Features Of Aluminum Die Casting

1. The design of aluminum die-casting parts is similar to that of plastic parts. Some design conventions of plastic parts are also applicable to die-casting parts.

2. For aluminum alloys, the temperature and pressure of the mold are much greater than those of plastics, which requires very strict design accuracy. Even with a good mold material, once there is welding, the mold has almost no life at all. Zinc alloy is similar to plastic, and the mold life is better.

3, there should be no concave sharp corners to avoid mold chipping.

4, although the accuracy of die-casting parts is relatively high, it is worse than plastic, and the draft force is larger than plastic. Usually the structure should not be too complicated. If necessary, the complicated parts should be broken down into two or more pieces.

5. Aluminum alloy screw holes usually only make taper pits and use post-processing. The post-processing amount of 0.3mm is usually reserved for the strict matching parts. 6. Aluminum alloy die-casting is prone to porosity, which needs to be considered in appearance. It is difficult to anodize the surface of aluminum alloy die-casting parts (containing silicon), and it usually takes a long time to appear black. Aluminum alloy die castings cannot be anodized and can be sprayed with oil or plastic. Commonly used alloy aluminum 6061, 7075, cast aluminum A356 coloring** are good.
