Qualified high-quality military equipment boxes, Aluminum, should meet the following quality criteria corners: corners and the box is not more than 0.4 mm slit, round aluminum angle aluminum and casing the gap is not greater than 0.3 mm, the diagonal dimension is not more than 1 mm, eye make up, align vertically spaced rivets, dislocation is not greater than 2 mm, Beijing instrument box factory, slit board (inside) is not greater than 1 mm. between the panel bracket, panel support and housing gap is not more than 0.3 mm, panel bracket height is not more than 0.3 mm on the top, bottom, left, right scale is not more than 1 mm, the parallel is not greater than 1 mm, custom fitted equipment box, the box should be fitted with iron plates fit, means strong. Close Page: hinge axis coincides with the top and the bottom seam strip, dislocation of not more than 0.3 mm, military equipment boxes, and the seam parallelism not more than 0.5 mm, and is highly adaptable open composed of aluminum, because aluminum has a low melting point. . This feature can be convenient and even more so industrial processes planning even more sensitive, thorough forging according to plan. Aluminum is made of aluminum to participate in some of the alloying elements, equipment boxes, such as aluminum - copper alloy, aluminum - zinc - magnesium - copper based hard alloys. Aluminum is light, low cost, mechanical properties (even by force) characteristics, there is the simple processing of aluminum and has a high degree of heat dissipation. Xiongxian plastic carrying case CATIC factory specializing in the production of military equipment boxes, aviation equipment boxes, medical equipment boxes, medical equipment boxes, aluminum instrument case, welcome to order.
