Magnesium Photoengraving Plate

Fast, Neat slope, Good continuity, and Smooth edges. Compared to zinc photoengraving plate,magnesium photoengraving

plate has more advantages.Magnesium plate has a small specific gravity, light weight, fast heat conduction, heat transfer and heat dissipation, high surface hardness, easy demolding, and the etching of magnesium plate is hardly deformed during the hot stamping process. Magnesium plate etches clean and fast when using nitric acid. These properties make it ideal for use in numerous applications,foil hot stamping, cold foil stamping, embossing, debossing, engraving, crash printing, thermal dies, plaques, awards, letterpress printing and making engraving masters for rubber plates. The advancement in raw material preparation and the etching process have brought the quality of magnesium on par with heavier metals such as copper or brass.

Photoengraving Magnesium Plate Etching in Chemical Etching Machine

Etching Principle: The magnesium plate is to be corroded clamped on the turntable of the machine. Magnesium plate is also subjected to vertical impact of the corrosive liquid while making a rotary motion. The unexposured part of magnesium plate is corroded and dissolved, then a graphic magensium plate dies is made.
