Aluminum type
Aluminum belong to non-ferrous metal category, one due to a wider application, individually described below: commonly there are two kinds of aluminum profile and die-casting aluminum alloy. Which up to 92% purity aluminum ingot as the main raw material, while adding increased strength, hardness, wear resistance and other properties of metal elements, such as carbon, magnesium, silicon, sulfur, composed of multi-component "alloy".
1.1 aluminum
Aluminum is common, such as screens, aluminum chair, showcase. It is the extrusion process, the melting of aluminum ingots and other raw materials in the furnace, after the extruder squeezed into the mold outflow forming a variety of different cross-section profiles, it can be extruded. The main performance, strength, hardness, wear resistance, according to national standard GB6063. The advantages are: light weight, only 2.8, does not rust, fast design changes, low mold into the longitudinal elongation of up to 10 meters or more. Aluminum appearance of a bright, matte points, the process, the anodized ...
... surface treatment of the oxide film reaches the thickness of 0.12m / m. The aluminum wall thickness according to the optimization of product design to choose, not on the market thicker, the better, you should see the cross-section structure requirements for the design, it can be uneven in the 0.5 ~ 5mm. The layman's view that the thicker the more tough, in fact, is wrong view.
Aluminum surface quality is more difficult to overcome the defects: warping, distortion, black line, punch and white lines. Designers with high levels and mold design and production process is reasonable, you can avoid these defects is not clear. Check the defects shall be prescribed by the State test methods, ie, line of sight 40 ~ 50CM to distinguish defects.
Aluminum use in the furniture is very broad: the wall skeleton, a variety of suspension beams, table legs of the table, trim, handles, wire tray and lid, seat tube, etc., can be ever-changing design and use!
Aluminum, more advantages, but there are also the ideal place:
Without the oxidation treatment of the aluminum is easy to "rust" resulting in performance degradation, the longitudinal strength is not better than iron products. The surface oxide layer abrasion resistance can not compare the plating layer easily scratched. High cost, high cost relative iron products 3 to 4 times.
1.2 cast aluminum alloy
Die-casting alloys and profile processing methods, use of equipment is different from its raw materials, aluminum ingots (about 92% purity) and alloys, melted by the furnace, into the molding die casting machine. The shape of die-cast aluminum products can be designed imaging toys of various shapes and convenience in all directions to connect, in addition, it is a higher hardness and strength, while a zinc-aluminum alloy and zinc mixed.
Die-casting aluminum molding process:
1, die-casting molding
2, coarse polishing to mold more than expected
3, fine polishing
On the other hand, die-cast aluminum production process, should be mold in order to create the mold cost is very expensive, than the injection mold and other mold. At the same time, mold maintenance is very difficult to design error is difficult to cut material to repair.
Die-cast aluminum shortcomings:
Each time the number of production and processing should be more high, the cost was low. Polished than the complex and slow production cycle cost compared to injection molded parts is about three to four times higher. Requirements should be large (diameter 4.5mm) to connect power to the screw hole was stable to adapt to the range: the legs of the table, Pantai connections, decorative head, aluminum sealing pieces, table and coffee table backwater, a very wide range.
Aluminum use of modern office aluminum furniture industry are usually selected 1.5mm thick aluminum-based, the rest of the production office wall aluminum are 1.2MM thick profiles, so need to pay attention to buy the office wall you select the screen thickness and so on.
