In April, Belgium customer order 50pcs magnesium plates

In March, HOTSALES, 50pcs magnesium plates are packed for delivering to our customer in Belgium.High quality magnesium plates with good packing.

Pre-coated photoresist magnesium version is also called magnesium version. At present, there is a wide range of demand for it in the printing field, and the demand is increasing sharply. In fact, magnesium alloy sheets have been widely used in the printing field as early as 40 years ago, mainly in Europe and the United States, and domestic copper plates and zinc plates have always been the main ones. prices remain high. However, the damage to the environment by the copper plate and the zinc plate is very serious. At the same time, the performance of the copper plate and the zinc plate is not as good as that of the magnesium plate. Therefore, with the progress of domestic technology, the magnesium plate has gradually appeared in the market, and more and more copper plate and zinc plate are covered by the magnesium plate. Instead, if all these copper and zinc plates are replaced with magnesium plates, the annual demand for magnesium plates will be more than 7,000 tons.

The demand for magnesium plates in the printing field is mainly concentrated in the fields of bronzing and embossing, that is, 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.

Compared with the zinc plate and the copper plate, its advantages are: (1) Plate making time: The plate making process of the 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 5min. (2) Hardness: hardness is the main technical parameter to measure the hot stamping plate. When the temperature is below 50 °C, the Brinell hardness of the magnesium plate is 70, the zinc plate is 60, and the copper plate is 95. When the plate is heated to 100 At ℃, 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) Stamping effect: After the magnesium alloy etching plate is made into a plate, the slope is suitable, The edge is sharp, the hardness is high, and the heating and cooling are fast in 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.
