Aluminum die casting parts in the process of making is a pressure casting parts, in the development of the application of clothing good casting mold pressure casting machinery and equipment aluminum die casting machine, in the development of the use of aluminum or aluminum alloy profiles will be heated to liquid aluminum or aluminum alloy profiles are poured into the aluminum die casting machine inlet, aluminum die casting by aluminum die casting machine aluminum die casting, casting abrasive restriction of the shape of the specifications of the aluminum parts or aluminum alloy parts, the parts are generally referred to as aluminum die casting parts.

Aluminum die casting application advantages

1. Aluminum die casting parts to a certain extent can be produced to manufacture its complex appearance, clear contour and its thick-walled deep cavity metal parts. Since the molten metal maintains a strong flow under high pressure, it is possible to produce metal parts that cannot be produced by other processing methods.

2. The precision of aluminum die casting size is very high, in the development of use can reach IT11-13 grade, sometimes can reach IT9 grade, the roughness of the appearance of Ra0.8-3.2um, exchangeability is good.

3. Aluminum die casting parts material utilization rate is high. In view of the casting parts of the precision is relatively high, only through a little mechanical processing manufacturing can be installed application, some casting parts can be directly installed application. Its material utilization rate of about 60% - 80%, embryo utilization rate of 90%.

4. Manufacturing efficiency. Because of the fast filling, filling time is shorter, metal material industry condensation fast, aluminum die casting work cycle system speed faster. In all kinds of forging process, aluminum die casting way production efficiency is very high, suitable for mass production. Convenient and fast embedded parts. Convenient in the injection mold set up positioning organization, convenient embedded casting embedded parts, to casting parts part of the unique technical performance.

Aluminum and aluminum alloy surface treatment technology

Aluminum die casting parts because aluminum and aluminum alloy right crown surface coating adhesion is weak, and thus need to go through the surface cleaning, so that the surface layer to produce a layer of conversion film. This can not only enhance the combination of coating, and make the corrosion resistance performance is further improved. Aluminum and aluminum alloy surface treatment is generally: acid treatment → open water cleanup → cool water cleanup → oxidized film → cool water cleanup → cool water cleanup → organic chemical conversion → cool water cleanup → cool water cleanup → double-distilled water cleanup → control dry → dry and agitated
