Now, in first- and second-tier cities, wall-mounted network advertising players have replaced manual shopping guides and have become popular products in major commercial areas, supermarkets, and office buildings. The components of the wall-mounted network advertising player include LCD screens, housings and other accessories. As the main accessories, what kind of housing should be used for the wall-mounted network advertising player? For the widely used wall-mounted network advertising machines nowadays, they are basically made of hardware shell materials. So, what are the special features of the wall-mounted network advertising machine shell materials? What is the difference between a metal shell and general plastic?
Wall-mounted network advertising machine shell material: stylish and exquisite tempered glass protection panel; 90mm thick aluminum alloy profile frame, baking paint process; high-quality cold-rolled steel back cover; inner frame and installation board use anti-corrosion, rust-proof galvanized sheet; wall-mounted network The surface of the advertising machine shell is treated with anti-rust phosphate, electrostatic spray and oil spray paint. If it is used in an outdoor advertising machine, surface reinforcement will also be used.
There are also wall-mounted network advertising machines on the market that have used plastic casings, but the plastic casings need to be moulded, and the characteristics of general plastic materials: plastic materials expand when heated, and the coefficient of linear expansion is much larger than that of metals; general plastic materials have an order of magnitude lower stiffness than metal ; The mechanical properties of plastic raw materials will be significantly reduced under long-term heating; plastic raw materials are very sensitive to notch damage; the mechanical properties of plastic raw materials are usually much lower than that of metal, and some online advertising machines use plastic shells and composite materials. The sum specific modulus is higher than that of metal. If the product design is reasonable, it will be more advantageous; generally, the mechanical properties of plastic raw materials are anisotropic.
For the wall-mounted network advertising machine shell produced by Maijun Technology on the market, it is generally a sheet metal shell with strong plasticity. Compared with the high cost of mold opening of the plastic shell, the cost is low, and the price is high. It is not special. Requirement, no plastic casing will be used. If the wall-mounted network advertising machine produced by the wall-mounted network advertising machine manufacturer is made of plastic casing, it is best to do a professional inspection test to prevent problems, resulting in excessive after-sales costs, which will damage the reputation and have a larger direct economic loss.
