The surface quality of die-casting aluminum profiles also has defects that are difficult to overcome: up and down, deformation, black bars, bumps and white lines. Designers can avoid the above-mentioned defects with a variety of standards and reasonable mold design and production processes. Customized by aluminum die-casting manufacturersThe inspection of defects should be carried out in accordance with the inspection methods stipulated by the state. Generally speaking: the sight distance of aluminum die-casting castings is 40 ～50CM can identify defects. Aluminum profiles are widely used in furniture: screen frames, various hanging beams, table legs, decorative strips, handles, wire troughs and covers, chair tubes, etc. The design and use of aluminum die castings can be described as ever-changing! Although aluminum profiles have advantages, they also have disadvantages: aluminum is easy to "rust" without oxidation treatment, resulting in reduced characteristics, and the vertical strength level is not as good as iron products. The wear resistance of the surface oxide layer is not as good as that of the electroplated layer, and it is easy to be scratched. The cost is high, and the cost of aluminum die-casting is about 3 to 4 times higher than that of iron products.

Compared with the profile processing method, the die-casting alloy of aluminum die-casting products uses different equipment for processing aluminum die-casting parts. The raw material of aluminum die-casting products is aluminum ingots (purity around 92%) And alloy products, after melting in the melting furnace, enter the mold in the die-casting machine to be formed. The shape of aluminum die-casting products can be designed to be like a toy, which is diverse and convenient for connection in various directions. In addition, aluminum die-casting products have relatively high strength and can be mixed with zinc to form zinc-aluminum alloys.
