Characteristics of magnesium alloy die-casting box: 1. The weight of the ultra-light box is 40% lighter than that of the die-cast aluminum box, greatly saving costs 2. Ultrathinness-due to the high strength of magnesium alloy, it can be thinner than aluminum in design, about 30% thinner 3, fast heat dissipation - good heat dissipation performance, effectively protect the module circuit 4. Anti-interference a special anti-electromagnetic interference function 5. The tensile test of the box with higher strength reaches 300kg, which is stronger than aluminum 6, fast installation of a special fast lock, installation only takes 20 seconds 7. The box with higher precision is machined by CNC, with higher precision and seamless splicing 8, a strong versatility can be installed any kit hole processing, indoor and outdoor general 9. Easy maintenance: the entire die-casting box can be removed and maintained before implementation 10. High cost performance and complete production supply chain for large-scale production Die casting box of 500x500 magnesium alloy: Body parameters Gauge, H500 W500 * * the D60 (mm) Weight 2.8 kg Modules P3.91, P4.46, P4.81, P5.21, P6.25, P7.81, P8.91 Magnesium alloy of material Installation method hoisting, fixed installation Use environment indoor IP30/ outdoor IP65 Includes accessories for quick lock, handle, system/power mounting plate, connecting piece The box is black, gold and silver The doors are black, gold, silver, blue, orange Supporting products: 1.
