aluminumAluminum belongs to one of nonferrous metals in metal category, because of the widely used alone is introduced as follows: the commonly used, which has two kinds of aluminum and die casting aluminum alloy.Mainly consists of more than 92% purity aluminum ingots as the main raw material, at the same time added to increase strength and hardness, abrasion resistance and other properties of metal elements, such as carbon, magnesium, silicon, sulfur, etc., composed of a variety of ingredients & other;Alloy & throughout;.
Aluminum, 1.1
Lu: xingcai common such as screen, aluminium windowAnd so on.It is to use an extrusion molding process, the raw material such as aluminum melt in the furnace, after extruding machine to mold flow extrusion molding, it can extrude different cross-section profiles.Main performance or strength, hardness, wear resistance GB6063 according to the national standards.Advantages are: light weight is only 2.8, does not rust, design change, low mold into, and the longitudinal elongation is as high as more than 10 meters.Aluminum has a shiny, matte appearance, its treatment process USES anodic oxidation treatment, surface treatment of thickness of oxide film is 0.12 m/m.Aluminum thickness choice, according to product design optimization is not as thick as possible on the market,Should see the cross section structure requirements for design, it can be 0.5 ~ 5 mm.Outsiders think more thick more strong, in fact is wrong.
Aluminium profile surface quality are difficult to overcome the defects: warping methods, deformation, black, and white line.The designer level and mold design and manufacturing process is reasonable, can avoid the defect is not obvious.Check the defect should be according to the provisions of the state inspection method, namely stadia 40 ~ 50 cm to identifying defects.
Aluminum in the furniture USES a very wide: screen frame, all kinds of hanging beam, countertops, feet, decoration, handle, go trough andTube cover, chair, etc., can be protean design and to use!
Lu: xingcai, though the advantages but there is also not ideal place:
Without oxidation treatment of aluminum easy & other;Rust & throughout;Which can lead to performance degradation, the longitudinal strength than iron products. Surface oxidation layer of abrasion resistance than plating easily scratched. The high cost, relatively iron products about 3 ~ 4 times higher than that of cost.
1.2 die casting aluminum alloy
Die-casting alloy compared with profile machining method, using equipment are different, its raw materials in aluminum ingots (Purity 92%) and alloy material, after melting furnace, into die casting machine mold molding.Die-casting aluminum products shape can design imaging toys, different shapes, convenient and various direction connection, in addition, its hardness, high strength, at the same time can be blended with zinc in zinc alloy.
Die-casting aluminum molding process points:
1, die-casting molding,
More than 2, coarse polishing to clamping material
3, fine polishing,
Die-casting aluminum production process, on the other hand, should have mold to manufacture, the mould cost is very expensive, than other mould, such as injection molding are high.At the same time, it is very difficult to mold repair, repair design error is difficult to reduce.
Die-casting aluminum faults:
Every time the production processing quantity should be more, the cost is low.Polishing the complex production cycle slow product cost is high injection molded parts about 3 ~ 4 times.Screw holes requirements have thrown a little (4.5 mm) in diameter that are stable even relay adaptation range: leg, classes Taiwan fittings, decorative head, aluminum sealing pieces, mesa and tea table, such as jacking very extensive.
