2020 Chinese Spring Festival Holiday start from Jan 20th to Jan 31st. During the holiday period, please send us email if there is request of magnesium plate, there would be sales contact you once seeing your inquiry.

There are many advantages Of Magnesium Photoengraving Plate as etched metal material,it become popular now in printing industry.

1. Etching Time: it takes 5 minutes for magnesium plate, 25 minutes for zinc plate, and 30 minutes for copper plate with the same pattern and the same required etching depth.
2. Hardness:  Hardness is the main technical parameter to measure the hot stamping die. Below 50 ° C, the hardness of the magnesium plate is 92, the zinc plate 36, and the copper plate 96. When the plate is heated to 100 ° C, the hardness of the magnesium plate is 90, the zinc plate 30, and the copper plate 88. It can be seen that when the temperature required for bronzing is reached, the hardness change of the magnesium plate is minimal. This directly affects the printing quantity. Under the same conditions, the printing quantity of magnesium and copper plates is more than 200,000 times, and that of zinc plate is less than 50,000 times.
3. Cost of Production: With the same area, thickness and 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 hot stamping production process, the production cost of magnesium plate is still 10% lower than that of zinc plate and copper plate.
4. Etching Pattern Result:  magnesium alloy etched plate has the proper slope, sharp edges, and high hardness, and it is heated and cooled quickly during the ironing production process. The surface of the substrate after hot stamping is very bright, and has the same effect as the copper plate, far exceeding the zinc plate.
