The superiority of Photoengraving magnesium plate was recognized since 1970s. Later, along with the vigorous development of the printing and packaging industry, Photoengraving magnesium plate as high-end hot stamping dies has been popular and widely applied. There are several advantages for the photoengraving magnesium plates:
1) The specific gravity of magnesium plate is small. and It also has the advantage of light weight, fast heat conduction, good heat transfer and heat dissipation, better surface hardness, easy to release; and almost no deformation, high resistance to printing rate; the etching process is fast, neat slope, good continuity, smooth edge.
2)In the paper product packaging industry, etching magnesium plate is used as hot stamping dies and embossing blocks. The same size of dies, magnesium plate is easy and fast to transport, install and glue the plate. Photoengraving magnesium plate has a small heat capacity ratio, better stamping effect, bright gold letters, fine and lustrous patterns.
3) The stamping speed of magnesium plate is much faster than copper and zinc plate, and the resistance rate is 20% higher than copper plate, which can effectively improve the processing speed and save labor cost.
4) In the wine packaging industry, photoengraving magnesium plate can be used for hot foil stamping and embossing dies. The good resistance to printing rate and heat transfer rate can greatly improve the efficiency of work, making the magnesium plate for etching is popular.
