Aluminum is widely used in the outdoor furniture

     The application of aluminum furniture industry is still very widespread, whether it is indoor furniture, outdoor furniture or office furniture. In icon outdoor furniture, there are many products are produced by means of aluminum as the material, such as rattan furniture, rattan sofa, aluminum wooden chair, umbrellas, wood lounge chairs, swings, etc., aluminum In our outdoor furniture industries widely used. For aluminum we have in the course of the following categories:
Aluminum type
Aluminum is one of the non-ferrous metal category, since a wider application, separate presentation is as follows: There are aluminum and die-cast aluminum alloy commonly used two kinds. Mainly by a purity of more than 92% of aluminum as the main raw material, while adding to increase strength, hardness, wear resistance and other properties of metal elements, such as carbon, magnesium, silicon, sulfur, etc., composed of various ingredients "alloys."

First, Aluminum

Common, such as aluminum screens, windows and so on. It is manufactured using extrusion process, the raw materials such as aluminum ingots melted in a furnace, after the mold out of the extruder extrusion molding, it can be a variety of different sections of extruded profiles. The main performance that strength, hardness, wear resistance according to national standard GB6063. Advantages are: light weight, only 2.8, no rust, design changes quickly, mold into low, longitudinal elongation of up to 10 meters or more. Shiny aluminum exterior, matte of the points, the treatment process using anodized oxide surface treatment reaches 0.12m / m thickness. Aluminum wall thickness according to product design

Taking into account the optimization options, not the thicker the better on the market, should look sectional structure requirements for the design, it can be 0.5 ~ 5mm uneven. Layman that the thicker the more hard-line, in fact, is the wrong way. Aluminum surface quality also difficult to overcome shortcomings: warping, distortion, black line, punch and white lines. Those with high levels of designers and mold design and production process is reasonable, less obvious defects can be avoided. Check the defect inspection method shall be prescribed by the State, namely sight 40 ~ 50CM to determine defects. Aluminum furniture in use is widespread in: Screen skeleton, various suspension beam, table legs, trim, handles, go trough and covers, chair tube, etc., can be ever-changing design and use!

Although the advantages of aluminum and more, but there are not ideal places:

Unoxidized aluminum handle is easy to "rust" which leads to performance degradation, longitudinal strength is not better than iron products. Wear inferior surface oxide layer plating easily scratched, high cost, relatively high cost of iron products out 3 to 4 times.

Second, die casting aluminum alloy

Casting alloys and profile processing methods, use of equipment are different, it's raw materials ingots (purity about 92%) and alloy materials, the furnace to melt into the casting machine molding. Aluminum imaging product shape can be designed as toys, shapes, convenient connections in all directions, in addition, it is a high hardness, strength, and zinc can be mixed with zinc alloy. Die-cast aluminum molding process points: 1, die casting 2, rough polishing material to the mold I 3, the fine polishing

On the other hand, the production of aluminum die-casting process, should die in order to manufacture, and its cost is very expensive mold, injection mold and other molds than are high. Meanwhile, mold maintenance is very difficult to design a feed reduction is difficult to fix an error. Aluminum Disadvantages:

Each number should be more production and processing cost was low. Polishing more complex production cycle slower than the injection molding of high product cost three to four times. Requirements should be bigger screw holes (diameter 4.5mm) connecting force becomes stable Adaptation: table legs, Pantai fittings, decorative head, aluminum sealing parts, countertops and coffee table backwater, etc., very wide scope. Aluminum materials in the furniture industry is an excellent choice, and its performance is stable, lightweight and soft texture. Very suitable for the outdoor furniture industry has been promoted.
