Many friends often have headaches when choosing metal engraving plates, because there are too many metal engraving plate manufacturers in the market, so it is especially important to learn how to choose high-quality and cheap metal engraving plates! To put it bluntly, it is enough to grasp the three most important points.
Look at the foam density: good quality metal engraving board and foam density is very high, its characteristics are very hard, gravity press, if the foam layer is not deformed, the quality of such metal engraving board foam is good! Second, look at its surface galvanized color steel plate: specially treated fluorocarbon paint galvanized color steel plate.
During the observation period, the surface color is bonded to the aluminum foil at the bottom of the board. Some manufacturers of metal engraving plates use ordinary galvanized color steel plates instead of fluorocarbon coatings, and the surface color will fade quickly.
Third, look at its price: as the saying goes, you get what you pay for. Coupled with various costs, it will definitely not be too cheap, at least at the local average market price, you have to be careful.
