Aluminum boxes have to first understand the following knowledge of aluminum and aluminum alloys I detail below: Aluminum is made of aluminum alloys are added elements such as aluminum - copper alloy, aluminum - zinc - magnesium - copper based hard aluminum alloy. There is an aluminum alloy is easy to process and have a high degree of heat dissipation. Particular part of the vehicle engine is particularly suitable for an aluminum alloy material. As with most of the computer chassis is made of aluminum - copper alloy. Mainly on account of the heat. Instrument box is mainly made of aluminum alloy skeleton, which is specially developed skeleton of aluminum, according to the need to be coated, such as oxidation process. Skeleton strong, wear-resistant, anti-oxidation, seems generous texture. Case fabric can choose different colors, so that the fabric has a varying diversity. ABS checkered panel uses the labor of its high density, wear Xinjiang aluminum props box, easy to penetrate sharp features, and a variety of materials can also be bonded aluminum props box, making the box more rigid, load-bearing other special instrument case stronger internal EVA sponge EVA ethylene - vinyl acetate ethylene copolymer ethylene - vinyl acetate copolymer called EVA, general vinyl acetate (VA) content of 5% to 40%. Compared with polyethylene, EVA due to the introduction in the molecular chain of the vinyl acetate monomer, thus reducing the high crystallinity, improved flexibility, impact resistance, heat-sealing filler compatibility and performance aluminum props box Inner Mongolia, is widely applied foam shoes materials, functional films, packaging films, adhesives, wire and cable and toys and other fields. In general, the performance depends primarily on the EVA resin content of vinyl acetate of molecular chains. 2001 China's EVA resin market consumption is about 290 kt. With the increased development and function of the amount of China's shoe industry films, China's demand for EVA resin will increase year by year. EVA resin in the ink, bags, bottles, gaskets and other fields have wider application. Air box Description: LED aviation box surface using PBS natural resistance materials, with fire, water, acid and alkali role Shanxi aluminum props box, PBS material for my company's patented products, this material crash, stretching and other characteristics. Box wall using (9MM) import joint board, box stickers (10-15MM) shock proof EVA cushioning materials, hardware accessories: butterfly lock, (straight) ball corners with brake caster and wheel sub vortex, handle.
