identification note office furniture aluminum
office furniture often use aluminum, aluminum is very important for the quality office furniture. Aluminum belong to the category of non-ferrous metal, used widely due, separately described as follows: there is commonly aluminum and aluminum die-casting two kinds. Which is mainly composed of 92% high purity aluminum ingots as the main raw material, while adding increased strength, hardness, wear resistance and other properties of the metal elements, such as carbon, magnesium, silicon, sulfur, etc., consisting of a variety of ingredients & ldquo; alloy & rdquo ;. Aluminum common such as screens, aluminum windows and so on.
it is extrusion molding process, namely aluminum and other raw materials in a furnace after melting, extruding it through a die forming the outflow, it can be extruded various profiles of different sections. The main properties, namely the strength, hardness, wear resistance, according to national standard GB6063.
advantages are: light weight only 2.8 , no rust, design changes quickly, mold into a low longitudinal elongation of up to 10 meters. Aluminum appearance of bright, Matte points, its treatment process using anodized oxide film on the surface treatment to reach 0.12m / m thickness. Aluminum wall thickness by optimizing product design to choose, not the thicker the better on the market, should look sectional structure requirements for the design, it can be 0.5 ~ 5mm uneven. Layman believes thicker and tougher, in fact, is the wrong way.
aluminum surface defects: warping, distortion, black, white and punch lines. High level design designers were reasonable and die and production processes, to avoid the above drawbacks less noticeable. Check the defect inspection method shall be prescribed by the State, namely 40 ~ 50CM horizon discriminated defects.
aluminum furniture in the wide range of uses: screen skeleton, various suspension beams, tables, table legs, trim, handles, trunking and cover, chair control and so on, can be ever-changing design and use!
aluminum drawback:
no oxidation treatment of aluminum easily & ldquo; Rusty & rdquo; causing performance degradation, inferior longitudinal strength iron products surface oxide layer wear inferior plating. scratches easily. high cost, relatively iron products cost about 3-4 times higher.
die-casting alloys and profile processing method compared to using the device are different, with its raw aluminum ingot (purity about 92%) and alloys, the melting furnace into the die casting machine molding. Die-cast aluminum imaging product shape can be designed as toys, shapes, easy connection in various directions, in addition, the strength of its high hardness, and can be mixed with zinc to zinc aluminum alloy.
die casting aluminum craft points:
die casting, rough polishing to mold more than expected, fine polishing
On the other hand, the production of aluminum die-casting process, due to mold manufacturing, mold its cost is very expensive than injection other mold and so are high. At the same time, mold maintenance is very difficult to design a material error is difficult to reduce repair.
die-cast aluminum disadvantages:
each number should be more production and processing, low cost only. Polishing more complex production cycle is slower than the injection of high product costs about 3 to 4 times. Requirements should be larger screw holes (diameter 4.5mm) connection force becomes stable.
Adaptation: legs of the table, Pantai fittings, decorative head, aluminum seal member, table and coffee table backwater like, a very wide range.
