled and cause serious environmental pollution. Magnesium is a recognized light metal, which is harmless to the human body and the environment. Rich in crust and seawater, it is a resource with great market potential.
