The production process of high-power waterproof aluminum alloy flashlight is very complex lock, the raw material is aluminum crack, after the mold stretch forming aluminum tube.Then each part is manufactured by CNC machine. In order to achieve better heat dissipation effect, refined processing is needed in the grain.Each part has been carefully designed to work when it is under 1 meter of water. In order to make the waterproof effect more outstanding, the charger with magnet contact is adopted.It has a lighting range of 500 meters and works continuously for four hours, using a magnet charger to make it more waterproof.
